Audi A1   Controls   Instruments and warning/indicator lamps  Warning and indicator lamps
If the indicator lamp flashes, the turn signals are on in towing mode. The trailer must be properly connected Link. If that is the case and the indicator lamp does not flash, there is a fault in the trailer system.
If a turn signal bulb on the trailer or vehicle fails in towing mode, the indicator lamp flashes twice as fast to indicate the bulb failure.
