I am sorry, I know this has been done to death on here - but after a lot of searching I just can't find an answer.
Basically, I picked up my 1.9JTDm 159 last weekend, and things seemed to be going great... however it's picked up a few quirks in the past couple of days.
At idle, when warming up, the engine hunts fairly badly, varying between 850-950rpm, once every second of two. Also, when driving along, at around about the 1,500rpm mark, the car will misfire and lose power (seems to be worse in top gears).
I checked on FES, and it is reporting that the DPF is 106% clogged and its been 850km since the last regen?! However DPF state is 'normal clogging'!
I do a good motorway trip to and from work everyday (30 miles each stretch) so I would have thought it would have regen'd itself by now?
Also, I cleaned out the MAP sensor today which was horrendous, and took the EGR valve off but it was brand new.
Any ideas what could be causing this? For a car I have only owned three days, it sucks
