I purchased a Volkswagen Golf GTI about two years and nine months ago. I've now noticed paint peeling off both rear wheel arches. Volkswagen's warranty team has declined my warranty claim on the basis that the problem was caused by "external influence". They suggest stone chips, which I find incredible bearing in mind the problem affects both arches and no other part of the car. The decision was apparently made on the basis of paint depth readings (which proved no previous damage) and photographs only. They will not produce any documents to show how they reached this decision or indeed to explain it. They will not alter their position and say if I wish to pursue the matter I will need to instruct a paint expert at my own cost. I think this is unfair as it attempts to shift the burden of proof on to me. I wonder if you might be able to offer any guidance in this matter please.
