Thanks mate - so whilst off/cold just have a wiggle of things to see if anything is loose?
Or get a ear round them whilst running?

Is there some kind of Screwdriver trick? As in prod parts and listen? This sounds nuts but sure ive seen Edd China do it on Wheeler Dealers?!?

Just been out on my lunch break - no room for me to get a hand down for a wiggle?
I guess I will need to get it on the ramp to get from underneath?

Im not an expert on the 2.5 tdi in trhe Audi but on the 2.5tdi T4 a similar sound would occur when the vibration damper pulley was disintegrating. ie rubber inner starts to break up and if it goes it takes the cambelt and everything with it. Which is my way of saying get it checked whilst its not costing you anything. As the pulley wears the alignment also shifts and the belts start to rub or catch. I could also be talking rubbish but that was common on 2.5 tdi after about 120k.
