Hi guys, Hoping someone can shed some light on this for me. I have a 2007 A4 Cabriolet 2.0 Petrol. Yesterday I changed the number plate bulbs for some LED ones which were supposed to be canbus friendly, alas not as the dash error came up. I took the bulbs out and replaced with the original 5 watt bulbs which worked fine, but the dash error is still showing ?? On top of this and I dont know whether it is coincidence or not, but the traction light has appeared on the dash now and will not go out ?? I am racking my brains trying to think of an answer, I did disconnect the battery terminal for 10 mins, this does a reset on my Insignia not sure if it works that way with the Audi. Any help guys will be gratefully received.......
