I was just going through the posts because I had (what was supposed to be an excellent "guy" repair my 2006 A3 after a "T" Bone) and the rustiest have appeared on the rear passenger door. How far did you manage with your repair or parts? Did you DIY it r have it professionally fixed? I'm in TO too and have used Downtown, Midtown, and a great VW/Audi specialist in the west end.
