I thought that 2003 and up Audi had rust proof panels. I have 2 small rust spots starting on my door. Would Audi do anything for that?

 

Unless it's perforated from the inside right through to the outside, they are unlikely to warranty it. Depending on where it is, you might want to try scraping the rust off and sealing the spot with something like clear nail varnish

 

I had the driver's side doorblade start to rust after the car made it through the winter. Took it to the dealer and they wouldn't warranty it. They said there's only corrosion protection warranty on rusting from the inside out on major body panels (conveniently not doorblades). The dealer still painted it for free when I bought a new blade.
