I have a 2005 2.2 dci which has just reach 100,000 which feels like it has a misfire but a diesel, so far I have changed to the fuel filter, cleaned the k&n filter,cleaned the MAF sensor but not fixed the problem, my next plan is the try erg cleaner to see if that sorts it out it currently has a slightly rough idle, have watch the rev counter really closely and it does seem to raise but only very very slightly so it could be suction valve on its way out, car does feel slightly under powered, if I drive it it will skip along fine but if I have to stop off at the shops on way home and then restart the car it feels like something is stuck open or closed it just doesnt run correctly.

Cheers Ian

You could always take the EGR off then give it a clean and stick some injector cleaner in the tank to see if that helps.

I had a similar feeling of a missfire/ rough idle and it turned out to be the dual mass flywheel that had failed. The bearing in the middle of the DMF breaks up and it gets out of balance.

Easiest way of checking is to remove the crank sensor of the bottom of the bell housing and check for metal particles stuck to the sensor. If its covered, your DMF needs replacing..

This was on a 2005 dci with 108,000 miles, initially I thought it was the SCV so i replaced that with no luck then went and replaced the DMF and clutch.

Thanks for the replies, got a big can of erg cleaner which wont do it any harm to give it a good soaking, just ran through a can of BG244 and then a full tank of BP ultimate (would have used them together but the garage down the bottom has only just changed to BP normally run on Shell)

Will have a look at the sensor,now that I am thinking the clutch does have a bit of a judder when pulling away so it could 2 and 2 together,whats the going rate for a DMF and clutch fitted?(if it is that I can get a new rear crankshaft oil seal fitted at the same time,trying to look at it as a positive!)

so this morning I did a fuel pump relean before I took a trailer load of fire wood over to a mates place on the drive over it felt fine no miss or hesitation came back and took the crankshaft sensor out to have a look and see what that was like, it was fine maybe 2 bits of metal stuck to it so cleaned that up then took it for a test drive and it ran great,loads of power so came back changed the oil and filter and ran a can of erg through and it runs lovely so fingers crossed its going to continue running good as it was intermittent.

Additive in the Diesel to clean your injectors.
Works wonders as diesel fuel this year hasn't been the best due to cold weather
