hi guys

as title really our Vec C estate CDTI 120 has developed a very intermittent judder/kangaroo on take off, ive noticed it only in 2nd gear, so rolling off in 1st, into 2nd, foot down and its like its hesatating then going, then hesitating, then going.

does anyone know what it could be?

i had the boost sensor out at the weekend and cleaned that out as it was all sooted up but problem is still there, the car had been run very low on fuel, could that have maybe pulled some silt through from the tank and caused it?

any advice is apreciated as im supposed to be driving down to Kent at the weekend.

thanks
