I had the same problem. It was the EGR cooler pipe from the turbo to the pre-cooler before the exhaust inters the EGR valve. I replaced it myself. the pipe cost $103.00 from TDI parts online. There is a kit to block it off but it was more than the pipe. Blocking it off turns on check engine light. The EGR heat exchanger also preheats the coolant that goes directly to the heater core for quick warmups in the winter. Good Luck!

this sounds like an adjustment issue. you did not mention the mileage...The clutch is released by a bearing, this release bearing needs to come back off of the fingers of the clutch pressure place, early wear and noise happens.

Near the end of the clutch life, you may find that you cannot release any more, if your model is adjustable.

Start with proper clutch release adjustment.
