I have a 2004 2.0 TDCI Mondeo.
It was making a deepish raspy noise at about 1,700 revs, which I mentioned to the garage when it went in for a recent service. The noise seemed to be around for a few months and then would go for a while, before returning. Related or not, the garage said I needed a new timing belt and pulley. The noise was around for a few days after and then went, but is now back. When I accelerate, and the revs are at about 1,700 it gives this raspy noise until I increase or decrease the revs.
IS this just the noise of a diesel engine or should I be taking the car back to the garage?
