Since instrument cluster was in question, I had the cluster replaced since it was loosing pixels. Parts covered by BMW USA good will program, I paid labor. The error did not go away, so engine diagnostic showed DSC module error, electronics part. BMW would not cover the DSC module cost. I could have the DSC unit rebuilt, but that will put me out for a week and I need the car for prearranged business.

It turn out to be a VERY expensive repair. It could be worse without the BMW good will.
