I loaned my 2004 Toureg to a friend and got it back with a busted light! I need to replace the front driver headlight assembly (7l6941015bq). I tried a knockoff part from parts.com that was supposedly compatible. It isn't. There are fewer pins on the new one. It fits just fine but no lights. Is there somewhere I can get a list of compatible part numbers that I can rely on? I am no expert but this seems like an easy fix if I can source the right part. Any help or advice will be greatly appreciated.
