When my car has been stood over night or after work (6 hours) I get a funny type of screeching noise constantly in time to the engine, the noise disappears when the car has warmed up, Iíve only noticed this in the last few months, when the temp gauge gets to about 90c the noise isnít there. On extra cold starts itís a little louder. Only hear the noise for first 20 minutes of using the car, cant hear noise from inside the car, doesnít get louder with the revs. the noise is not loud when sttod out side the car, you can just notice it.
The Astraís had:
New timing belt, tensioner and rollers @ 28,000 miles - 2 years ago
New water pump and timing belt @ 30,000 miles as owner said pump got a little loud Ė 2 years ago
Work completed by dealer.
Car is now on 45,000 miles,
Any advice please?
