At a guess, is the car automatic/DSG?

But I don't want to stop you having them replaced. Just keep us updated how the replacements perform.

Going back to my original point though - it is surface oxidation that looks most likely caused by running the brakes warm and having them sprayed with water. The patterning relates to the heat dissipation that a calliper might exhibit in such conditions. Looking more closely also, it seems that the oxidisation could be removed rather easily with a wire brush.

Top of the day to you Sir!
Thank You mikinoz,

Yes it is DSG,

According to dealer they can clean it but of corse rust will come back

VWA representative first assessment was that rust was caused buy acid rim cleaner.

When I asked them why it is only part of the brake calliper front rusted this is part of their e-mail: "...brake calipers were exposed to some sort of liquid or chemical which may corrode the callipers, further research is needed to determine what has caused the calipers to rust."

Dealership technician privately told me that callipers are teflon coated for rust protection and that they did not have such a case with relatively new car.

Anybody here with same problem.

Official VWA position (I am still waiting for written conformation) is that I have to prove that rust is caused buy callipers defect.

I was not asking VWA to replace callipers - just to fix them (paint or clean them and protect with something).

Can't void the warranty on them as they already won't warrant them, right?
If not fixed by VWA - of course I have to paint them.

Probably I will be looking for professional (my understanding is that callipers should be removed (or it is better) and than painted) but not sure which business (brake shop or...) is doing that and what I can expect to pay ... any recomendation for Perth.
