E91 320i cylinder #2 not working (N46 motor)
Hi all,

My 2006 E91, 320i N46 motor, started this morning without one cylinder working.
I have swopped coils, spark plugs, as well as injectors - but the same cylinder is still not working. Then I also traced the wire from the injector to the ECU and tested fine.

Can you please help me?!

Enjoy your day, Pieter

Did you clear the codes after replacement ?

Thank you for the reply. No I did not clear the codes. Can I do it myself?

No unless you know someone with a D-Can cable and some software.

If you in the East rand area, you can bring the ECU past so I can test for you. Coil failure on these motors are common, and at times they take out that channel on the ECU as well.

Well if you in a jam, you can always Postnet it to me. I have a jig here where i can properly test these specific ecus for full functionality. I should make a youtube vid of it one day and post on the group.

Yeah, but the risk is always that I make secret sauce available for competitors. Hence my reluctance to do it. There's no friends in this game.
