52k on the clock now, been running fine.

Has started to make a humming noise both at idle, and at low speeds up to around 1500rpm.
Doesn't matter if the car is not moving, so it isn't from road noise or tyres. it is something to do with the engine. Does it in Park, or Drive.

I have had a browse, looking for similar, but most people are talking about road noise, or petrol engines. As it does it when stationary, it can't be the brakes etc.

thinking it could be a bearing on something, or some sort of induction/air harmonic??

Anyone else had this on the 3.0 CRD?
