Hi folks im in the same boat as a good few who has suffered with corrosion on the front drivers side wing
I noticed the problem in november the paint had started to bubble so i took it to volkswagen stockport for a inspection he got his paint digi tool out and measured the paint depth on both wings they were a tiny bit diffrent in depth he said my car has had a paint job on one of the arches not a chance i said.
Anyway cut the story short i got knocked back twice
the car is 54 plate gti with 32k on clock and has been well looked after im mythed with vw so im going to get the wing sorted myself
I just need to know what the job involves so it wont happen again and will it be costly its reflex silver
kind regards lee
