I have a 2.0 tdi bkd quattro

iv just got back off holiday after leaving the car with my local garage and having had the turbo rebuilt, cam belt oil and filters, and an MOT, I can hear what sounds like a grinding noise from around the engine gearbox area. it only happens above 10 MPH and only when im not accelerating. the clutch position does not change the noise at all.

it might of been there all along but i only notice it now the turbo has stopped making a rachet.

any ideas before i go back and ask the garage about it?

thanks in advance Jack
