Hey Guys,

I have a 2013 F30 Activehybrid 3 and I’m running JB4 with it. I recently got my alternator changed by the dealership and have been riddled with problems since then. I’m getting a rough idle and the engine seems to be stalling while stationary. Also the car won’t rev past 2500 rpm due to forced upshift operation by the DME.

I’m getting the following 2 malfunctions currently on I-Drive.

1) Drivetrain Malfunction- Full Performance Not Available.
2) Auto Start Stop Permanently Disabled.

ISTA Diagnostics is showing the following codes.

CDBA27 Message (actual data charging electronics, 0x108) missing, receiver DME, transmitter EME
212601 Crankshaft starter generator: Automatic engine start-stop function (MSA) permanently deactivated.
220561 Emergency operation manager: Generator operation request due to DME fault
220567 Emergency operation manager: Request, power reduction, electrical coolant compressor due to DME fault
220564 Emergency operation manager: Request, electronic gearbox control forced upshift (strong) due to DME fault

The dealership that changed the alternator reached out to BMW Germany and they have identified the recently changed alternator as the source of the errors. They’ve sent a replacement Alternator which according to them is going to solve the issues. I’ll know in a couple of weeks when it arrives.

In the meantime, I’m seeking opinions on this forum on whether this seems to be truly an alternator issue or does there seem to be any other mechanical/electrical fault within.

I am getting suggestions to replace the water pump and thermostat, some are telling me to remove the JB4 completely as it may be interfering with DME communications over CAN BUS.

Any inputs would be highly appreciated.

Looks like the EME (E-Machine Electronics) is not sending out a frame the DME is expecting. Not sure why that would be the case, perhaps wrong level of starter/generator (I am assuming this is what you mean by alternator replacement) fitted? Fitting a replacement part makes sense if that's what BMW HQ told them to do. The symptoms you have sound like limp-mode ones when the EME is not behaving as expected.

Thanks for the input. I'll post an update once the alternator is replaced.

Hey man! Any update on your issue?! Literally have the same problem. From the same 2013 Active Hybrid to the exact codes you have and even the tune. Any idea on the issue? Been dealing with this problem for so long. The codes are saying something about a crankshaft starter generator. Any update on your issue?

Hello, has the situation improved after updating the generator?
I had the same problem with my AH3. I changed to a used generator, but the problem is still the same.
