Match the vehicle code in the following control units
via selected diagnostics by coding "towing hitch
installed" (see coding example on page 11):

Coding AUDI A6 / ALLROAD QUATTRO
Please note:
The procedure described below for encoding and enabling the
trailer mode only serves for a general orientation and can vary
greatly depending on the model (motorisation / equipment). If
necessary further control units will have to be adapted by means
of guided trouble-shooting (e.g. motor electronics, distance
control ACC).
Encoding the ESP control unit:
• Guided troubleshooting
• Skip
• Function / component selection
• Chassis
• Brake system
• Self-diagnosing systems
• 03 - ABS and ESP
• J104 control unit for ABS and ESP
• Encode control unit (encode trailer coupling as installed)
