Squealing landie

On my 2.5tdi I am getting a squealing sound between 20 and 30 mph. It tends to go when I put my foot down. There is also a squeal at lower revs which goes when I put my foot on the clutch. All sounds go after 30 mph. Can anyone suggest what the problem might be ? It's not burning oil and other than that it pulls well. Ed

sounds like it might be your fan belt

I know what you mean, im getting a bit of squeeling at the mo, although at lower revs.

I just need to go outside and tighten the belt up, but its soo bloody cold i havent been bothered yet
