I notice some posts on rust. I have a 07 3.2l B6 4Motion estate, bought in Germany. I have had to weld in new steel at the top of both rear wheel arches. I notice that the front wheel arches are beginning to bubble at the top. I also have bubbles around the 3rd brake light on the rear spoiler. It seems to me like VW are having a problem with rust. on the B6. I have had older cars before (Peugeot, Merc, Renault, Fiat, Citroen and Morris Minor). I have never had this problem before. Something is amiss!!
