If it's the pump, you can buy a used unit and separate the pump from the control unit and swap the pump onto your control unit.

If it's the control unit, you have to get a replacement (either new or used) and code it to the vehicle. Find someone who can code a used module before buying one. Not everyone can and dealerships rarely do coding on used parts. Especially a part that controls safety systems.

If you get your car scanned with a BMW specific scan tool, the DME will most likely have a specific fault stored for either the pump or control unit. This will tell you which is bad and you can go from there.
