What you gain by a Drexler non-active diff is predictability and also it doesn't generate as much heat as the Active M Diff, which is better fitting for continuous, high-endurance racing situations.
Since the Active M diff works in tandem with the DSC, decoding it would send the system in a fail-safe, limp mode.

jarringly, the car drives absolutely fine with the GHAS disconnected.
Unfortunately I still have the issue with programming the DSC to stop monitoring the GHAS as it only shows a communication error and a DSC error on the KOMBI & iDrive display.
I have looked at FDL coding but there is very little related to the GHAS in the DSC and ICM, it is also on communication with the ZGM but i highly doubt trying to program or FDL code the gateway will stop the DSC searching for the GHAS.
I have looked at FDL coding and VO removal, but there are no VO codes relating to the GHAS in the vehicle.
However, I am currently searching for a way to remove/delete modules in the SVT's and potentially look for a way to flash the DSC if required when the software is removed.
The search goes on and I will keep you all updated.
Edit: Unfortunately the M4 GTS FDL coding doesn't work either  |
Sorry you're still having an issue, the active LSD is spirt of an M car's handing and is part of integrated vehicle dynamics, so it's not surprising it's this hard to eliminate, it's almost like changing a major ingredient in a cake, if you know what I mean.
Just as how when a vehicle comes with Adaptive Suspension, it's a nightmare to eliminate for coilovers because they're tied to the steering and DSC software logic.
I listed a coding directory in my previous post that might identify the GHAS VO map, check it out, good luck and keep us updated.
