000 – Air Jack and Fire Extinguisher
000 - 1 Air Jack System
- When driving, the bleed valve must be open (pulled out) in order to
ensure the air jack piston is fully retracted.
- Working under the car supported only by the air jacks without the chocks
(safeties) is forbidden.
- To prevent damage to the end stops on the piston rods, the air jack should
never be pressurised without lifting the car or alternatively the pressure
must be increased very slowly and in a controlled manner.
- Recommended operating pressure: 40 bar
- Never use cleaning products containing mineral oil.
- Do not dismantle the air jack – the system is pressurised even when
retracted!
- The tightening torque for the grooved nut (to secure the air jack) must
always be checked during a normal car check (spanner check).
- Tightening procedure grooved nut: see PDM 4SA 011 001
- If a loose or incorrectly mounted air jack is identified it must be replaced
immediately.

100 – 1.2 Engine Lubrication
The R8 LMS engine is equipped with a dry sump lubrication system. The oil tank
is located in the engine bay.
Engine cooling is made via an oil-water heat exchanger and an additional oil
cooler mounted in the sill on the left hand side of the car.
a) Engine Oil
Castrol EDGE FORMULA RS 10W-60 or Castrol EDGE TITANIUM FST 10W-60
Part number V31 748 009 --> 5 litre bundle
b) Oil Level Measurement
1. Position the car on a level, flat surface
2. Run the engine until the engine oil temperature reaches 100 °C –
110 °C (see chapter 901- Engine Warm-Up Procedure / Engine Start
3. Run the engine at idle speed for approx. 2 minutes
4. Switch off the engine and after approx. 2 minutes check the oil level
5. Oil level in ‘Fill’ range: add 1 litre oil until oil level reaches ‘Do not
fill’ range
6. The oil level should be in the upper third of the ‘Do not fill’ range
100 – Engine Ancillaries, Oil Tank and Water Cooler
Version 1 2016-01-01 21 / 113
The difference between the minimum ‘Fill’ mark and maximum ‘Do not fill’ mark
is 2 litres.
If the level is too high, oil can enter the air intake system. Do not fill higher than
the maximum ‘Do not fill’ mark.
c) Filling from empty
- Add 7 litres of engine oil
- Run the engine at idle speed for approx. 30 seconds
- Add an extra 1.5 litres of engine oil
- Run the engine until the engine oil temperature reaches 100 °C – 110 °C
(see chapter 901- Engine Warm-Up Procedure / Engine Start)
- Check engine oil level (see 901 - 1.2 Checking Engine Oil Level) and add oil
if necessary
d) Adding Oil during an Endurance Race
1 litre of engine oil should be added after every 8 hours of running in the race.
The engine consumes approx. 1 litre of engine oil per 1,000 km.
Oil pressure dropouts in the WinDarab data acquisition are a clear indication for
the engine oil level being too low.
For this reason, the oil pressure must be carefully checked and monitored in the
data. The oil pressure should not drop below 5 bar when the butterflies are fully
open.
e) Adding Oil during the Race (Accessory)
To add engine oil during the race is recommended to equip the oil tank with a
quick release coupling. Adding oil is made using a pressurised oil bottle. Refer to
the PDM (4SA 115 001) for the individual part numbers.
100 – Engine Ancillaries, Oil Tank and Water Cooler
Version 1 2016-01-01 22 / 113
Image 1: Adding Engine Oil during Endurance Races
After filling the oil fill bottle with engine oil (maximum 1.8 litres), pressurise
the bottle to 6 bar. This is made using a standard tyre valve on the bottom of
the oil fill bottle.
The bottle is fitted with a manometer to check the pressure.

Attention
The oil filler cap with quick release coupling is part of the endurance
homologation VO (VO -Variant Option).
When using a system, which is homologated together with other systems in a
single VO, the full extent of the homologated components must be used.
Please check the relevant VO in the homologation to ensure the assembly
complies with the regulations.

