    The company I work for runs twenty two Fiat Ducato 3litre mini buses with comfortmatic gearboxes,
    Max weight when loaded 4500 kilos. all built on maxi chassis.
    lots of problems with then but the biggest has been clutch related. most have had at least one replacement clutch some have had two. many of them have had clutch slave cylinder problems.
    one bus has had four slave cylinders. At present we have five buses off the road with clutch problems.
    Fiat have been very good with warranty haven't cost us anything so far but come the end of July that will all change.
    most of the buses have done between 30 to 60000 thousand miles and do approximately 20 stops picking up and dropping off per day.
    Our previous Iveco buses didn't require clutches till well over 100000 miles.

    Come the end of July there may be 22 minibuses up,for sale then.

    Can't run a fleet that size if the vehicles can't take the pace.

    Inherently dodgy clutches - a well known weakness with these.

    Clutches are a potential problem with any robotised clutch or manual 'box IMO because any smoothing of gear changes is done by slipping the clutch. Any attempt at rapid takeoff, for example, is defeated by the control ECU allowing excessive clutch slip.

    I am told that there is some sort of learning process in the software.

    The fleet of Mercedes ambulances that the Scottish Ambulance Service had with automated clutches didn't give a blink of trouble. I personally had a 2.7 wagon with this type of clutch which was eventually retired with over 400K on the clock & never had a clutch replaced! This was an "on-call' wagon which would sit outside with coating of ice & snow, started & then driven flat out within seconds. The Peugeot ambulance that they have now cannot go for a full week without a breakdown, the brakes catch fire, the clutches go & various suspension faults. The service are looking at scrapping them early due to poor reliability.

    Not just a problem with the auto version I think.
    My manual has had a tendency to slip when accelerating hard or on motorway hills with the cruise engaged for the last 10,000 miles, but I think it's the stupid dual mass flywheel rather than the clutch that slips. Every vehicle with a DMF that I've changed the clutch on has been the same, slips under high torque conditions but cannot get it to slip under "normal" clutch slip conditions, e.g trying to set off with brakes applied, driving onto ramps etc.etc. and all those clutches have looked serviceable when dismantled. I have replaced them with solid flywheel kits & they have done greater mileages than with the original clutches without problem.

    I think I am probably pushing my luck with this clutch / flywheel now as it is definitely getting worse, so trying to find more info about the 3 litre clutch / flywheel set up before I have to bite the bullet & replace something.
    Has any body fitted or had fitted a new clutch without replacing the DMF?

    Has any body fitted or had fitted a new DMF without a new clutch?

    Has anybody fitted or had fitted a Solid flywheel kit with the 3 litre engine?

    Hah! you obviously havn't found out yet that the clutch pedal on a Ducatto is made of plastic.

    I did in the middle of Dartmoor, no phone signal for bloody miles and miles and miles and miles and miles!

    Lots of pictures very much appreciated (y)

    Normal procedure is to quote for replacement clutch at near £1200. If on inspection the DMF looks to need replacing it is another £500 hit plus labour. It's a holiday fund program for greedy bar stewards
    LUK full clutch and DMF is under £500 total on ebay

    Wow so the £1100 I paid for a new DMF and clutch on a transit based van was quite cheap. The flywheel had seized covering the bolts and the holes had to be ground out to release the DMF
