Just got home in the car, and it sounds like its running on three cylinders, and won't rev above 2,500 revs, but theres no warning lights on.
Has anyone else experienced it?

Hi mate I have experienced the three cylinder type misfire and i think it happens when the engine is doing a serious dpf regen, the whole engine was moving like it wasn't balanced but after a while the revs drop back to idle. Not sure why it wouldn't rev over 2.5k but this could again be dpf related and maybe even in limp mode, but no warning lights is odd! Hope it sorts itself out.
Thanks for the reply mate, as I've been sat here for two hours hoping someone would reply. lol.
I think I sussed the revs thing is because it was stationary and not in gear. I tried to rev it to listen and look for smoke.
If it was doing a regen, should the regen/dpf light have come on???

There will be no visual sign from the dash that the car is doing a regen I can only tell when it idles at 1k or I can smell burning soot. Also the engine sounds like a bag of nails and it sometimes moves about on it's mounts. If it is doing a regen just let it see it's self out if you can, will take about 10 minutes when idling stationary.
Its a safety feature to stop you revving the nuts off the car i figure?
The engine mounts seem to be least effective at reducing vibrations (resontant frequency) at 1000rpm or there abouts, a bit of a design over-sight there seeing as the regen raises idle to 1000rpm too.

All sorted today. Its the first time I've experienced it doing that, and I wondered what the hell it was!
Thanks for the replies

I have never felt mine do a regen or had a dpf light after 5000 miles. But I do mostly motorway trips so it's probably doing it when im travelling at 70mph and i just dont notice.
Well after three months and 2700m I experienced my first DPF regen last night. Driving into the centre of Newcastle I stopped at a junction and thought my car was sh****d. The engine was so lumpy the whole car was shaking, then I noticed it was idling at 1000rpm and sussed what was going on. No burning smell though! I carried on with the journey and after about 10-15 minutes all was back to normal.
All in all it was a worrying few miutes till I worked it out, I am just pleased it wasn't the wife using the car at the time, she tends to panic a bit.
Just as an aside, I have noticed over the last week my fuel consunption has not been as good. It will be interesting to see if it goes back to normal now and if it was caused by the DPF being restricted.
