Thanks. I reckon the CRA 2015 will be my basis to argue on, if VW cut up rough. Not fit for purpose, and/or it's reasonable to expect the surround should last longer than 3 years.
I like a challenge. Off piste, but I used it against McLaren 5 years ago for my 570GT, when after a year of on/off problems, I wrote a letter and the dealer gave me all my money back, even though a year old and 5k miles.
