Hi Matthew, Sandra mentioned you as someone who may be able to help me?-
I have a 2006 a6 saloon and have just facelifted the front and rear of the car.
My problem is that the new facelift leds needed re wiring and coding as an avant.
Someone did this for me but the led light sequence is incorrect, only one reverse light comes on, rear indicators and brake lights work but not as they should.
