2005 330i

jester77 · 11-26-2010, 07:09 PM

I have a 55 plate 330i SE Touring, which has been making a short, metallic-sounding 'screech' on start up recently. Seems to be worse with the colder weather. Only last a fraction of a second and then disappears - anyone any idea if this is normal or if I should be worried? No other symptoms.

I used to have an Audi S4 with a chain-driven 4.2 V8 which made a similar noise for a second before the chain picked up lube - this was considered normal by the Audi community. Not sure if this is something similar...

Any thoughts much appreciated!

Fan belt?

might be the power steering pump. I think the water pump is electrically driven. Check your power steering fluid level.
