I purchased my RS4 aaprox 4 weeks ago from Aberdeen Audi - went up as hadnt seen the car in the flesh and noticed some tarnishing on the front grille
The chap at Audi offered to replce this for me as good will gesture - great.

It was peeing it down when got the car so didnt notice the same thing happening on all the aluminium around the doors and the boot sill when I got it home and polsihed car for the first time last week - its in on Friday at Teeside Audi to take photos etc and see if covered under warranty.
Has anyone experienced this - the marks wont polish put with metal polish/normal polish...
It surely must come under the 1yr warranty I got with the approved used audi (een under the manafacturers body corrosion warranty)
Help ...
