the other day when driving i had a jerking movement for a couple of miles then had as plum of grey smoke about 200-300 yards down the road it cut out and would'nt start at all when to a friend who replaced the fuel filter and test drove it and told me he had it running without a hitch picked it up today and the problem is still there it cut out again no glow plug light comes on so he cant read the error codes , need help please

Ok firstly whats the millage and age of your car?
Secondly is it a tdci or tddi?

Have they actually tried plugging the computer into it? as its possible the bulb has blown for the mil light?

Thanks

Dave

The car is a 2litre TDDI it was plated in 2002 and has done 237 plus and had a new fuel pump when the mileage was 150 plus hope this is help full to you.

Ok

Is the turbo still giving a good boost when you put your foot down?

Is the oil and water level ok?? Is there gunk on the inside of the tad cap?

I think it might be the turbo but not 100%
