How to look after a dual mass flywheel?
Discussion
I've just had the DMF changed under warranty (thankfully) on our 2010 Hyundai Santa Fe with 50k miles. The list price of the part alone was £1600, and, as I anticipate keeping the car another 50-60K, I'm rather keen not to have to change it again.
Is there any general consensus on how to reduce wear on these things (or what sort of use tends to shorten or extend their life)?

Labouring in too high a gear.
Overloading by towing a heavy trailer.
Ignoring ignition problems such as misfires.
Remapping.
Hyanddry are taking the piddle with that price.Labouring in too high a gear.

Just had a 2008 Volvo V70 done for £960. DMF, clutch, bearing, new gearbox oil, labour and VAT. 250,000 miles.

The part they fitted may be a new and improved version, they're still trying to make DMFs which don't fall apart every 50k.
Avoid laboring the engine at low revvs- use revvs and run the gears longer so that you slot into the next gear up at slightly higher RPM. If you've slowed and need to move off again, downshift to the right gear.

If you dont run the engine, they'll last a very long time.
But the reality is they're st. They fail
Drive gently, engage drive via the clutch gently etc etc
No off/on throttle unnecessarily. Avoid anything that loads/unloads/loads/unloads etc the DMF.
But they're still st.
This ^ summed up don't drive like a tit ................ but yes it will still fail eventually But the reality is they're st. They fail

Drive it properly like a petrol engined vehicle. Rev it as you start from rest rather than just letting the clutch out and the torque taking it and it will last a long time.
The DMF failures are almost exclusively on diesels. There are lots of DMF on petrol vehicles that give little trouble. Admittedly it is the characteristics of the diesel engine that kills DMF but driving style can ameliorate failures to a great degree.

In the middle of changing one on an Astra 1.7cdti with 300,000km on it. It has gone really badly but with it covering 300,000km I think it's quite good.
I love em when they have totaly gone and the outer has spun round covering the bolt heads so you have to cut the Bstds off with a grinder especialy when it's one of those jobs where the box is still in the bay and you now have to drop the subframe to remove it to get the grinder in there

And they call it progress bloody things mind you I never liked clutches or gearbox replacement (auto or manual) as a job anyway this hasn't improved with age either especialy when it's one of those jobs where the box is still in the bay and you now have to drop the subframe to remove it to get the grinder in there
