its a funny tapping, not like a engine noise (although thats where it must be coming from i know) but it seems to be coming from behind the centre console to passenger side, hard to explain really

i found mine got quieter after a fresh oil change.

My cam belt tensioner from cold seems to be noisey making a rubbing sound, but once the engine starts to warm, the noise vanishes to leave a slight ticking noise below 1200prm then disapears which i class that as normal and not an issue to be concerned of.

i guess that might be it, it sounds like a very quiet indicator noise but i can only hear it when its stood ticking over

indeed, nothing to worry about. Tis the norm for TFSI.
Oil tends to loose it viscosity after a while and every time ive had oil changes, shes quiet as a kitten.

Does the Valve chain use hydraulic lifters which relys on oil feed to lift or is it valve and spring/rocker etc??. Anyone know????

My old CVH engine in an old ford i had used to have hydraulic lifters, and when the oil got old and thinner, it made the valves chatter causing a rattle or Knock. Perhaps the TFSI has the same "sort of" principle??

We all have a chain as well as the belt.  It is on the opposite end of the block and drives both cams.  I know a lot about this issue and it is not the normal sounds that our TFSI engines make.  IE.  Injectors,  carbon canister, purge valve or other stuff like that.  This noise that the OP is on about is the cam chain.  At the moment it only seems to affect early TFSI engines (AXX).  My engine sounds like a bag of nails when warm but nice and quiet when cold.  Have a read of this if you havn't already.

Its quiet long and now and again a few red herrings get thrown in,  but ultimatly the chain is at fault.
