Hi everyone, I have 2004 conne cdti. I was doing some jobs on the car today and could hear a humming noise coming from somewhere. Ignition is off. FBH is ok, under bonnet pump is ok. I can't seem to trace where it's coming from. I thought at first it was coming from underneath the air filter housing, then closed the bonnet and listened through the grill still there. Thought it might be coming from the alternator, although the ignition is off. Has anyone come across this or any ideas, please.
