Done - ask me anything.

Just joined and wanted to chime in here since this thread helped me out in doing an esys-only RWD conversion.
Disclaimer: I have an iDrive8 G42 (2023). I know nothing about the F series.

Can somebody explain how to disable Xdrive with Esys? Would be totally great.

In my case, my car has an XDrive and RWD variant. I was able to edit my VO's typeschlussel to be that of a RWD variant. Then generate NCDs for the DSC_BRS and DSC_VIP_IB4. In my car doing both of these are important. Doing only one causes errors yielding a "Drive Carefully. Chassis Stabilization." message; and also hurts the integrity of the physics calculations the DSC algorithms use. All in all about 50-70 settings are different.

In what I presume to be an "Undefined Parameter" in ProTool, there is a series of hex bytes that represent your typeschlussel in ASCII. This is likely one of the things that results in the "Coding not valid for AWD vehicle." error I was getting while trying to do this all by hand.

The DSC_BRS module is protected with certain signature validations (??) on the SWFL/SWFK which I'm assuming are similar to locking my DME. Beware, you're probably blowing e-fuses and forget about your entire warranty when doing this. "For real, real." Assume it's gone. Period.

Simple... You cannot

Ok. Over 12 years it was not possible with ESYS or whatever’and coding.
Now the experts found the coding option.

I've swapped XD/RWD three times and I've driven (HARD) every day in exclusively RWD config for the last ~month.
In all three DSC modes. Rain, shine, dry, snow, subzero.
Zero errors, codes, or warnings:



I am not even an expert. I had about two days of coding experience to make this happen.

Please be more respectful.......   

Yes it is the same , that bdc body options doesnt really matter

Confirmed: G42 XDrive -> G42 RWD does not require any further changes outside of DSC and Virtual Integration modules. There is an option in the ZF 8HP-51 for AWD and I don't notice an effect with/without it. Perhaps a torque limiting system to keep axles from snapping...?



Cheers.