100 – 1.3 Engine Cooling System
The R8 LMS GT3 cooling system is specially optimised for use in a racecar.
The maximum cooler performance is only achieved when the cooler is cleaned
and the cooling fins (lamella) are realigned.
Scheme Diagram
Image 2: Scheme of Cooling System
Thermostat
The R8 LMS engine is equipped with a thermostat. The thermostat starts to
open at 85 °C. The thermostat is fully open at 95 °C.
Coolant
The capacity of the cooling system is 13.5 litres.
It is recommended that the coolant additive G13 (part number G013A8JM1) is
used.
The coolant filled at the time of delivery is frost proof to – 20 °C.
100 – Engine Ancillaries, Oil Tank and Water Cooler
Version 1 2016-01-01 25 / 113
The mixture ratio is 35 % coolant additive to 65 % water.
For all events in hot countries, Audi Sport customer racing recommends that the
additive ratio is reduced from the ex-works value to the ratio of 10 % additive
and 90 % water. This mixture ratio provides no frost protection.
The cooling system must not be operated without coolant additive.
The additive protects all the components in contact with water from corrosion,
reduces cavitation, lubricates the water pump and increases the cooling fluid’s
boiling point.
After reaching operating temperature, the expansion reservoir cap must not be
opened. The system pressure to increase the coolant boiling point would reduce!
Coolant additive mixture ratio:
- 10 % additive / 90 % water --> no frost protection!
- 25 % additive / 75 % water --> frost protection to – 12 °C
- 40 % additive / 60 % water --> frost protection to – 25 °C
- 50 % additive / 50 % water --> frost protection to – 35 °C
Filling the Cooling System
It is recommended that only distilled water is used to mix with cooling
additives. Using distilled water optimises the corrosion protection.
Only fill the cooling system when the engine is cold.
To fill and bleed the cooling system optimally it is recommended that the filling
device VAS 6096 is used.
100 – Engine Ancillaries, Oil Tank and Water Cooler
Version 1 2016-01-01 26 / 113
Special Tools Required
Cooling system filling device - VAS 6096
Adapter for cooling system tester - V.A.G 1274/8
- Fill the VAS 6096 coolant reservoir with approx. 20 litres of premixed
coolant in the desired ratio.
- Screw the adapter for the V.A.G 1274/8 cooling system tester onto the
coolant reservoir.
- Fit the cooling system filling device VAS 6096 to the adapter V.A.G
1274/8.
- Place the bleed hose (1) into a small container (2).
- The air extracted contains a small amount of coolant, which should be
collected.
100 – Engine Ancillaries, Oil Tank and Water Cooler
Version 1 2016-01-01 27 / 113
- Close valves A and B by turning the levers perpendicular to the flow
direction.
- Connect hose (3) to the pressurised air.
Pressure: 6 – 10 bar
- Open valve B by turning the level in the flow direction.
The suction pump generates negative pressure in the cooling
system, the dial indicator needle must move into the green range.
- Open valve A briefly by turning the lever in the flow direction to that the
VAS 6096 coolant reservoir hose fills with coolant.
- Close valve A.
- Leave valve B open for another 2 minutes.
The suction pump continues to generate negative pressure in the
cooling system; the dial indicator needle must remain in the green
range.
- Close valve B.
The dial indicator needle must remain in the green range, if so, the
negative pressure in the system is sufficient for the subsequent
filling.
Repeat the procedure if the dial indicator needle is below the green
range. If the negative pressure falls, the cooling system must be
checked for leaks.
- Disconnect the pressure hose.
- Open valve A.
The negative pressure in the cooling system draws the coolant out
of the coolant reservoir VAS 6096 and the cooling system fills.
- Remove the VAS 6096 cooling system filling device from the V.A.G
1274/8 adapter on the expansion reservoir.
- Disconnect quick release fitting 1 and 3.
- Open the bleed nipple on the water cooler until coolant escapes.
- Close the bleed nipple.
- Replenish coolant.
100 – Engine Ancillaries, Oil Tank and Water Cooler
Version 1 2016-01-01 28 / 113
- Tighten the expansion reservoir cap
The cap must click audibly and noticeably into position when
closing.
- Only check the coolant level when the engine is cold.
When the engine is cold, the coolant must be level with the ‘MAX’
mark.
When the engine is at operating temperature, the coolant level can
be above the ‘MAX’ mark.
Image 3: Expansion Reservoir
If air is still in the system after bleeding, it is recommended that the bleed
nipple on the water cooler is opened with the engine at normal operating
temperature until coolant escapes from the bleed nipple. This procedure should
be repeated until only coolant escapes after the bleed nipple is opened.

