General Repair Information

CAUTION!
Before disconnecting the battery, determine the correct coding for the anti-theft radio.


NOTES:
- When addressing customer complaints it is absolutely necessary to know the functions and operation of the radio system
- For additional information: See Radio operating instructions.
- When retrofitting, repairing or troubleshooting: See Electrical Wiring Diagrams and Radio installation instructions.
- For detailed instructions (e.g. removing and installing trim panels): Interior Moulding / Trim
- Wherever possible, only genuine Audi parts should be used. Only then can trouble-free installation and optimal reception be guaranteed.
- All radio systems have anti-theft coding.

Retrofitting of radio Systems
- The connectors on the factory-installed radio wiring harness are designed for genuine Audi radios.
- Radios with different types of connectors must be installed using adapter wires.
- When connecting the vehicle speed sensor signal wire (on radios with the GALA function), take particular care to avoid short circuits, which could result in vehicle malfunctions (e.g. in the engine management system).
- Vehicle malfunctions may also occur if the vehicle speed sensor signal wire is connected to radios supplied by other manufacturers.
- When other radio units are installed it can have an effect on the antenna amplifier, since the original Audi radio units have a remotely driven antenna (the voltage supply of the antenna amplifier is driven via a center wire of the HF cable). Use a remotely driven adaptor. See your Audi Parts Department (vendor: Votex).
