I`m working on e93 and I cannot get to the bottom of DSC issues. ISTA shows no reading from all 4 speed sensors, no reading from the steering wheel sensor also error in CAS module, and airbag error also.

Replaced the DSC with a working one (programmed & coded), replaced the SZL also and same results. I don`t know the history of the car.

Have anyone came across the same issue? Next step that I'm considering is to trace the wires that goes from DSC to CAS module.

This is usually the first suggestion from ista, To check all wiring and fuses. All three power fuses are OK and give battery voltage at the DSC plug? DSC should give wheel speed direct without intervention of any other ECU so start by ensuring power is reaching it AT CORRECT VOLTAGE. Also check that the sensor wires have integrity up to the sensor
