You say you replaced the steering gear box? Have you checked the servotronic? You can tell if you have one by looking at the steering gear box. There should be an electrical connector on it. If you see wires you most likely have it.

If the shop does not have BMW software I would recommend you find a shop that does. Aftermarket scanners cannot see that system. The signal is sent from the general module if I remember right. Servotronic is what "reduces" assist from power steering at higher speeds.

Good luck!
