Whirring helicopter sound
« on: 18 May 2012, 10:39 »
Hi all,

It seems like there is always something in the way of getting my remap. Been put off for 4 months now!

So I am now getting a helicopter sound (I actually thought there was a helicopter above when it first started) which is getting worse and is now louder and turned into a sort of whirring.

It only happens when I am in gear doing 30mph-ish with foot off accelerator. It stops as soon as soon as I press accelerator or press the clutch in. It does sound like its coming from the front left but I'm not 100% certain (there is only so much moving around the cabin you can do while trying to drive!)

Any help would be appreciated.

Is it a grinding/rumbling sounding helicopter?

No, it doesn't sound like grinding and I can't feel any rumbling, I'd say its higher pitched than rumbling.

Yohan you are my hero! You helped me out with my blocked cat issues posted on mkivs!

Could it be a thrust bearing?

does it get louder when you go round a corner? is so itll be wheel bearing. if its louder on left hand bends itll be a right wheel, louder on right bends itll be a left wheel due to weight change etc. hope u get it sorted!

I've just fitted THS engine mounts with new bolts and the noise was there before fitting so I doubt it will be that. But will try and check.

I can also hear it very faintly when at standstill with the clutch up. When I press the clutch down the noise dies off after a second.

The car has a G60 flywheel and VR6 clutch with a new release bearing installed around 5k ago.

I will try and get a vid up but the cabin noise may drown out the sound with my phone mic.

Does this sound like a gearbox issue, I really dont want to have to buy and install a new one
