Usually from cold. Just after I've turned the key and my car starts it makes a strange motor low pitch squealing noise that lasts about a second. It sounds like a the sort of noise you'd get on a couple of cogs skipping past each other. It doesn't usually happen when it's warm or the second time you start it. It starts up quite happily first time everytime- but just with this bizzare noise just after it fires up- almost sounds like the starter motor squeal noise you can get if you hold the key on to long when starting the engine? Any ideas?
