Hi guys. I have an e34 525tds and she had a bit of a problem. I don't know the history of the problem because it was there when I got the car. but think I have it narrowed down to the potentiometer in the injection pump. The car starts easy enough and will idle but it hunts badly. When you are driving it will be fine most of the time but for no discernable reason sometimes the injection fault light will come on and I will lose power. Clutching and revving brings it back.
However it will often cut off at the lights or in traffic.
I'll read the codes this evening and post up what I get.
Has anyone had a similar fault?
I have checked the in tank delivery pump and it is working well. The car has not got massive miles on it but they aren't exactly worth a fortune so I want to avoid a new pump if possible