We recommend that the coupling O-rings are coated with “Molykote 1292”
grease after every event. Use the RFC-88-TN service tool to depress the inner
piston down until the 2 O-rings in the housing are visible. Afterwards the O-rings
can be lubricated and / or changed as required. The seals and lubricant are
available as kit (part number RFC-88-TN service kit) from Krontec. In addition,
we recommend that the coupling should be completely rebuilt after a complete
season or 10,000 km by Krontec (replace all seals, etc.).

Castrol SAF XJ 75W-140 or Castrol Syntrax Longlife 75W-140 (previously known
as SAF XJ)
Part number V31 748 005 01L --> 1 litre bundle
It is recommended that only gearbox oil approved by Audi Sport customer racing
is used.
Differences in the quality of gearbox oil influence significantly the wear of the
idler and fixed gears as well as the crown wheel and pinion.
300 – Gearbox, Drive Shafts and Ancillary Components
Version 1 2016-01-01 37 / 113
c) Oil Quantities
3.2 litres when oil cooler and oil pipes empty (initial fill when new or after
rebuild).
2.9 litres when oil cooler and oil pipes full (service and maintenance work).
Changing the filter and oil is mandatory after 500 km with a new car and with a
new gearbox. Otherwise, oil and filter change during service or after a maximum
of 6,000 km.
d) Oil Level Measurement
1. Position the car on a level, flat surface
2. To measure the oil level, remove the oil dipstick, wipe dry with a
clean cloth. Afterwards, screw the oil dipstick by hand to the final
position, then remove and check the oil level.
3. After the warming up procedure (tgear – 60°C), the oil level should
be immediately below the ‘MAX’ mark on the oil dipstick.
Attention
If the oil level is too high and/or the car is driven when the gearbox oil
temperature is too low, it is possible that a significant amount of oil will be
discharged from the gearbox breather!
e) Inspection
There are four inspection openings available (A/B/C/D).
The condition and wear of the dogs on the gears and dog rings, and the teeth on
the fixed gears, idler gears, crown wheel and pinion can be checked visibly.
The wear of the above-mentioned components should be checked regularly.

f) Service and Maintenance
1. Please refer to PDM 4SA 300 001 for 902 – Service and
Maintenance Contacts
2. Gearboxes should be returned for a rebuild after 6,000 km
3. Alternatively, a training course at HÖR-Technologie can be
attended, which enables customers to carry out rebuilds and
maintenance work (special tools required)
4. Rebuilds and training courses are implemented and coordinated in
conjunction with Audi Sport customer racing. Please contact

g) Differential
1. Preload fully adjustable between 50 and 300 Nm (hot)
2. Adjustment is made via the bolt on the differential housing cover –
remove screw plug in casing – turn the output flange until the
adjustment bolt is visible. Depress preload bolt with special tool
(V03 862 291 AC) and increase preload in clockwise direction. 1 Nm
on the ratchet equals approx. 10 Nm differential preload.
3. Caution: depending on the oil level and position of car, oil can
escape when the screw plug is removed.

Image 12: Screw Plug, Adjustable Differential Preload
Image 13: Adjustable Preload
Attention
The preload is approx. 100 – 150 Nm at delivery and with new gearbox. It
should be noted that the preload changes significantly before a certain distance
is covered with new clutch discs. Preload must always be adjusted when the
gearbox is warm.

1. Steer from left to right without engine running.
2. Steer lock to lock 10 times while refilling oil level and until the oil
level remains constant.
3. Start engine (idle speed) and run until the oil level sinks in the
reservoir, afterwards switch off the engine.
4. Refill oil to 3 mm above MAX 20°
5. Repeat procedure points 3 and 4 until the oil level remains
constant.
6. Start engine (idle speed) and check the oil level.
7. When warming the engine, steer repeatedly from lock to lock while
checking the oil level at the same time. Add oil if required.
400 – Front Axle, Anti-Roll Bar, Dampers and Steering
Version 1 2016-01-01 41 / 113
Attention
To prevents pressure spikes in the system, do not steer hard against the steering
stops when the steering is at full lock!
Oil level at room temperature between ‘MAX 20° and MAX 20° -3 mm’. Oil level
immediately after turning off engine at operating temperature between ‘MAX
80° - 3 mm and MIN 80°’.

