Hmm, Honest Johns team replied to say they think it is the responsibility of the dealer now. Not what I wanted to hear!
Email sent to Chris, so I'll see what happens.
I agree with them. If the dealer carries out substandard work, it is theirs to rectify. VW may advise but I doubt they would pay to fix a dealer's work.
However Honest John advised me to forget it when I argued the dealers refusal to replace 2 of my 4 wheels with white worm, due to scuffs. He was wrong, cos I won
If you believe in your case, stick it out to the end. Have you considered getting the opinion & report of a second bodyshop? If that doesn't convince the dealer, I'd consider going to said second bodyshop, having all rectified, then taking the dealer to the small claims track of the county court to recover costs.
If the report favours your stance, take it to the dealer, tell them you'll get the work done & then will go to court. You'll probably get some joy that way.
