Gents,

I am having the same problem with my memory seat module that many others have had. First symptom was intermittent steering wheel retraction. Second symptom was that the memory function for the seats failed, and would not be re-programmed. Finally, the seat has stopped moving.

I can hear the relays clicking, so power is getting to the module, and the switches are engaging the relays, but the current isn't being directed to the motors. I am wondering if this is a microcontroller problem, or if there is a failure point in the power side of the circuit.

Has anyone tracked down the circuit diagram for the e53 power seat memory module? That would help. If it is a software glitch, or a discrete component, I would prefer to fix/replace those than buy a new unit.

Thanks.
