When I start the car up be it in the morning or evening.....as long as the oil hasn't warmed up or anything I can hear like a continous sqeaking noise whilst ideling. This appears to be coming from the fan belt/cambelt that is on the left side of the engine bay which is visible..... As soon as the car is warmed up the noise disappears? Has had a service and what not they didn't mention anything about it being a problem? Maybe they missed it out? Does anyone else have this problem?
