Hi everyone,

I posted this a while ago but I've got more information now. Sometimes when driving my S2 with vigour I get a weird low frequency humming particularly in 3rd gear. I can often hear same said hum in 4th and 5th gear when driving at motorway speeds. When the noise occurs particularly in 5th gear, if I depress the clutch pedal fully and re-engage the clutch, the noise disappears. It can be intermittent at times and I first noticed in around May.

The gearbox feels slick enough and the car pulls away well on the clutch and is not slipping. The cars performance has remained unchanged i.e. still gives you a under acceleration. Any ideas from the wealth of knowledge out there?

I cannot say that I can be certain on this problem, but I would be looking at your release bearing.
