hi , please can anyone enlighten me with the problem i have regarding my 2litre club dti on an 02 plate. The problem im having is after about 3 miles of starting my journey i loose power, the rev needle drops to 0 and when i stop the car revs up and down on its own accord,andtheres no pull away power. sometimes the power will kick back in to normal, i have been told this may cost up to £1100 to sort the problem, but i have been also told that the problem may be a sensor. i will be greatfull for any advice.