To install bump stops and packers, the push rod (part with external hex) must
be removed from the piston rod. Procedure as follows:
1. Clean the piston rod thoroughly with iso-propanol
2. Clamp the piston rod using aluminium clamp blocks V03 862 342
AB (Öhlins part number 00727-05, sold in pairs)
3. Before removing the push rod, heat it with a hot air gun.
First mount the bump stops (material: foam) on the side of the damper body. A
full packer should always be mounted between the bump stops and the slotted
packers (material: POM, polyoxymethylene).
To refit the push rod, the threads on the piston rod must be cleaned, apply
Loctite 270 and tighten the push rod to 60 Nm torque.

Damper Adjustment
The compression setting is adjusted on the gold wheel
marked with ‘COMP’. The rebound setting is adjusted on
the black wheel marked with ‘REB’. Rotate clockwise to
increase the damping forces.
Rotate anticlockwise to reduce the damping forces.
To reset the adjustment, the wheel must be rotated
clockwise to the mechanical stop (position 0). Afterwards,
rotate anticlockwise click by click to open the valve again.
Count the clicks until the desired value is achieved.
Attention
Do not use excessive force to rotate the adjuster wheels. Sensitive sealing
surfaces could be damaged!

400 – 2.5 Camber Adjustment
Front Axle
On the front axle, the static camber is adjusted by adding or removing camber
shims between the upper wishbone mounting and the upright. A change in
camber also influences the toe angle. For this reason, the toe angle must be
corrected by adjusting the toe rod length. See table below.

Rear Axle
On the rear axle, the static camber is adjusted by adding or removing camber
shims between the upper wishbone mounting and the upright, and between the
toe rod mounting and the upright.
The static camber can be adjusted without influencing the toe angle. To achieve
this a pair of camber shims must be changed – which means the same coloured
shim must be fitted to the toe rod and the upper wishbone.

400 – 2.7 Brake discs
It is highly recommended that the brake discs and pads are bedded according to
the instructions issued by Brembo (see below). Bedding should prevent the
creation of cracks in the discs and pads and increase the durability. It cannot be
guaranteed that shorter versions of the bedding procedure will produce the
same level of safety and service life of brake discs and pads.
Bedding (source: Brembo Bedding Procedure V1.6)
In contrast to normal organic materials RB330, 340 & 350 show a different
behaviour during the bedding procedure, characterised by very high initial mu
that decreases to a stable level (a bit lower than the first stops). No
modifications in bedding procedures are needed moving from standard organic
pads to these ones; the bedding is mainly useful for the preparation of the disc
rather than the pad material. For ideal bedding, we suggest a phase with a
progression of constant pressure stops (#35 - 40) at increasing speed avoiding,
as much as possible, rapid deceleration. This procedure helps to build a uniform
and stable transfer layer that will subsequently ensure the correct friction; in
this phase the pad material is not modified but works to create a deposit on the
disc surface. (This is the reason why pre-bedded pads are not as useful as pre-
bedded discs). Then, a few high energy stops (#4, 5), at higher deceleration, are
needed in order to stabilize the transfer layer and to promote a repeatable
friction profile during use.
Step 1
Check the disc before use, in particular, the surface conditions (roughness,
damages, geometry) and be sure that the fixing of the disc corresponds to the
manufacturer’s drawing (out of plane, float, etc.)
If the disc is used, it will probably be covered by a transfer layer from previous
usage, we suggest, if possible, to clean it (sandpaper above FEPA 600, brake
400 – Front Axle, Anti-Roll Bar, Dampers and Steering
Version 1 2016-01-01 58 / 113
cleaner or similar) in order to avoid contamination during bedding. Normally,
this operation can be avoided because the RB330, 340 & 350 friction material
are initially very abrasive and able to clean up the disc surface automatically,
though time-to-bed will likely increase.
Step 2
The bedding is a very critical determinant of the life of brake components. An
incorrect or hasty procedure could compromise not only the life but also the
performance of components, especially brake discs. The bedding procedure is
needed essentially to prepare the disc for the race, so the processes involved are
the same if it is made on the track (GT, formula, NASCAR, etc.) or on the road
(Rally, where we suggest to bed on tarmac), it changes just the time. In order to
prevent unpredictable heat transfer on disc surface (uneven disc overheating),
and subsequent thermal deformation (cracks, vibrations) the bedding should be
achieved by application of groups of constant pressure stops (for a total of #35-
40 stops or alternatively 35 - 40 km of mileage) with gradually increasing of the
initial speed (and total brake energy). These brakings must be made well below
the tyres’ adhesion limit (50 - 60 % of the max race pedal pressure) in order to
achieve a corresponding gradually increasing of torques and temperature to the
brake system and promote a regular third layer deposit, the brake cooling must
be such to avoid overheating of the system (air ducts can be closed a bit, max 20
%, if disc temperature is too low). The maximum speed should be defined by the
track/road conditions and car features. During this phase the mu starts high
(0,8 – 0,9) and then decreases till the stabilization level, initial discs
temperatures can reach value close to 500 - 550 °C (*) (a bit less for pads, see
graph). Only at the beginning brake dust could be visible as normal consequence
of the initial bedding process. At the first stops, when the mu is still very high
(typical for RB340-RB350) and the disc/pads matching not yet optimized, the
heat transfer on disc could be uneven with small disc areas at high temperature,
despite the low energetic level of the brakings. At the beginning of the bedding
too strong brakings (high deceleration) must then be avoided, that could create
400 – Front Axle, Anti-Roll Bar, Dampers and Steering
Version 1 2016-01-01 59 / 113
local overheating on the disc and subsequent distortion on it. The heat
transferred into the disc becomes however higher (high gradient of
temperature) toward the end of the bedding because the disc surface is now
completely and uniformly settled up and the friction efficiency optimized, at this
point no risk of uneven heat distribution and distortion should exist.
Step 3
After the constant pressure brakings and the subsequent layer formation (step
2) a series of #4 - 5 high deceleration stops are desirable in order to set up the
layer and guarantee a correct functioning. To ensure that the bedding has been
done properly a homogenous, dark and slightly shiny layer must cover the
rubbing surfaces of the discs (the observation of the external surface is enough).
Darker stains are allowed and close to the fixing of the disc there may be visible
purple colored areas (indicating spike temperatures above 550 °C, see picture).
Narrow grooves (imperceptible to touch) are admitted, they will not affect the
performance in use. If the disc is too bright the bedding is not completely
finished, and a second and shorter procedure must be done. Pad appearance
should not indicate any mutation except a higher polishing of rubbing surfaces,
too rough surfaces (cracks, crumbling, detachment) could be caused by an
erroneous bedding, with too high thermal gradients.
* A simple way to check the correct temperature after bedding is to use thermo-
paints that turn white when the temperature is reached. Brembo offers a kit
including 3 paints: red up to 630 °, orange 550 ° and green 430 °C (p.n.
02.5711.10).

