This past winter was a bad one. I got a lot of rust spots that have flaked the paint right off in some areas. Looks awful and I'm embarrassed to drive my car now. So I'm going to be going in to Audi to try to get them to cover the repair under the 12-year rust warranty. I heard it's really hard for them to approve though so my question is, what can I do, or not do, to up my chances to get them to cover repairs? Anyone have any inside information?
I drive a 2011 A4 Avant. A white one so the rust really stands out.
This is the bottom corner of the driver's door, closest to the front wheels:

Just above the rear bumper:

And finally the infamous 3rd brake light:

What do you think my chances are?
