Let us know how you end up fixing this.

Tangent: I once replaced a bad power steering pump with a used one. It eventually went bad as well. But it kept working (still had functioning power steering) but what the car would NOT do was it would NOT shut off. Turns out the power steering pump was backfeeding ignition system and the whole car even when the key was turned off and the key was removed... it would stay running as if the key were never turned off. Only way it was found was by unplugging stuff until the car shut off.

Maybe the pump I bought (rebuilt) is bad?
thanks

There is a 100 amp fusible link (FL4) in the engine compartment fuse box. The fusible link is on the bottom side of the fuse box (you need to flip the fuse box over to see the fuse).
There is another 30 amp fuse (F08) on the top side of the same fuse box that protects the power steering pump, cooling fan, and the heater - AC blower.

Do you have any stored codes? the pump motor? is only part of the electric steering system. It all has to be happy or it won’t work. Plus the manufactures don’t want lawsuits and are usually a little pissy about sharing all the information on it. You may have fixed it, but it has to be flashed into the vehicles memory, it is a bmw after all
