There is a definite case against VW with the way they are being.
Let me know if you decide to get your relative involved it would be good to know what they think of the warranty terms and conditions and what legal standing we have.
I am currently emailing the CEO of VW UK, my father is a professor at a well known business school and a lecture at University, he also works for the European commission as a consultant so i have brought him into it to see if he can help out. My car is over 12 years now but i took it in when it was 11 years and got fobbed of without any other questions.
Lets see if the CEO of VW UK replies to a .gov email address
