Just bought 2011 model Polo GTi and it has a rattle in engine bay noticeable with windows open. Took it back to dealer who said it was normal and was something to do with 'forks' on the 'double clutch' mechanism of DGS gearbox rattling. Is this really 'normal'? Has anyone else got the same issue? I am a bit bemused why VW would sell the car with such a rattle!!
