Each individual display variable of the onboard computer can be deactivated separately in the convenience 
menu under "SET". This applies to both onboard computer levels.

●

All display variables of the onboard computer can be reset in the convenience menu under "SET".

Note

The new features described in this 
section of control unit with display in 
dash panel insert J285 of the 
Audi TT Coupé ’07 will also be 
introduced in the current Audi A3 ‘04 
after the transition from model year 
2006 to 2007.

Immobiliser IV

The immobiliser is integrated in dash panel insert J285.
The immobiliser data is stored in the FAZIT database of AUDI AG.

The immobiliser IV can be adapted using the Audi diagnostic testers in the "Guided Fault Finding" and in the 
"Guided Functions" modes.
The diagnostic tester must be online in order to make a connection to the FAZIT database.

The dash panel insert is addressed via the address word 17 and the immobiliser via the address word 25. 
This means that data blocks, adaption channels and fault memories are handled separately.

Reference

For further information on 
immobiliser IV as well as the FAZIT 
database, refer to Self-Study 
Programme 294.

Display of cruise control system speed setting

When the cruise control system is active, the current speed setting is indicated on the centre display of the 
dash panel insert in the Audi TT Coupé ´07. If one of the two onboard computer levels is shown on the centre 
display, the set speed is indicated continuously. The speed is normally displayed in the position where the 
ambient temperature is indicated.

If the digital speedometer is shown on the centre display or if it is currently being used by the navigation 
system, the set speed is displayed after activating the cruise control system for 3 seconds, after which the 
display returns automatically to the original screen.

After "terminal 15 on", the function shown on the dash panel insert centre display before "terminal 15 off" is 
restored. In the example below, the digital speedometer is displayed.