Blanking
Attention
Due to thermally induced mechanical stresses, cracks can develop despite
perfectly bedded brake discs and pads. A critical value for the magnitude of
these stresses is the minimum temperature of the brake discs at the beginning
of braking – especially at the end of a very long straight. Subject to circuit
layout, it is therefore necessary to partially blank the brake cooling air ducts.

Attention
In the majority of racing series’, it is not permitted to use blanking on the
exterior of the bodywork (e.g. using tape on the cooler grille). The blanking
must be made on the inside of the car (see Image 19).

700 - 1 Pedals
The pedal box has a large adjustment range in order to achieve the best possible
ergonomics for drivers of different stature. The individual possibilities are
described below in details.
700 - 1.1 Longitudinal Adjustment Pedal Unit
The seat is bolted firmly to the chassis. The pedal unit is mounted to a sledge
adjustable longitudinally. The adjustment range is 60 mm in 20 mm steps.
Image 20: Rails with Ratchet and Detent Mechanism
To move the pedal unit it must be released. A pneumatic valve as button is
located in the centre console. It activates a small pneumatic cylinder that
disengages the pedal unit.
700- Pneumatic Gearshift and Pedals
Version 1 2016-01-01 66 / 113
Image 21: Centre Console with Button to Disengage Pedal Unit and Main Switch to Activate
Compressor
The compressed air is taken from the compressor for the gearshift. If the car is
not used for a long time, the compressed air reservoir will be empty. In this
case, the MAIN switch in the centre console must be switch on. The compressor
will start to run. As soon as it switches off automatically, there is sufficient
pressure stored in the reservoir to disengage the pedal unit.
The pneumatic valve takes the form of a button in the centre console. This
means that as long as the button is depressed the pedal unit disengages.
A gas pressure cylinder moves the sledge automatically to the rear towards the
driver, who can then move the sledge forwards by pushing the cover below the
throttle pedal plate with the heel of their right foot.
700- Pneumatic Gearshift and Pedals
Version 1 2016-01-01 67 / 113
Attention
Only push the pedal unit forward using the area marked in the image below.
Pushing in other positions (e.g. on the left footrest or the brake pedal) increase
the force required and can cause the unit to jam!
Image 22: Push Surface on the Pedal Unit Cover
When the button is released, two independent springs push the lock into the
detents. If the lock is between two detents, the next closest position can be
selected by releasing or pushing with the right heel. The lock then clicks audibly
into position and the pedal unit is locked in position. Pressing with heel again
checks whether the unit is locked safely and thus ready for use.
700- Pneumatic Gearshift and Pedals
Version 1 2016-01-01 68 / 113
Procedure to Adjust the Longitudinal Position of the Sledge
- Ensure that the pneumatic reservoir is charged with sufficient pressure, or
switch on the MAIN switch and wait until the compressor switches off
- Press the button valve in the centre console
- Move the sledge to the desired position by pushing below the throttle
pedal plate with the heel of the right foot
- Release the button valve in the centre console
- The next closest locking position is achieved by pushing the sledge with
the right heel or by releasing the sledge
- Check that the sledge is securely locked by pushing with the feet

