Hi everyone,
I've retrofitted blind spot monitoring on my 2015 F11. The modules were from 2012.
After replacing the ZGM I initialized the flexray. The SWW module was visible in Rheingold, but there was no possibility to inject CAFD into it in ESYS.
I decided to try and update it to my car. The hardware ID was mismatched, AFAIR the first part matched the rest was 004 002 and expected was 005 001. I decided to try it anyway. The flash went well, the module is visible, it accepted the CAFD. And this is the part where all goes to hell.
There is one error code for both master and slave module:
ICM 480049 SWW interface: Signal invalid
SWW 481C92 SWW: internal control-unit fault
SWW 481C9A SWW: slave, internal fault
I found this topic where the OP had a similiar issue so I reckon those modules just won't work in my car:

The question is, how to revert the firmware in the module so the hardware ID would match again? I'd be able to sell the modules then, as they should work in the pre-LCI cars without issues.
I don't understand the mechanism of the SWW update, as physically those are 2 modules and logically it's just the HC2 - is the slave firmware passed on by the master?
Thanks in advance!
