First thought I said Ming blue but might be a Merlin purple....nah it's a bit dark. I'm going for ming blue.
As for the door blade, you need to remove two rubber bungs from the inside bottom of the door. Then remove the two Phillips screw from the inside (being careful not to drop the screws inside the door). The door blade has a nylon runner that sits inside a recess inside the blade. I replaced a blade about 5 years ago with a new one from Audi and it just started doing the same as yours again this summer! (Wtf?!) So, a few months ago I removed the blade and cleaned it all up and used an epoxy resin to stick the white nylon runner back into the blade. 5 months on and it's still good. Try to repair it like me but if you don't succeed a new blade is around £160 inc vat from Audi and the colour won't match. I had to get it painted before I fitted it (along with my old rear door blade) to ensure a good match on one side. The screws and washers can be re-used but I had to drill my screws out as they were rusted to sh1t. Audi will sell you new screws for about 60p each.
