    The issue is the garage may fit a 2nd hand DMF or even a new DMF but not the rest of the clutch.

    So in 12 months or so when the clutch goes do you fit another DMF?

    If it lasts another year i'll be happy.
    I don't plan to keep the power of the engine standard with some mods coming after a year roughly.

    If i replace it after a year i can live with that, but i want to ensure i get good value for money out the standard clutch and DMF as well. Sachs organic clutch and Sachs DMF is £700 to buy without fitting so a bit too painful to be doing so soon after buying the car.

    I have a Mondeo ST TDCI (2.2 diesel) which has a right old noisy Thrust Bearing. Only makes a noise when the clutch is pressed, but once its fully down it stops.

    We priced it up, New Clutch, DMF & Slave Cylinder. One man quoted me £550 which was far too cheap as parts alone were £680 for the ST. The quote for the whole job came in at just over £900, which we could get Halfords to Price Match a local Clutch Centre who could do the work in one day. (Not Mr Clutch!)

    We calculated that if we had the work done immediately, it would take the purchase price up from £2000 to £3000 which was not good as the car had done 140,000miles.

    Its noW on 151,000miles and its still going strong. Still makes the noise and we still have the £1000 waiting on the DMF to fall apart.

    If it doesn't, we will eventually sell it for £2000 and hey presto..

    I've got an fr tdi. Now if i sold mine as private 1 month ago (2k miles) i'd be pretty annoyed if u came back and said you want money back because of clutch failure.

    Trade, you should have a standard warranty, but again its tricky and a lot can be done in 2,000 miles.

    It cost us £580 to change the clutch /flywheel over to a single flywheel clutch on our Octavia a year ago.

    It will rattle on for a long time. But how many starter motors will it kill in that time?

    My sister killed 2 starter motors with hers and the 3rd one fitted when replacing the clutch and DMF.

    So it cost her more in the end rather than fix it early and properly.

    If it kills a starter motor, i'll replace it straight away. Maybe it's just me being really picky about the noise, but i have no experience with DMF wear / failure to gauge if i have a problem, or i'm being pedantic. I've heard of SMF conversions as well for these, but after checking a few videos on youtube, they seem pretty noisy

    Apparently £320 from here for the whole kit for a Mondeo ST 2.2 TDCI, but google reviews said to stay well clear of them. Instead we looked at LUK parts from genuine part sellers (GSF etc). The labour was 7-8hours to get it out and back in... nice eh..

    Single Flywheel... Maybe in a Ford Transit Van. Never drove one, so cant comment.

    The single mass flywheel conversions seem to be good in the way that you'll never need to change the flywheel again, but at the cost of smoothness and quietness. It's a daily, so although i'm used to older diesels i'm going to stick with DMF for sure.

    There's a full Sachs performance kit with performance pressure plate as well, but that's £750 before fitting....

    The one i'll likely go for when it's needed is the one below though.

    One common bit of advice to prolong the life of a DMF is to have the clutch pedal depressed when starting and stopping the engine. (There was some detailed study showing that significant DMF wear occured at these time without depressing the clutch, but I can't find the link quickly, sorry.)

    As for SMF conversions, my concern would be whether this would be more likely to lead to a gearbox failure? Isn't part of the point of a DMF to protect the gearbox?
