Bumping an old thread to share my experience with this. 05 plate GTi, 69,500 miles, spotted the corrosion this weekend and had it in the garage (Wolverhampton) this week, usual spiel about corrosion guarantee not applying, but then after a bit of pushing it was agreed that would be carried out 100% cost as a goodwill gesture.
However, I was then told that they didn't have the facility at the dealer to check the paint thickness and submit the claim, and I would have to go to another dealer with a VW approved bodyshop. Rang all my locals (Tamworth, Burton & Derby) and they either didn't have bodyshops or were no longer VW approved. I got as far as Shrewsbury and they said they can do the work but couldn't guarantee the goodwill. It's an hour drive and an afternoon off work for me to get there just to get the info together for the claim.
Feel like just dumping the car in Wolverhampton and telling them to sort it, couldn't believe it was me doing all the ringing round trying to find someone to honour the goodwill!
Will update...
