Hi everyone, My neighbour reversed into my rear bumper causing it to split, but it's also damaged the surround on the parking sensor. I have no idea if my sensors are factory fitted, so I don't know how easy it is to get a replacement part. Would anyone be able to shed some light on it please? Is the collar a standard size and available over the counter from motor factors? Or will I have to get in touch with Audi? Here's a pic of the part in question. Thanks, Callum.
