Right. Over the last few days I've been commuting further in my 51-plate vRS 1.8T, five speed box, remapped but otherwise standard engine.

It started out as a small vibration sound, and has been getting ever-so-slightly worse every day. It increases with road speed, not engine revs - and dipping the clutch has no effect on it. My first stage is to be checking the gearbox oil level - the car's done a lot of miles and there's evidence of a small leak, but nothing major. How exactly do I check it?

If that isn't an issue, I'm going to get the wheel balancing checked, in case a weight has popped off recently. Is there anything else I should be looking at? I'm at work 8-5 most of the week, only tomorrow am I going to get chance to get it to a garage - and I desperately need it to be working for the morning. >crosses fingers< While I'm under it, I'll check daft things like the exhaust mounts etc- but it definitely seem drivetrain-related...

Does it change if you turn, e.g. going into a corner

Could be wheel bearings in that case. I just had both front ones replaced (£280... ouch)

It might be a wheel bearing as chicken_eyebrow said. I also changed mine. It's really simple to diagnose by a professional by only firmly moving the wheel; no need to take off the wheel.

Handily, my neighbour (of many years experience playing with cars) was about - he reckons also wheel bearing. Be getting it sorted tomorrow. Cheers chaps

£280!!......... ouch indeed.........when i replaced both my front wheel bearings on my mk1 octy vrs i only paid £50 for both bearings(i did fit them myself) even if you say £80 for both bearings(inc garage mark up) £100 a side to replace a front wheel bearing sounds a lot.
