Hi Ive recently purchased an A4 TDI 140 S line Avant which was registered in may 2006 When giving the car a good clean Ive noticed spotting under the laqeur on the ally/silver window surrounds . Is this likely to be covered by the factory warranty ? I feel that it should as it should not be expected on a vehicle of this quality ? What do You people think ?? Anyone had a simmilar problem ??
