I've had my car for overs a year and it's been fine until today, coming home from work I noticed it was lumpy and rough at low revs, then when I accelerated from 1200 revs in 4th it gave a few puffs of blue smoke, but accelerated normally. When I stopped at some traffic lights the revs stayed at 1000 ish. After I gave it a but of a kicking it appeared to be fine.
Is this a problem or just one of the symptoms of DPF regen? I've never noticed it puffing smoke before during this process.
