i have F26 X4 of 2014, original SZL not have FLA buttom, but have steering wheel heating function.

just have one damaged SZL from F25, have FLA buttom, but not have heating steering fuction...
i want mixed these two, and make one with all. It seemed easy but it's not like that

First, i solder handle/lever with FLA buttom from F25 in my original SZL. all ok. but FLA buttom not work.

PCB of these 2 SZL are identical. i looking configuration/programation of SZL are in eeprom ST  M95080
i try eeprom of F25 szl in my original SZL and work FLA, but not work Heating function.

the problem is eeprom reading is different...
if any one can help me, for mixing eeprom... I guess nobody tried this, it's weird. I'm afraid I'll have to buy a new SZL...

Yes, FA and all coding ecu, This part is ok. in Fseries SZL can not be coded, are integrated in JBE (Junction box module)

F26 ori SZL with FLA Stack taken from F25 and original EEProm F26. Work heating but Not work FLA Added buttom.
F26 ori SZL with FLA Stack taken from F25 with EEprom of F25. Not Work heating but work FLA buttom.


i think EEprom is configured from factory for Options, no way just by coding.
