Just in response to the most recent thread posts, there's not a cat in hells chance of getting a repaired car and money for the fact that it's noticeable that the car's been repaired.
The insurer's job is to pay for a satisfactory repair to the point where you'd be hard pressed to know it has been repaired, except under expert scrutiny.
If the repair has been done by a VW approved repairer, whether it's up to scratch or not, you'll get your GFV or you'll just hand it back at the end of your PCP term. If the repair is crap, but done by a VW approved repairer, that's for VWFS to sort out with the repairer when you hand it back if quality of repair.is brought up by the dealer/inspector upon its return.
Absolutely do not highlight to the dealer that its been in a significant crash and had an extensive repair unprompted. Most people have some "equity" in the car against their next VW. If you highlight issues it may prompt extreme scrutiny rather than a cursory look over...and no equity to use towards the next one.
Do chase the insurer to pursue repairs to a satisfactory quality before you sign off on the job as complete.
