It is a 1.6 tdci the coolent level is fine the controls are facing the windscreen and air con is off the humming is louder than the engine when idling

Hi there thanks

ok the noise most customers relate to is caused by the engine cooling fan

if the direction controls are to the window some gave a strategy that brings the air con on as cold air demists the windscreen quicker

This would be the first check ie move the air vents to face and put the temp mid way switch off and restart the car

If the noise is still there pop the bonnet and see if it is the actual cooling fan that is on constant

As we see the 1.6 tdci fan stay on even after keying off due to the dpf regeneration process

Kindest regards ***** *****

I have had the bonnet up and the fan is off but the humming is stil there

Hi thanks

Does the humming noise vary with engine revs

Does depressing the clutch make any difference

Does putting air con make any difference

Is the noise more from the drivers side /accessory drive belt area

Kindest regards

The noise is constant and does not vary even when you are clearing screens it does not make any difference when reving it seems to be more to the rear on the drivers side and its an automatic estate

Has any work been carried prior to this happening

If possible Can you post a video of noise

Customer: replied 7 months ago.
I have no work done

Is it more a buzzing noise

Customer: replied 7 months ago.
No its a constant droning

Hi thanks

Ok the first thing in this area that should be checked is the one way fuel return Vance thee were prone for failing and causing a noise similar to a droning noise

This is a small metal valve that is located on the fuel return lines to the fuel pump which is located at the drivers rear of the engine bay

Kindest regards ***** *****