700 - 1.2 Throttle Pedal
The following adjustments can be made to the throttle pedal:
- Lateral position of the pedal plate
- Spring preload
- Damping
a) Lateral Position of Pedal Plate
There are two positions. The pedal in the left hand image shows the standard
position. The plate can be moved 10 mm to the right to create more space
between the throttle and brake pedal.
Image 23: The Two Possible Throttle Pedal Plate Positions
b) Spring Preload
A long compression spring is installed in the throttle pedal. At one end, a
plunger pushes the pedal against the foot, at the other end there is a threaded
stud with a nut.

Version 1 2016-01-01 70 / 113
Image 24: Nut to Adjust Spring Preload on Throttle Pedal
By turning the nut (16 mm AF spanner), the threaded stud is moved and the
spring preload changed. The basic setting is shown in the following image. The
pin in the slot shows the actual setting. The pin at the top means the minimum
spring preload is set. The pin at the bottom means the maximum spring preload
is set.

c) Damping
The damper of the throttle pedal is located below the cover on the left of the
gas spring used for moving the sledge.
Image 26: Pedal Assembly – Throttle Pedal Damper
The damping is adjustable. The standard setting is completely soft. Changing
the damping is made by rotating the cylinder relative to the piston rod. When
fitted, the damping is adjusted as follows:
- Remove the pedal unit cover (4 bolts)
- Disconnect the spherical bearing of the gas spring used to adjust the
sledge
- Remove the rear mounting bolt of the damper
700- Pneumatic Gearshift and Pedals
Version 1 2016-01-01 72 / 113
- Swing the damper to the right (see Image 27)
- Rotate the damper clockwise --> stiffer damping
- Rotate the damper anticlockwise --> softer damping
While rotating pull lightly on the cylinder so that the adjustment gears engage
in the piston.
When the resistance increases noticeable while rotating stop the adjustment!
Attention
Do not use force to rotate otherwise the adjuster segment in the damper can be
damaged!
Attention
The driver’s foot can get tired if the damper is set too hard.
- Remount the damper using the bolt
- To check the pedal force required press the pedal at different speeds to
simulate throttle application
- Remount the gas spring used to adjust the sledge position
- Refit the pedal unit cover (4 bolts)
- Sit in the driver’s seat and check the force required to press the throttle
pedal. Do this at different speeds to simulate throttle application.

The following adjustments can be made to the brake pedal:
- X Position (longitudinal offset between brake and throttle pedals)
- Y Position (distance to throttle pedal and to left foot rest)
- Z Position and angle (height and angle of pedal plate)
a) X Position
In the standard position, the brake pedal plate is on the same plane as the left
footrest and compared to the throttle pedal plate 10 mm closer to the driver. If
required, the brake pedal can be moved another 10 mm closer to the driver. A
second row of holes is provided in the brake pedal plate for this purpose.

Attention
The distance between the pedal plate and the driver should not be adjusted on
the brake master cylinder, otherwise the bell crank geometry changes and the
system can stick in the depressed position!
b) Y Position
To increase the distance to the left footrest or the throttle pedal plate to the
right, the brake pedal plate can be turned through 180°.

