Overview
This illustration shows the quattro drive of the Audi TT with
6-speed DSG transmission 0D9 and Haldex coupling 0CQ.
All model versions of the 2016 Audi TT will use the 09D
6-speed DSG transmission and 0CQ Haldex coupling.

The Haldex coupling software has been specially adapted
for the Audi TT. The new software provides both enhanced
driving dynamics and higher eciency.
The Haldex coupling software now makes more intensive
use of measured data relevant to driving dynamics and
continuously computes the exact driving status of the
vehicle, as well as assessing the driver's input and deter-
mining the road friction coecient. This allows torque
distribution to the rear axle to be perfectly adapted in any
driving situation. In addition, both the ESC control pro-
cesses and torque vectoring are incorporated into the
Haldex coupling control process. This enables the software
to anticipate the opening and closing of the Haldex cou-
pling, thereby reducing the reaction time signicantly.
To utilize the potential of this new technology, quattro
drive is coupled with Audidriveselect. Audidriveselect can
be used to select between dierent vehicle congurations.
A specic Haldex coupling setup is assigned to each con-
guration.

The Haldex coupling setup matches the known driving
behavior and the quattro-typical traction of the 2015 Audi A3.
dynamic
This setup provides more agile steering response. The
coupling is engaged as soon as the driver steers into the
corner, allowing it to react more quickly to the closing of
the coupling when accelerating out of the corner. The result
is a smaller decrease in torque in response to oversteer and
load changes.
In individual mode, the driver can choose a Haldex
coupling setup independent of other vehicle systems.
