Just had the car in at Vw skipton for a minor service, told Ben at servicing that I was concerned with the chain tensioner, he told me to bring the car in the night before so a couple of the technicians could listen to it on a cold start up, got a call this morning saying that there was a small chatter on start up and they are now liaising with the warranty company to have all the offending articles replaced, I would like to thank RocketRoss who recommended I go see Ben as at Vw skipton as they are understanding when comes to cars that a modified that other dealers would straight away say that certain things would invalidate your warranty, and the service was excellent, even got a brand new polo to shoot around for a couple of days in!
