Right first post and not a good one!
I was changing my headlight bulbs earlier and when I fit them I turned the key in the ignition(not starting engine) to get my lights on and heard a funny buzzing electrical sounding noise coming from the engine? When removing the key from the ignition and turning the lights off the noise carried on for around a minute.
In a panic I put my old bulbs back in but the noise was still there!
Anybody able to put my mind at rest here? Or is something wrong?
My car is a 57 plate 2.0 TDI 170
