116d running bad low load
Hi!
I have bougt a F20 116d 2,0 from dec. 2013, 150.000km, as defective. Diesel ran into engine-oil. Replaced hi-pressure-fuel-pump and that problem was solved. Engine starts fine, but has a lot of misfires when running at light load / steady speed. When engine is under load/accelerating it runs fine. Idling and rev'ing the enginge in neutral is fine too... No errors stored in EDU. It has some engine-knocking under load up to 12-1500rpm. When unplugging the air-mass-meter-sensor the engine without misfires - but still some knocking when it under load at low RPM's. Replaced the air-mass-meter, but still same problem. Do you have any idea? Last edited by Vezzel; 01-18-2020 at 03:26 AM.. |

I had to search how a diesel could misfire (there are no spark plugs). The first result has a list of suggestions as well: https://www.quora.com/What-is-the-ca...re-in-a-diesel.

Ok - I will try do describe it in another way - the ingine behaves like it does not fire on one or more cylinders for a split-seconds when driving at a steady speed. When the car is accellerating there is no problem...
