Dual mass flywheel noise

[sterion75]

Hi, more trouble. Can somebody explain the noise of a naff dmf please and a timing belt tensioner. I have one or the other going. Getting a dry squeal and rattle on start-up, gear change and switch off, also comes on over run if revving at standstill, Brad

Knackered DMF rattles like a bag of bolts!
Will do it on idle, but give it a slight rev increase and it will stop.... mine did anyway

Same for me, I had some vibration through the car also when you held the clutch.

It sounds awful, way different to any sort of bottom end or gearbox noise.

Eventually my clutch release bearing collar collapsed and the clutch wouldn't fully disengage.

Thanks guys,
my noise goes on lifting the revs jmkent but returns as you drop them again. Pretty sure now it is the flywheel as got it confirmed at our indy. He is quoting £800 fitted and eurocarparts can supply parts delivered at £418, local parts man at £523.87, both valeo. Spanners are getting dirty again by the look of it.

Fit a clutch kit and flywheel off a Peugeot Expert 1.6hdi. It is a solid flywheel conversion kit. No more DMF problems. £££ cheaper also.

That definitely sounds loose. See why they rattle. On the solid flywheel I can see why you would fit one but ive heard they can cause transmission failures due to insufficient damping. Question is if you have decided to keep the car would it be false economy. Has anyone had this conversion for long enough to tell if it was trouble free I wonder.

Me again,
how comes though the expert doesn't suffer the transmission probs; is their gearbox substantially stronger? Food for thought; or has their 1.6 a stronger crankshaft or different engine mapping.

Ive not seen or heard of anyone fitting a solid flywheel as yet so id stay clear of them personally. Besides the 407s DMF doesnt really seem to be that problematic compared to other marques. I think mine lasted 145k with 100k being more the norm

Hi sebasteeno, I tend to agree with you on this flywheel issue. I can get parts for £418, £168 more than solid, but in a few weeks the pain will ease. Time will tell if solid was best. Think its OE this time round though. Many thanks to you all for your replies to my original question, very interesting reading. Now for the painful bit.
