Hello. First of all I hope I can type here in english. I have asked for other forums but without answer.
I have 04 e46 with m47 engine.
Problems are that engine runs very jerkly when idle. now few days ago I got my first limp mode when pressing harder on gas.
Went home and took my laptop with inpa and got:
4B11 (1279) Laufruheregler
3FD0 (1262) Luftmassenmesser
4560 (3002) raildruck-plausibilität nengengereflt
4A42 ews schnittstellenfehler
What do these codes mean? First one is something with smooth running controller? what is that? crack shaft sensor?
Seccond one is Air mass sensor, this one I know, had bad connection. now fixxed
3rd one is something with rail pressure?
and no idea what is EWS module error.
Also I have one more problem. When ide or light acceleration the car is fine, when I acceleration HARD then I hear knocking / pinking / ratteling sound from the engine bay. Is this injectors?
The sound stops littlebit before rev limiter, then changed gear and it starts again, as soon as I let go the gas pedal, the sound stops.
Here are injector values from inpa
First one is when Idle, seccond one is in park rev limiter.
I really hope someone can help me, been struggeling alot with this car and BMW is new world to me, I came from VAG
