aligned vertically (z axis) in relation to the rear lid and side
panel. Elongated holes are used for alignment in the longitudinal and transverse directions (x and y axes).
Drain hoses on the right and left ensure that water can be
channeled out of the drive unit for the rear spoiler adjustment. Since molded hoses are used, the markings on both
sides must align with each other when the hoses are
installed on the mountings.

Panoramic glass sunroof
The Audi A7 can be equipped with a panoramic glass
sunroof which spans the entire width of the roof. A piece of
glass trim is permanently installed in front of the moving
sunroof panel.

The water drain hoses on the left and right are located at
the rear end of the roof insert. A new feature is that,
instead of being clipped into the sunroof frame, the water
drain hoses are attached directly to the roof reinforcement
at the top and the wheel housing at the bottom.

The glass panel can either be tilted at the rear or it can
slide open over the roof towards the rear. An electrically
operated blind provides protection against bright sunlight.

Fuel tank
The A7 has a 19.2 gal (73 l) fuel tank.
A tank cut-off valve is installed in the lower part of the
tank. The end of the pipe from this valve is located in the
upper part of the liquid trap. The TFSI tank requires several
roll-over valves for ventilation.

Filler neck (capless)

Breather line
(inserted through longitudinal
member)

How the tank is emptied
When driving, fuel is pumped into the side chamber by the suction-jet pump. The
vacuum produced in the pump causes fuel to be transferred from the side chamber
to the main chamber, so the side chamber is emptied first.

How the different tank capacities are achieved
Baffles are used to achieve the different tank capacities. The volume of the
fuel tank is changed by the baffles.

Capless filler neck
The capless filler neck technology used on the Audi TT is
used on the Audi A7. A dual flap system is used for dust
protection. The first flap provides a seal against dust, while
the second seals against fuel. Plastic seals are used to seal
the tank tightly against the outside.

Exhaust system
3.0 ltr. TFSI engine
The gas flow paths are very short because the turbocharger
module is located in the inner V. The catalytic converter is

bolted directly to the turbocharger outlet. This allows the
converter to achieve light-off very quickly after a cold start.

Catalytic converter module
The module is flanged-mounted directly to the turbocharger, which houses
the main and secondary catalytic converters. Both catalytic converters are
ceramic-type catalytic converters.

Engine mounts
The engine of the A7 has a three-mount system. There are
two switchable mounts on the engine and a hydraulic
mount on the transmission.

This system achieves an extremely comfortable ride by
switching the two engine mountings between soft (vehicle
idling, current supply to mounting on) and hard (vehicle in
motion, current supply to mounting off).

Power transmission
Overview
The power transmission system of the A7 has much in
common with the latest Audi A4, Q5, and Q7. Please refer
to the eSelf-Study Programs for those vehicles for further
information.

quattro with ultra technology

The 7-speed dual clutch transmission 0HL is new.

The quattro four-wheel drive system with ultra technology
is new to this class of vehicles (C8 series). To extend the
possible applications of this four-wheel drive system, it was
designed for engine torques up to 369 lb ft (500 Nm).

This is a new version of the DL382 transmission series for
four-wheel drive featuring quattro with ultra technology.
Specific measures have been implemented to raise the
torque capacity. Refer to page 26.
To transmit this amount of torque to the rear axle, the 0HL
transmission is used in combination with the four-wheel
drive coupling 0CX and rear final drive 09R. Refer to
page 26.

The following four-wheel drive concepts are available on
the Audi A7:
>> quattro with ultra technology.
>> quattro with self-locking center differential.
>> quattro with sport differential.

Front-wheel drive and hybrid drive versions are planned for
future model releases.

Drive versions
quattro with ultra technology/four-wheel drive coupling
Four-wheel drive coupling 0CJ or 0CX is installed in the
Audi A7 with quattro ultra, depending on the engine
version. The basic design and operating principle of the two
versions are identical. They differ exclusively in terms of the
coupling torque which can be transmitted.

Four-wheel drive coupling 0CJ is rated for torque levels up
to 590 lb ft (800 Nm).
Four-wheel drive coupling 0CX is rated for torque levels up
to 885 lb ft (1200).
Four-wheel drive coupling 0CX has two additional clutch
plate pairs to enable transfer of the higher torque level.
Four-wheel drive coupling 0CX is slightly longer than fourwheel drive coupling 0CJ due to these changes.

All Wheel Drive Control Module J492 can display two different
driver warning messages in the instrument cluster:
Four-wheel drive: fault. You can continue driving. Please contact dealership
Meaning: a malfunction has occurred. The customer can continue driving but
should drive to a dealership soon to have the fault corrected. The four-wheel
drive system may be unavailable.

669_064

Four-wheel drive: overheating. Please adapt driving style. See owner's manual
Meaning: the vehicle has been driven hard, causing the temperature of the fourwheel drive coupling to rise significantly. A more restrained driving style is
required so that the coupling can cool down. Until then, the four-wheel drive
system will be unavailable. When the temperature has dropped back down to
normal, the driver message will disappear and the four-wheel drive system will
be available again.
