Service Training

Self-Study Programme 382 describes the new
features of the convenience electronics in the
Audi TT Coupé ‘07. The proven electronic
technology of the Audi A3 ‘04 has been adopted for
the TT Coupé. The most striking new feature is the
automatic extending rear spoiler activated by the
convenience system central control unit.

In the TT Coupé, the driver information system (DIS)
in the centre display of the dash panel insert has an
extended settings and query menu.
The customer can use the settings menu to
configure functions and make adjustments. This
was previously possible only in vehicles with MMI.

The Audi TT Coupé ‘07 offers the customer
a multitude of functions and equipment options,
with the result that the number of control units has
increased considerably compared to the
predecessor model.
To ensure smooth interaction between control units,
the control units communicate with one another
across various bus systems.
The networking structure is largely identical to that
of the Audi A3 `04. In this self-study programme you
will be informed about the network topology of the
TT Coupé and about the installation locations of the
various control units as well as their functions.

The Audi TT Coupé ‘07 comes with new generation
2plus radios. The radios feature a new reception
concept as well as
MP3 compatible CD drives.
The TT Coupé, as do the Audi A3 and A4, comes with
a BNS 5.0 radio navigation system with MMI user
interface and CD navigation.
The BOSE Surround Sound system, which includes
12 loudspeakers driven by a 255 watt amplifier, sets
new standards in this vehicle class.
