BMW E38 ABS DSC Brake Failure Repair 735i 740i 750i ↗

Why E38s throw ABS/DSC/brake lights that new wheel sensors don't cure: the hybrid circuit in the ABS controller fails. Options are BMW's repair 'black box' plus recoding, or a used unit from the exact same year/model so no coding is needed.

Tools mentioned: Diagnostic software (e.g. CarSoft), Torx bits
