I Slightly disagree......I'm not saying your completly wrong as the DMFs were developed to eliminate vibration etc. So vibration will be absorbed elsewhere i,e Drivetrain components....

But why "catastrophic clutch failures repeatedly" i.e 110Hdi engine... One in a Xsara non DMF and the other a 406 with a DMF. Yes Ones Pug ones a Citroen but same thing... Do Xsaras suffer catastrophic clutch failure repeatedly.... Same motor, difference being one is DMF'd one is isnt.

And why are manufacturers swapping dead DMFs to Singles?.... i.e VW Skoda etc...

As Ive said the DPFs can be eliminated... So no real end of the world stuff there. But do DMFs really warrant all the "Dont buy a Diesel"... "You'll be sorry when the DMF dies" etc replies to various threads.... I've already quoted what I could save fuel wise with my current commute... £1.5k a year with a Diesel over a Petrol.... So Even allowing for a DMF yearly and paying someone else to do the job...*that wouldn't happen btw*... I'd argue I'd have change.

And... theres a fair few clued up posters on here.....And many many many more that think they are... But does anyone have any views on what actually causes the death of a DMF... Seeing as timescales/mileages at which they die vary somewhat....

A good question indeed, and one I'm going to research tomorrow! I know what although in some cases DMFs are swtiched to a standard solid flywheel, but this is normally on the grounds of cost or customer preference rather than a strict technical update.

One thing I can tell you though, looking at the 406 as a case in point, the DMF version has a different gearbox (BE4R vs ML5T) with a different engine/gearbox mounting arrangement.

More tomorrow!

I thought they were on optional extra, as on Volvo's?

Interesting... I've not actually compared 406/Xsara like for like in detail such as that..... Or have you compared the 406 as 406DMF/406Non DMF... Non DMFs are 90s where I'm 99.9 sure all the 406 110s were DMF'd.

See I've seen them seize and I've seen them grenade themselves aswell... I've seen originals last decent mileage... and I've seen them die a premature death...

Will look forward to what you find out;)...
