Thousands & thousands of DMF’s have failed. I’ve read of solid replacements resulting in snapped cranks. Ask taxi drivers.
If buying a used Mondeo, look to see if its had a recent new starter motor. If it has, but the DMF hasn’t been done, it’ll likely be on its way out. (the magnets in the motor attract the metal particles from the failing flywheel).

this was also common in the transits, i have bought and sold a few, the dust gets into the starter motor or even on the shaft which ■■■■■ the starter up, in the past i have blown them out and then oiled the shaft and they have been ok, for how long i dont know, i have heard of folk lining the bell housing with thick grease to attract the dust in the past!
Certainly not all Mondeo’s have DMF’s - Mine doesn’t.
If your having problems with your clutch it could be the slave cyl.
My boy who is a mechanic/tech at a Ford main dealer says a s/m may cause excess vibration, that is what the d/m is there for to absorb the vibration and harshness
My MK3 Mondeo TDCi had a DMF. Was still on original clutch and DMF when I sold it at 175,000 miles.
Depends on how you drive them. If you do a lot of round town driving you’ll kill them quicker. Local taxi firm uses petrol cars because of that.

Why? When the solid flywheels of old didn’t?
Thing is, nothing’s changed with the engines or gearboxes, the new Mondeo 1.8 TDDi engine is the same 1.8 diesel engine that was fitted to Mk 4 ■■■■■■ vans! All they’ve done is taken an old design engine and slapped a common rail and engine management onto it.
So if the engine with a solid flywheel didn’t vibrate in the late 80’s, why would they vibrate now with a more refined fuelling system?
(we’re a ford dealership too

I’m sure you’re aware, when you buy pattern part starter motors for Transits, they come with a warning in the box, that the manufacturer won’t honour a warranty claim for a failed starter motor where the DMF is established as the cause of the failure.

Hi cieranc, you’re right, but I thought the 1.8TDDi Endura in the Mondeo/■■■■■■/Fiesta was superceded by the all new 2.0TDCi Duratorq Focus/Mondeo/Transit engine about 2001? (and much more troublesome than the TDDi it proved to be).
I should think that a lot of the problems come
From how they are driven, and particulary how high they rev, my transit does 35 mpg, and rarely revs over about 2000rpm, driven by a 74 yr old with all the time in the world, i have yet to see him go faster than 55mph, he is an ex truck driver and says thats about right for him !
The whole idea of dmf is cheap.Not for you for the manufacturer.
With dmf you can build a,shall we say,less rugged gearbox as the dmf is “supposed” to absorbe engine fluctuations at lower rpm so putting less load on the drive train.
Only problem with this idea is that the dmf then has to absorb these “fluctuations”
The clutch spinner plate costs about a quarter of a standard spinner as it has no shock springs built into the spinner hub and is realy just a bit of tin with friction lining glued on.
So really its about building a crap gearbox and a cheap ■■■■■■ clutch but the clever bit is that when you come to replace it they screw you for anything up to 1200 quid when once upon a time it would have cost you maybe an hundred!
And if you do fit a solid flywheel kit it puts load on the cheap crappy gearbox.
Change a full truck 700mm clutch(for parts) 400 quid change a 300mm dmf and clutch on some eurobox 800 quid? Then of course you got the concentric clutch slave for another 200 notes.
Bloody good con job if you can get away with it.
I had a vectra 1.9 150 and we welded the dual mass fly wheel up so it was in a solid one I cured rattle and ran perfect for the fifty thousand miles I had it
bit Of a job but saved lot of cash.
