active.

Automatic resetting of the selector lever
If the selector lever is in the tiptronic gate when the ignition
is switched off, it is automatically moved back into the automatic gate.
J587 determines whether the selector lever is in the tiptronic
gate or the automatic gate with the aid of Selector Lever
Position Sensor G727.

Resetting function
Starting from the position "transverse lock inactive", motor
V577 rotates the roller roughly ¾ of a turn in the direction
indicated by the arrow until the position "transverse lock
active" is reached. During that rotational movement, the
swash plate induces an axial movement (yellow arrow) on the
part of the cross-piece, thereby returning the selector lever to
the automatic gate.

Reciprocating plate

Locking cam in position
›› "transverse lock inactive"

The cross-piece (and, therefore the selector
lever) is pushed in the direction of the
arrow by the rotation of the swash plate.
At the same time, the locking cam moves
into the locking groove and locks the crosspiece. Consequently, movement of the
selector lever into the tiptronic gate is
barred.

Resetting the selector lever in emergency mode
If the tiptronic function cannot be performed due to a fault,
the selector lever is automatically returned to the automatic
gate and locked.

Transmission functions
Auto-P function
The parking lock is operated electro-hydraulically. See page
38. This allows Gearbox Control Module 1 to automatically
operate the parking lock, thereby enhancing operating
comfort.
The Auto-P function engages the parking lock automatically
(P-ON position) if the following conditions are satisfied:
›› Vehicle is stationary – vehicle speed less than 0.6 mph
(1 km/h).
›› One of the transmission settings D, S, R or M is active.
›› The engine is switched off – Terminal 15 is off.
On the 2017 Audi R8, the parking lock can also be engaged by
the driver by pressing the P button, provided that the vehicle
speed is less than 0.6 mph (1 km/h).
The parking lock is disengaged automatically (P-OFF position)
if the engine is running and one of the transmission settings D, S, R, N or M is selected.

Tip-shifting in D/S
Manual gear shifts can be executed at any time using the shift
paddles on the steering wheel (steering wheel tiptronic
controls) in transmission setting D/S. Once the steering
wheel tiptronic controls have been used, the transmission
remains permanently in manual mode (tiptronic mode).
There are two possible ways of returning to automatic mode:
›› Pull the selector lever back one position (position B1).

Activating transmission setting N

(holding P-OFF setting)

To be able to move the vehicle without the parking lock for a
limited amount of time, for example, in a car wash, automatic engagement of the parking lock can be prevented.
A condition for this is that the selector mechanism, the P
button and the transmission are working properly.
To activate P-OFF, transmission setting N must be selected
while the engine is running and then the engine switched
off1). When the ignition is turned off, engagement of the
parking lock is suppressed for a period of 20 minutes. After
19 minutes the following message is displayed in the instrument cluster: “Start engine to remain in N.” along with a
warning tone. If this instruction is not followed, the parking
lock engages after 20 minutes and the system shuts down.
If a speed signal greater than 0.6 mph (1 km/h) is detected
during this time, the period is extended according to the
driving time of the vehicle until the system detects that the
vehicle has been stationary for at least five minutes.
While the vehicle is stationary with the transmission in P-OFF,
power is consumed by the activity of the control modules, bus
network operation and the holding solenoid. If the vehicle is
stationary for an extended period of time, the battery may
become discharged to the extent that the parking lock automatically engages. Therefore, if it is necessary to keep the
transmission in P-OFF for an extended period, the parking
lock emergency release should be actuated.
More information on "Holding transmission setting P-OFF"
can be found on page 37.
On the 2017 R8 (100% keyless) the vehicle cannot be locked
while P-OFF is active.

›› Move the selector lever into the tiptronic gate and back
into the automatic gate.

Launch control program
The Launch Control Program regulates the maximum acceleration of the vehicle from a standing start. Please refer to
the Owner's Manual for instructions on how to use it and
follow the guidance provided.
The Launch Control Program in the Audi R8 has a particularly
sporty setup. In addition, forced up-shifts are performed in
tiptronic mode. Refer to page 14.
Notes
When pulling away with Launch Control active, all vehicle
components are heavily stressed. As a result, greater wear
may occur.
The number of Launch Control starts performed can be read
in the Measuring values.

