Dual Mass Flywheel Question

[Exeowner]

I recently read a comment on this forum (sorry, can't remember the thread) which suggested keeping the revs up a bit might extend the life of the clutch and/or DMF.

Not having had a car with a DMF before, I'm not familiar with what the life span of one is or how to drive in a way that suits it. I think the comment I read related to driving at very low revs for economy reasons.

As the VAG group CR engine is smooth and revs easily, it's easy to drive through the rev range and it doesn't seem to affect economy too much.

I'd be interested in anyone's thoughts on this, it seems a DMF replacement is very expensive on most cars, so I may as well adopt a good driving style from the start if it's a good idea.

Since the DMF is basically two fly wheels joined in the middle with a spring any type of excessive jerkyness (such as an engine operating under load at low revs) would, I suppose, put extra strain on it and could shorten its life expectency. I've not seen any conclusive proof of this - I'm just following a particular train of thought. From the experience of people I know (friends and family), the VAG range of TDI engines appears to suffer less DMF failures than their Ford equivalents - not a huge sample but of the 5 people I know with Diesel engined cars, 3 have Fords and 2 have VWs and all three Ford owners have had to have their DMFs replaced after about 5 years / 70,000 miles while the VWs are still going strong at a similar age and mileage.

I've looked at some DMF cutaway drawings and it seems such a simple device.

As the saying goes, 'What Could Possibly Go Wrong?'

Broken springs?

I plan to keep my car past the warranty expiring, I guess there's the option of extending the SEAT warranty if a failure was likely.

i'll agree with Ford's going early on, mate had one go at 33k.
i think it's luck of the draw if it goes?

i'm currently waiting for clutch on my '02 C5 to go, mechanic's not too sure whether DMF or not until it gets opened up, whichever it's got - unless i move it along - it still feels ok @ 228k

our last car was a ford 600 miles later the clutch went yeah bad one they put a new complete one in and sent the old off back to be tested, the new one lasted us and as far as i know still going, i have no worries with the exeo doing the same if it does not my problem

It’s always a gamble with certain car parts—some last, others don’t. Glad the new clutch held up well! While you're taking a break from car talk, you might enjoy exploring modded streaming apps like freecine apk for some entertainment.