900 - 1 Software
RaceCon
BOSCH Motorsport supplies the RaceCon software with which the majority of
functions of the R8 LMS can be parameterised. This includes common functions
such as:
- Creation of display pages
- Lap trigger configuration
- Outing and lap counter configuration
- Pit speed configuration
- Suspension travel calibration (optional)
- Steering angle calibration
- Calibration of engine functions (butterflies, throttle pedal, camshafts)
The R8 LMS is delivered with a ready-to-race RaceCon configuration. Adapting
the display pages and additional functions is not necessary. If changes are
desired and teams are still unfamiliar with RaceCon, please do not hesitate to
contact customer support at Audi Sport customer racing.
a) Going online with the system
To make changes in the RaceCon project a connection with the car must be
created. This is made via the diagnostic plug at the passenger door.
Some factors can be changed offline in the project and subsequently
downloaded to the car after connecting.
The following data can be changed offline:
- Views and configuration of the DDU
- Lap trigger values
- Changes in the logger
900- Electric and Data Acquisition
Version 1 2016-01-01 88 / 113
The following changes can only be made online:
- Every calibration or adjustment
- Adapting the pit speed (after changing the value always copy the WP,
work page, to the RP, reference page)
After connecting to the car, a status LED (green, yellow or red) is displayed for
every component listed in the system tree.
Three green status LEDs indicate that the computer configuration matches the
car.
Changes made offline, for example a modified display view, are highlighted with
the yellow status LED. A message window appears automatically and prompts
whether the values should be adjusted (DOWNLOAD) – DOWNLOAD means that
something is written from the computer to the car.
Example
- Offline display changed -> Status yellow

- Offline lap trigger changed -> Status yellow
DOWNLOAD CONFIGURATION
- Offline logger changed -> Status yellow
DOWNLOAD CONFIGURATION
900- Electric and Data Acquisition
Version 1 2016-01-01 89 / 113
After making changes to the project, which are made online, the configuration
must be downloaded to the car in order to ensure that the computer and car
configurations match.
If the MS6.4-ECU status message is yellow after connecting to the car, this
indicates that changes were made offline, whereby the parameters between
computer and ECU differ.
Afterwards a message asks whether an UPLOAD or DOWNLOAD is desired.
Attention
In this case, a DOWNLOAD should never be implemented, but first an UPLOAD
to load the ECU dataset to the PC. Now it is necessary to make the desired
changes and to copy the work page to the reference page.
The MS6.4-ECU status LED must always be green.

900 - 2 Diagnosis
The R8 LMS on-board system architecture provides complete diagnostic
capability of almost every actuator and sensor. As a result, there are several
options available to detect and diagnose errors.
One option is via the RaceCon interface when the ERROR page is selected. This
page displays every monitored variable, which is controlled or received by the
ECU. Ideally, every error entry displays FALSE, which means that there are no
errors.
Occasionally error entries can indicate TRUE, when for example the
corresponding sensor is disconnected (e.g. damper travel and exhaust
temperature).
Several errors can only be diagnosed when the engine is running.
To control single components the option exists to implement checks both before
and during the engine start. In this case, the components are organised
according to their type. In this way, all relevant signal values such as voltage,
opening angle or similar can be viewed at a glance.
900- Electric and Data Acquisition
Version 1 2016-01-01 96 / 113
The following page view includes every component that should be checked
before the engine start. For example, calibrations can be checked if they were
successful.
To check every component, the following page view also allows every component
to be checked that requires the engine to be running.
Another option that provides an excellent monitoring function during the engine
start procedure is the information page on the display, which is usually selected
when warming up the car.
Important: Not all errors are displayed on the error page in the dashboard, but
in fact only those required for ideal operation of the car.
900- Electric and Data Acquisition
Version 1 2016-01-01 97 / 113
Monitoring values via the display during the engine start procedure is
complemented by another page view in RaceCon. The engine’s actual status is
indicated in the left field of the page. In contrast to the previous page views, the
pressures and temperatures are listed separately, which provides improved
performance when monitoring the most important values.
In addition, the combustion process in the cylinders can be checked in the
lambda and camshaft sensor fields.
The possibility to monitor the car during the engine start procedure internally
via the display as well as externally via the page views significantly reduces the
possibility of overlooking deviating values.

