The saga continues!
Went to collect the car with the new rear bumper. Bumper is perfect, paint finish excellent but it needs to be blended-in as it is a couple of shades different from the quarter panels etc.
The bodyshop had advised VW that the blending-in process was essential (especially necessary with Red and Silver cars). But they are so penny-pinching that they would not sanction this.
I have therefore left the car at the bodyshop and instructed them to do my bidding. I will not collect the car until this has been acheived. The bodyshop will comply on Monday. I have also written to the Escalation Team at VW and have told them, in no uncertain terms, that this whole saga has been really extremely upsetting, time consuming and in the final analysis not commensurate with good customer care.
Nearly there!

And I don't think I will buy a VW again.
