Greetings, all!
In regards to BMWs equipped with the N47 2.0d engine, I would appreciate some guidance.
Here are the symptoms:
Idle engine runs harsh, causing the entire car to shake.
Pushing down on the gas pedal produces very little force.
A strong diesel odour becomes noticeable after approximately one minute of operation.
The ECU does not record any error codes.
Regardless of the temperature, the issue is clearly visible.
The engine isn't operating smoothly and feels feeble under acceleration, but the car still starts.
Injector overfueling or leakage could be the culprit, according to my investigation; yet, the absence of codes is surprising.
What are the questions?
Does it sound like a single negligent injector or maybe more than one?
Does a mechanical failure of an N47 injector result in the throwing of any codes?
Is it better to examine the injector correction values first or to do a leak-off test immediately?
Before I remove the injectors from the N47, are there any other typical reasons for this?
In ahead, I'm grateful.
