Dual Mass

sassy_one

Hi,

Does anyone know if a dual mass noise can be caused by a car sat for a period unused and then go after it's been used for a while?

The reason I ask is I never had any noise prior to lockdown where it's been sat for weeks without use.
However, I seem to have a very very faint noise which I suspect to be the dual mass flywheel.
When you press the clutch pedal in and disengage the clutch the noise goes.
Its very very faint but the change of note you can hear it while outside the car.

I'm wondering if this will go once it's used again?

Once they go they go, they don't magically fix themselves.

Are you driving it or just running it to keep the battery charged? Reason I'm asking is because the clutch friction plate has metallic particles in it and when a car has been stood for a while it's like the brakes, it "rusts" to the flywheel so the noise could be the clutch plate just scrubbing a bit of rust off the surface.

Also if there's a fair few miles on the clock you can get a bit of play in the gearbox and when putting the clutch in and out that can change the noise.

The noise DMFs make when they're going is a rattling.

I've not done any distance in it, it was stood for weeks and today I moved it less than half a mile and it sounded like a rubbing noise lightly, like when you apply the brakes and the car has been stood for a while, with the disc getting smoothed off again.

Theres no rattling, it seems just to be there very faintly, it's so faint I'm not bothered I am just concerned incase it's a early warning the DMF might be on it's way.
Until I can take it any distance I obviously can't check but I'm just worried now incase 😬

Try a 'racing start'
Honestly, go out, raise the revs high and slip the clutch like hell - like you're Lewis Capaldi-Hamilton
You'd be amazed how many clutch issues are sorted out by that, it removes any high spots on the plates and other such maladies.
