156: odd sound on gentle decelaration
Hi all, I've started hearing a strange sound when I take my foot off the accelerator at certain times and speeds (but I only notice it when the windows are open). It's quite hard to pin down exactly when it happens but it seems to occur most when in 3rd gear and dropping slowly through about 58 km/h (no braking). It also happens if I rev in neutral when stationary, to about 3000 - just after the peak as the engine is slowing down again.
The sound is a kind of metalic grating, abrasive, perhaps rattling noise and I'm not sure exactly where it's coming from. Hard to describe really, sorry.
Can anyone suggest what it might be from my rather vague and dodgy description? Thanks.
