citrophile Posted September 28, 2012 Posted September 28, 2012 Hi All Am just wondering if the following symptoms suggest that the DMF on my 2.0HDI 138 has gone south.... 1. When idling there is a metallic rumbling/drumming noise from the back of the engine bay which doesn't seem to affect the idling of the engine2. When I dip the clutch the engine revs falter slightly and there is a noise which in previous cars was related to a dodgy release bearing3. When I select any gear I get a horrendous whirring noise (and it's difficult to engage the gears) and the engine speed drops off to the point of almost stalling4. Significant vibration on take up when first pulling away (nightmare in stop start traffic!)5. Lumpy engine vibration when switching off6. Heavy clutch pedal.7. It was a bit noisy before but has got considerably worse in the past few hundred miles (fine on motorways but difficult to drive around town)8. I'm not getting any clutch slip but it almost feels like the clutch isn't disengaging from the engine completely Cheers Rob Quote
paul.h Posted September 29, 2012 Posted September 29, 2012 Sounds like a clutch problem but the dmf may or not be adding to it. It seems to be recommended to replace the dmf anyway when the clutch is replaced. You could always try bleeding the clutch but this may not help. Quote

paul.h Posted September 30, 2012 Posted September 30, 2012 (edited) citrophile Rob has his footer with 2 C5s as year 2005 so I suspect it is one of those and will have a dmf. Edited September 30, 2012 by paul.h Quote
citrophile Posted October 1, 2012 Author Posted October 1, 2012 You're right Paul, it's the 2005 Exclusive, the VTR is a non-runner at the moment due to a failed suspension pump (will revisit that issue another time!). Anyhow, took out the air cleaner etc over the weekend to get at the clutch slave cylinder and mechanism and it seems fine as it travels as much as it can in the bell housing aperture. It seems to me that it doesn't fully disengage so maybe the pressure plate is not releasing completely either. I've heard that they have some sort of built in automatic adjustment mechanism within the pressure plate itself so wonder if that has failed. Rob Quote
DaveHerns Posted October 7, 2012 Posted October 7, 2012 I think the automatic adjustment operates when the clutch is installed .Looks like you need to get the gearbox out for a look at the clutch Quote
