I have the 4x4 error in the cluster and also hints of DSC problem.

I also don't have ISTA. I used a Foxwell reader and attempted to clear codes. They wouldn't go away. Only after turn off and then restart did they go away.

I also had the parking brake light come on. I have rebuilt the parking brake actuator about 1.5 years ago and it has been mint since. After getting codes to not come back, i tested parking brake and it engaged properly and then released when requested.

I do not know if I have active steering.

2013 X5D, last 7 of VIN 0B95550 if anyone wants to show me if I have active steering. 140,XXX miles Thanks
