Hi - I went to replace a light bulb on my a4 this weekend and came accross the strangest thing...
On the right side rear, the inner most light (narrow red), the harness can accept a bulb, but the plastic bulb shileds seem blocked for the bulb. Meaning if you pluged a bulb into the harness you would not be able to plug the harness into the shield.
Was looking on ebay and say someone selling a matching OEM set, and sure enough, theirs was the same way, the left side could accept the bulb, but it was blocked on the right.
Any ideas?