Special features of the 2017 R8
Steering wheel tiptronic
The following functions can be selected using the shift
paddles on the steering wheel of the 2017 R8.
›› If both shift paddles are operated simultaneously while
the engine is running, driving position N is selected (both
moving and when the vehicle is stationary).
›› When the vehicle is stationary, the driver can shift from
the transmission settings P, R and N to M1 by operating
the Tip+ shift paddle with the brake applied.

Tip -

Tip +

›› Press-and-hold function: if the driver presses and holds the
Tip+ shift paddle while the vehicle is moving, the transmission changes up to the highest possible gear, for example,
from 3rd to 5th gear. If the driver presses and holds the
Tip– shift paddle, the transmission changes down to the
lowest possible gear, for example, from 7th to 3rd gear.
›› If a system malfunction occurs in the selector mechanism,
the driver can select driving position D with the Tip+ shift
paddle when the vehicle is stationary and with the brake
pressed. N can be selected by actuating both shift paddles
simultaneously. R (reverse gear) is not available.

643_025

These additional functions of the tiptronic shift paddles are
made possible by the use of redundant backup systems for
communicating the shift commands from the shift paddles
The shift commands are sent via CAN data bus to Gearbox
Control Unit 1 J743 and also by two separate signal lines to
Automatic Transmission Control Module 2 J1006. See also
schematic diagram on page 72. The information is then, in
turn, sent on by CAN data bus to J743.

Audi drive select – transmission settings
The comfort, auto and dynamic modes

The 2017 Audi R8 is equipped with Audi drive select. That
means, depending on the vehicle equipment, the driver can
experience the performance capabilities and dynamic handling characteristics of different vehicle systems.

comfort and auto modes are identical regarding transmission
setup. The shift points and the gear shifts are comfort-orientated.

In addition to the familiar Audi drive select modes –
comfort, auto, dynamic and individual – the 2017 R8 has a
performance mode. Within performance mode itself there
are three sub-modes – snow, wet and dry. Those setups allow
the handling systems to be better adapted to the road
surface conditions. The Audi drive select handling system
utilizes the electronic stability control (ESC) system in performance mode.

In dynamic mode the sport program S is selected in the
gearbox. In the sport program the shift points are at higher
engine speeds and shift times are reduced. This makes for
better power delivery and more noticeable gear shifts.
The overview on page 15 shows the effects of the various
Audi drive select modes on the transmission setup.

Basic information about Audi drive select on the Audi R8 can
be found in eSelf-Study Program 990363, The 2017 Audi R8
Introduction. It explains how the transmission control system
reacts to the various Audi drive select modes.

Performance mode
Performance mode is standard on the V10 plus and optional
on the V10. In performance mode, the transmission setup is
very sporty. That means that the transmission works to maximize power delivery from the engine; comfort plays a secondary role. Gear shifts are performed at very high engine

speeds, gear changes are very fast and distinctly perceptible.
Performance mode can only be activated and operated using
the Performance button the steering wheel. The Performance
button allows the driver to activate or deactivate performance mode directly and in any Audi drive select mode.

Information
The following applies to vehicles for the North America region and all other countries from model year '17 on: If performance mode is
selected, Gearbox Control Unit 1 switches to tiptronic mode MS+ and automatic mode is not available.

Please note that the stabilization functions of the ESC and traction control systems are limited when performance mode is
activated. You should only activate performance mode if you have the necessary driving skills and the traffic conditions
permit. There is a danger of skidding and losing control!

Performance button
The Performance button is a touch switch
with an adjusting ring. The adjusting ring is
used to select the snow, wet and dry modes.
Those modes have no effect on the setup of
the transmission.

Installation space requirement from axis of transmission input
shaft (= crankshaft axis) to bottom of transmission

The 0BZ was developed specially for the new MSS platform1).
That platform requires a transmission with a short installed
length.

With an installed length shorter than 23.6 in (600 mm), the
OBZ transmission is more than 5.9 in (150 mm) shorter than
the R tronic.

Those requirements were essentially achieved by means of
the following design features:

Together with the engine's dry-sump lubrication system, it
achieves sufficient ground clearance at the same time as
providing a low center of gravity for the vehicle while keeping
within the baseline limit.

›› Compact dual clutch with directly adjacent clutches.
›› Positioning of the Mechatronic module on the side of the
transmission.
›› 3-shaft gear-set configuration.
›› Positioning of the rear final drive and the PTO shaft for the
front final drive.
