Infotainment
As in the 2016 Audi
TT, the second generation of the
Modular Infotainment Platform (MIB 2) is installed in the
Audi R8.
MMI Navigation plus (i8H)
with Audi connect (EL3)
Because the layout of the controls as well as all displays is
focused entirely on the driver, the Audi R8 does not have a
separate MMI display. All MMI displays are rendered in the
Audi virtual cockpit.

Sound systems
Audi sound system
The Audi sound system is standard equipment on the R8
V10 plus. It has five speakers and delivers a total of 140
watts power. The speakers are powered through Information Electronics Control Module 1 J794 and can be diagnosed individually.

Bang & Olufsen Sound System
The Bang & Olufsen sound system is standard equipment
for the R8 V10 and optional for the R8 V10 plus model. It
has 13 speakers with a total power output of 550 watts.
The speakers are amplified by Digital Sound System Control
Module J525 which is located behind the left seat. It is
connected to Information Electronics Control Module 1
J794 via the MOST bus.
To ensure there is enough bass volume, a subwoofer is
installed in the front passenger footwell in addition to the
two woofers in the front doors. The subwoofer membrane
is installed facing outwards towards the wheel arch. It can
be removed and installed via the footwell after taking out
the glove box.

Safety belt microphone
Safety belt microphones are integrated in both safety belts.
An additional conventional microphone is installed in the
overhead module. Seat Belt Microphone Control Module
J886 monitors and controls which microphone is used.
The safety belt microphones are only used if the driver’s
safety belt is fastened. Otherwise, the microphone in the
overhead module is used. The signals from the safety belt
microphones are sent first to Airbag Control Module J234
via the Infotainment CAN and then to J886. J886 also
receives information about the status of the front passenger - activated or not activated.
If the driver’s safety belt is not fastened, nor the passenger
side airbag activated, the passenger side microphone is not
used.
The safety belt microphone consists of three microphone
capsules. The wires for the individual capsules are woven
into the safety belt. When the safety belt microphone is
active, J886 continuously monitors which of the three
capsules is delivering the best signal and sends that signal
to Information Electronics Control Module 1 J794.
641_077
Seat Belt Microphone Control Module J886 is not active
until it receives a voltage signal from J794 indicating there
is a phantom feed the through “micro 1” wire. When activated, J886 has self-diagnostic capability and can be
accessed through Address Word A6.
Microphone capsules
If J886 loses voltage or is defective, an internal relay establishes a direct connection between the roof microphone and
Information Electronics Control Module 1 J794.

Climate control
Introduction
The 2017 Audi R8 is equipped with a single zone automatic
climate control system.
Six servomotors are used to control air flow and temperature. They are all identical in design and connected in series
to Front A/C Display Control Head E87. The servomotors
must be programmed via the Basic settings/auto-addressing procedure using the VAS Scan Tool if replaced.
E87 is connected to the display and operation CAN bus and
can be accessed using the VAS Scan Tool under Address
Word 08.
Climate control operation is supported by:
›› Sunlight Photo Sensor G107 (discrete wiring to E87).
›› Combined Air Quality Sensor G238 and Humidity
Sensor In Fresh Air Intake Duct G657.
›› High Pressure Sensor G65.
›› Humidity Sensor G355.
G238/G657, G65 and G355 are LIN bus participants connected to Vehicle Electrical System Control Module J519.
Their data is provided to A/C Display Control Head E87 via
Data Bus On Board Diagnostic Interface J533.

Front A/C Display Control Head E87
E87 has three turn-and-push knobs. The center turn-andpush knob has a display which can be used to set the cabin
temperature.
The seat heater buttons are located in a row of buttons
above the turn-and-push knob.
E87 has two cabin temperature sensors. Depending on
software version of control unit E87, either one of or both
of the sensors may be active. If both the temperature
sensors are active, the hardware computes a valid value
from the data provided.

Passenger compartment ventilation
As with all Audi models, the R8 has a forced air ventilation
system. This prevents the build-up of over-pressure when
closing a door.
Air flows from behind the parcel shelf towards the ‘B’
pillars and then through the speaker trims towards the
Audi Space Frame body.
The air flows through body intakes to both vent trims
located behind the doors on the exterior of the lower ‘B’
pillars.

Refrigerant circuit
The refrigerant circuit has two condensers. They are identical in design and like the two outer engine coolant radiators, are installed at a rotation angle of 180 degrees. The
refrigerant tube to and from the expansion valve is the
familiar internal heat exchanger design (coaxial refrigerant
line).
The A/C compressor has a direct clutch and is driven by the
engine through a drive shaft. An overload cut-out that can
interrupt power flow between the engine and compressor
in case of compressor failure is integrated in the A/C clutch.
R134 refrigerant is used in this vehicle.
Service operations
The high and low pressure service connections for refilling
refrigerant are located near the receiver/drier and can be
accessed through a flap in the luggage compartment.
After replacing the components of the refrigerant circuit,
care must be taken to ensure that the system is filled with
the correct level of refrigerant oil. The following quantities
of refrigerant oil must be added to the refrigerant circuit
after replacing the following components:
›› Replacing a single condenser: + 0.33 oz (10 ccm).
›› Replacing both condensers: + 0.66 oz (20 ccm).
›› Replacing the evaporator: + 0.66 oz (20 ccm).
