Hi all, I have an A6 C5 (97-), have taken advantage of the Halfrauds buy one - get one free. How ever one of my headlights is the original the other the previuos owner replaced - thus I have one weathered headlight and a 1 year old head light. Before I go looking at replacing the older one that stands out like a sore thumb, I was wondering if the later A6 headlights will fit mine? I have installed an aftermarket HID/Xenon system on another car in the past and it can be a bit of a mine field with getting the right parts and fitting etc etc. But not that technical. Anyway I am relativily new to A6 ownership so am not that familiar to what parts are interchangable. So do the later A6 headlights fit to the earlier A6's?
