Hoping someone can help. I have fitted an S3 lower diffuser to my 2004 A3 3.2 s line bumper, now I need a tow eye cover. The diffuser I fitted is the one piece one that needs one part colour coded then masked to paint the diffuser. My local Audi parts section are useless, I went into there to order a diffuser only for them to get it wrong, so I'd like the part number in order to not waste anymore money. The part number I need is for a tow eye cover for a 3dr S3 with the one piece rear lower diffuser which has a part number of 8p3 807 521s. Thanks very much !