checked before running the car on track or selecting gears with the engine
running. If necessary, the gearbox potentiometer can be adjusted as described
below.
Checking gearbox potentiometer voltage
1. Turn on the main and ignition switches
2. Select neutral (N) – ‘gear’ value in display must be ‘N’ (rear wheels
can be easily turned by hand)
3. Selected display page 5 (‘startup’ page) and check ‘gearpot’ value
4. The value displayed should be 1.2 V ± 0.03 V
If the ‘gearpot’ value is outside the permitted range, the gearbox potentiometer
must be adjusted.
To check that the gearbox is in neutral (N) and not between gears, the position
of the shift barrel can be checked. The gearbox potentiometer must be removed
to do this. The groove to align the potentiometer must be set at ‘2 o’clock’.

901 - 1.3 Checking Gearbox Oil Level
See chapter 300 – Gearbox, Drive Shafts and Ancillary Components for
information about gearbox oil quality and fill level.
Checking gearbox oil level
1. Position the car on a level, flat surface.
2. To measure the oil level, remove the oil dipstick, wipe dry with a
clean cloth. Afterwards, screw the oil dipstick by hand to the final
position, then remove and check the oil level.
3. After the warming up procedure (tgear – 60°C), the oil level should
be immediately below the ‘MAX’ mark on the oil dipstick.
Attention
If the oil level is too high and / or the car is driven when the gearbox oil
temperature is too low, it is possible that a significant amount of oil will be
discharged from the gearbox breather!

901 - 1.5 Preparation Warm Up Procedure / ‘Warm up’
The following preparation must be made before starting the engine for the
warm up procedure:
- Ensure that the complete car is in a drivable condition and the car is on a
level, flat surface
- Remove the engine cover
- Lift the car with the air jack system, fit the air jack chocks (safeties)
- Check all the fluid levels (see chapter 901 - 1 Preparation before Engine
Start)
- The battery must be charged – to check the function of the battery and
alternator the battery charger should be disconnected during the engine
warm up procedure
- Fit the engine start wheel hub adapters on the rear axle
- Check the gearbox-potentiometer voltage value in neutral (N), see chapter
901 - 1.1 Checking / Adjusting Gearbox Potentiometer
- Ensure there is adequate air circulation in the pits / garage
- Switch on main switch and then ignition
- Deactivate ABS and traction control (TC) --> rotary switch to Zero (end

3,000 rpm
7. Heat up the engine and gearbox oil in sixth gear at 3,000 rpm
8. Monitor the engine water temperature (tmot – ‘startup’ display
page), this must not exceed 110 °C (if necessary position a fan in
front of the car)
9. During the warm up procedure check the steering system oil level
while turning the steering from lock to lock, see chapter 400 – 1
Filling / Bleeding Steering System
10. Check if the fan in front of the water cooler switches on when the
engine water temperature reaches 100°C
11. Start the cooling down procedure when gearbox temperature
reaches ~ 60 °C
901- Engine Warm-Up Procedure / Engine Start
Version 1 2016-01-01 106 / 113
901 - 2.2 Cooling Down Procedure
1. Downshift from sixth to first gear, do not apply throttle during this
procedure, with the engine at idle speed (do not activate the clutch)
2. Select neutral using the clutch
3. Check reverse gear engages. To select reverse activate the clutch
and press the ‘REVERSE’ switch in the centre console
4. Select neutral
5. Allow engine to idle for 2 minutes
6. Calibrate camshafts if necessary -> see chapter 900 - 1 Software
7. Check error codes on the display or via RaceCon
8. Switch off ignition, engine stops
9. Wait approx. 2 minutes, after check engine oil level, see chapter
100 – 1.2 Engine Lubrication or chapter 901 - 1.2 Checking Engine
Oil Level
10. Check all fluid levels
11. Check the engine for leakage, damage, electrical errors and / or
wiring loom problems
12. Switch off main switch
13. Check the logged data after the warming up procedure, reset the
outing and lap counter if required, calibrate the damper
potentiometers and steering angle sensors, see chapter 900 - 1
Software
Attention
The electronic gearshift prevents shift errors. If a ‘dog to dog’ situation occurs
during the warming up procedure, the ECU initiates an automatic throttle blip.
This is perceived audibly as the engine revs increase shortly. When downshifting
only use the shift paddle without using the clutch or throttle --> the ECU
controls the clutch and throttle.
