I have an 06 RS4 saloon that has just had it's 4 year service. When it went in I asked the Audi service guys to look at a warning light that blinks amber all the time. It is a symbol that does not feature in the owner's manual. Response was that it was something to do with the automatic headlamp range adjustment. But having referred the problem back to Audi Germany the only advice they could give was to take the bumper off and start tracing the fault back through the wiring circuits. As it has no effect on the day to day use of the car and sounds like an open cheque book repair I am inclined to forget it and put up with the blinking light. Anyone else had a similar problem?
