Hi
I have a 407 sw 2.0 hdi 136 (auto 6 speed) (07 plate) (105k on clock)
Recently I had the thermostat replaced/front cooling fan and timing belt changed (this was due). Now about a week later I have been experiencing juddering/stuttering when driving at steady speed. This happens after 15 minutes of driving and the revs go down and some smoke from exhaust can be seen (not loads, just puffs). When accelerating it doesn’t automatically pick up but does after about 2 seconds and then ok when pulling but soon as you reduce to go steady then its jumpy revs go down like it’s about to stall but it doesn’t stall. On idle it’s ok and when accelerator is pressed a little nothing happens but smoke come from the exhaust. If pressed slightly harder it revs like it’s missed a beat and smoke clears. No engine light come on. This episode only happens once a week, otherwise the car drives perfectly and I think then wow its gone and I am loving it but then it haunts me again. Switch engine off and on makes the car ok but the problem is still there waiting. I have searched for solutions but unable to find anything which describes this type of scenario. Any help would be appreciated thanks
