I have just bought a 2004 Audi A3 TDI 3 door It is very tidy except for one in perfection which i want to rectify. The piece of metal that separates the front door to the rear quarter is dented almost like the seat belt has been slammed in it. I want to replace this but dont know what its called to search. Its just pop riveted into the body. I would post a pic but havent picked the car up yet. can anyone help?
