Do you mean quiescent current? Typical values are about 40 to 50 mA, cars with immobilizer (alarm), W210 for example up to 0.085 A.

Your figure is 10 times more than it should be (when the car has completely entered sleep state).

Perhaps the seat control unit issue, have you tried disconnecting the fuse?

I'm assuming one of the control boxes on the CAN-bus do not enter sleep properly and that keeps the CAN-bus live, making the OCP stay up (keeping the fan live too). The problem is that there are several devices connected to the same CAN-bus.

I would suggest reading/asking the W203 section, they would suggest the most likely unit. You can try unplugging a fuse at a time to see if the current draw goes away.

Been discussed here too:
