Hi, I'm new here and wondered if anyone's come accross this fault before?
I have an issue with our older unmodified 4 motion 140 BHP 2.0 litre TDI Tiguan. The car has 63,000 miles. It accelerates fine, but when up to temperature occasionally misfires or hesitates while steadily cruising with foot on the accelerator pedal. It also does it while using cruise control, and sometimes even on deceleration, but not every time. A misfire happens perhaps once every 5 or 6 miles of motorway travel. I do realise an intermittent fault like this with no fault lights may be difficult to diagnose, and had the misfire been either on acceleration or load it would be more common and easier to find.
I'm pretty good with a spanner, but pretty hopeless on electronics, and suspect this might be the latter fault. A fault on the fly by wire accelerator?
