I have a squeak which I cant find, I can't hear it outside the car, its for sure not the engine, and its slightly worse when the car is cold. Only at tickover, take the car up to 1000 rpm and the squeak's gone. Sounds like its coming from behind the glove box, or passenger side front footwell. I guess its an engine mount or something, but all appear OK and I can find the squeak, even with the car up on ramps on tickover there is no squeak underneath, but get back in and you can hear it.
Any ideas ?
