Yeah I know. I argued with VW about "goods not of satisfactory quality" and that it should be fixed at their cost, since it is obvious (as it occurred separately on 2 doors) that there is an inherent fault that was present when the car was sold. i.e. Sale of Goods Act rules apply.
They wanted to scam me £100 to "have a look at it" before they would decide whether the fix should be paid for by VW!!?!? I wrote to VW and complained and they just backed up what the dealer said.
In the end I gave up and just drove it for a year with the back drivers door locked shut and unable to open, and then miraculously it started working again and then I traded the car in anyway.
With all the money they spend try to attract customers in the first place, this was an object lesson in how to make sure your customer never buys one of your products ever again. Fucking idiots.
