Hello all,

I'm not sure if this is in the correct section, please let me know if I need to move it. I just picked up a 2009 135i w/ iDrive and it is showing two codes in the DSC system; 5DD2 & 5DD0: "DSC Hydraulic Unit Adjustment (Valves)" on my foxwell nt520 pro.

I tried to calibrate the Steering Angle Sensor and then the DSC sensor in that order, but the codes are still there. From looking around on the forum, I think I might have performed that procedure in the wrong order. Should I try calibrating the DSC sensor first and then the Steering Angle Sensor?

The only noticeable symptoms are that the car is almost in limp mode at higher RPM's, but other than that everything else seems to be working great. Any input would be greatly appreciated.
