Morning,

First post here but I'm hoping someone might be able to help me. I'll try to explain the best I can but if anyone wants any more info then please ask.

Basically...

I have a humming noise coming from the engine compartment, now it intermittent and is worse either when I haven't used the car for a while (i.e. a day or two) or when i'm just cruising along and just maintaining speed. When I accelerate the noise goes away but if I decelerate using engine braking it is still there.

I have seen a couple of post similar on here that suggest a wheel bearing but the thing is with my noise is that it also happens when the car is stationary. One time when i picked it up from the garage it did it there and then when the engine was just idling over and the mechanic thought it was maybe a drive belt but he didn't take a very good look.

How can you tell if its a drive belt? or does anyone think its something else?

Cheers
