I'm hoping someone can shed some light onto this for me.

I have a 330D, 55 plate which over the past 3 days has cut out whilst traveling between 60 - 80mph. I just seem to loose all acceleration, have to wack on the hazards and drift hoping nothing is going to whack me!.

Once the engine is off and key removed it starts perfectly but then feels lumpy, sluggish and unresponsive. Like it's suddenly having to think about what its doing and is suddenly carrying more weight if you know what I mean.

The first time it happened within minutes of each other, yesterday fine and car felt better then again today. Having to noticeably put my foot down harder to accelerate from roundabouts etc and seem to have lost the "head jolt" when putting foot to the floor.

Unfortunately, i was so focused on trying to stop safely that I failed to notice what rev counter was doing or if anything strange or any light appeared during the failure but nothing that caught my eye.

Any ideas?
