BMW ABS Control Module – ABS DSC Warnings – E38 E39 X5
car year: 2000
car model: 528i Wagon
ABS,Brake and DSC warning lights were on for months. Had a mechanic test for the problem. After testing, speedo, and odometer and associated readouts and cruise became intermittent and eventually quit working. I replaced the ABS control module with a tested used one, that got the cruise and speedo working again.I then took it to a BMW dealer to reset and program the unit. But they could not get the ABS, Brake and DSC to correct, citing pressure sensor line fault and precharging pump possible.
I would first wonder if there is indeed a problem with the used replacement module. With this noted, you certainly could have a fault other than the control module …. even though this is the most common fault for the symptoms that you have had. We have also seen past problems with attempting to re-code used modules (re-coding the module from another car to the coding for your car). It may be that this module simply can not be properly re-programmed.
