Vehicle Electrical System Control Module J519 supplies
voltage to Left and Right LED Headlamp Power Output
Modules 1, A31 and A27 as well as for Left and Right LED
Headlamp Power Output Modules 2, A28 and A32.
Headlight range adjustment is not implemented for the
headlights on the Audi R8. Cornering Lamp and Headlamp
Range Control Module J745 is only used to operate the
cornering lights. The LED headlight bulbs cannot be
replaced. Only the outer control units can be replaced
separately.
The power modules A31/A27 are responsible for the
daytime running light/side light and turn signal functions.
Optional equipment
Power modules 2 A32/A28 are responsible for activating the
LEDs for low beam, high beam, all-weather light, turning
light, static cornering light as well as the headlight fan.
29
The LED headlights are combined with High beam assist.
Tail lights
The tail lights of the Audi R8 are integrated in the rear body
side sections and border the bumper cover or the ventilation grilles at the bottom. Only LEDs are used for lighting.
Rear fog light
The sequential turn signal function has an additional electronic module in the tail light. The sidemarkers for the
North American Region are not integrated in the tail lights,
but rather have been transferred to the body side sections
of the vehicle as separate lights.

Back-up light
Activation
Service
The tail lights are activated by Comfort System Central
Control Module J393. J393 also determines whether
sequential or conventional turn signaling is required.
Neither individual LEDs nor the electronic components for
"dynamic turn signal operation" can be replaced on the tail
lights. In case of damage, the entire tail light must be
replaced.
The tail light LEDs are used for the Coming Home/Leaving
Home function.

Multifunction steering wheel
Two steering wheels are available for the Audi R8. A new
multifunction steering wheel, the R8 sport leather steering
wheel (PR 2ZC), is standard. The "drive select" and
"START ENGINE STOP" buttons are integrated. The individual drive select modes can be selected using the
"drive select" button. Because the Audi R8 has a keyless
start system, the "START ENGINE STOP" button is used to
switch the ignition on and off as well as to start and stop
the engine.

Multifunction Steering Wheel Control Module J453 records
all button movements and relays the signals to Steering
Column Electronics Control Module J527. J527 transfers
this information via CAN to the relevant control modules.
To ensure a rapid transfer of shift commands, all movements of the steering wheel shift paddles are transmitted
by discrete wires to Transmission Control Module 2 J1006.
The Start Engine Stop button is also connected directly to
Comfort System Central Control Module J393.
Multifunction Steering Wheel Control Module J453 is
diagnosed using Address Word 16.
