Hmeah,
I cannot respond to pm's on this site yet, not got enough posts.
I had my cambelt and tensioner replaced under the vw warranty. Not sure what engine code mine is, its an ed30 07 plate and had about 50k on the clock. I know some people have also had the water pump changed during this fix but mine was not. The car has been fantastic since having this work done and would strongly recommend getting it sorted if you have the same issue. Seems to be a common occurance.
Give me a shout if you need any further info.
James
