170bhp tdi miss fire
Hi, has anyone experienced and corrected a miss fire on a tdi?
At about 2500 - 3,000 rpm and above I have a real problem with car holding back and becoming jerky & hesitant, the problem is there most of the time but is more noticable when engine under pressure. Tried different garages when filling up with diesel + additives but this hasn't worked. Driving the car below Ł2500 rpm no problems & no problems starting.
Thinking it maybe the fuel filter, please any ideas.
The car is A3 sportback Quattro, TDi 170 BHP, Oct 1996. Ł35,000 miles
