front electronic module wrong hw version
Good evening guys.

Retrofitting xenon headlights to f20 pre lci.  Added grounds, changed some wiring and added 522 to fa and coded fem. Lights work except for headlight shutter, got an lwr error which I can't code out and got an error in i5тд saying that fem is wrong hw version. 

Could it be I need another fem to get high beams working?

It's the first time I encountered this error and I have no clue what to do.

Regards

Thanks for the info. I never changed one just for xenon conversion.

How can I know which fem to buy please?

Thanks.

FEM modules which supports Xenon lights should have a star ( * ) before BIX in line below рдят number, see examples:
