cam chain and tensioner!!!

[ukdub]

why do make u out to be a twat? as if i would have a car and not know if it had belt or chain, gti's have both, and 260 with parts fitted, parts from tps

As far as I can remember the chain and tensioner should be less than £100.  The adjuster alone is around £300, but VW, so TPS as well do a repair kit which when my car was repaired was around £280.  This 'repair kit' consists of an adjuster, adjuster/chain housing, gaskets and bolts, so parts alone came to £380 - £400.
Please dont feel the guy was making you out to be a twat,  most people if they are new or not mechanically minded to the 2.0 TFSI engine will not realise there is a chain as well as a a belt  

I will put his for future people seaching this topic.
All TFSI engine cars have a cam belt which should be changed at 60k or 4 years.  Its an option to change the water pump (do it) they also have on the opposite end of the engine a cam chain (right hand side under a aluminium housing) an adjuster and a chain tensioner.

I should add that you should budget for an adjuster kit as well, as 9 time out of 10 this is the problem.  If you change the adjuster at the same time you will save on labour charges at a later date if it doesnt cure your problem.  By the way, mine was quiet went cold and noisy when warm (on idle).  Give Awesome a ring (0161 776 0777), they took pictures of my worn adjuster, they should still have them
