Marriot motor group are shocking if you have an issue
When i had my mk5 Golf i took it to Barnards VW for servicing
Car broke down after cam belt change, told me to use my breakdown cover to get the car back to them. In the end they had to get a recovery truck as my breakdown would only take it within a 10 mile radius of my home.
When I got to the dealership a salesman I spoke to about a new car, joked saying I should've bought the mk6 Golf I was interested in. They fixed it but the mpg was bad so they had it back several times to sort it.
They offered me a free service, but because I bought the VRS they said they wouldn't honour that. Had several active complaints with VW customer services but to no avail.
In the end I had enough of them and bought the Octavia VRS. Which I bought from Simpsons Gt Yarmouth
