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?
