Hi Joe,
Thought i'd register and let you know that it sounds as if your cam chain, tensioner and adjuster may need changing.
Some people only change the chain and tensioner as the adjuster is expensive and you wont get much change from 1K if you have it all done. Although it makes sense to change it because the big cost with this job is the labour.
Bear in mind these T FSI engines are very noisy, using high pressure injectors. i have a 56 reg Gti with 60K on the clock and i currently have the same problem. normally fine when cold but after a few miles when the engines hot it sounds like a diesil!!
Hope this helps
