Hi All, I am hoping that some of you Audi brains on here may be able to help a new Audi owner out? I have a 98 A4 2.4SE and have just purchased via ebay a set of blacked out rear lights for it (the car is black). I have fitted them today and size and fit wise they are perfect and IMO look pretty slick. The problem is there seems to be an issue with the wiring as I now have an error on the dashboard indicating a rear-light problem. I have narrowed it down to the side/main bulb as the brake, fog, indciator, and reverse lights all function properly. Looking more closely at the new light harness if differs from the original in terms of location of each bulb, but also crucially the original fitting for the dual filiment main/dip light has a 2 prong connector, whereas the new fitting only has a single prong (I hope that makes sense?) Does anyone know of any modification I can make to fool the car into thinking the dual filiment bulb is still fitted, or any suggestions as to how to rectify the problem? Many thanks in advance, Hods. PS The lights are obviously for a B5 chassis, but the seller did not specify which year - are there different wiring harnesses?
