Everything goes through the module. It runs the pump, reports errors regarding the pump. It's not uncommon for the pump error to be the Achilles heel on this fault.
I hope BMW used a newer model for the e70. Wife and I switched to e70 over the past year I'll be very happy to never chase that particular strain of e53 herpes.
