Hi guys, I have RS200 Beams Turbo and have got a really annoying humming noise and I'm not sure what is causing it. It is a low hum when doing around 20-30 mph, I think it seems more so when de-cellarating it also does it if in gear or rolling ie foot on clutch.
I've had the car up in the air and no calipers are sticking there is no play in any wheel bearings and no noise when spinning wheels by hand. Had back wheels of the ground and with traction control off and engine running, gone through all gears spinning back wheels and the noise is not present at all.
ANY HELP IS APPRECIATED. (y)
