so had my 4th year service.
despite agreeing to replace spark plug and filters, they didnt.
guy from dealer phoned up today and said the tech wouldn't of put them in, as on the new system it doesnt tell them to, as VW changed their advice on when to renew them, its now 6 years!
I said thats a bit bad as it says it my service book 4 years and the car is now 4 years old and thats a long time not to change them!
also some flapy sensor (£123) has gone wrong, they put a request in, so waiting to find out if VW will do it on good will, as car only done 19k!
