W220 window wierdness

[boomer]

All my windows work fine from the buttons, both on each door and the drivers door switches.
However, when I start the the engine the passenger window opens itself
Could it be a high resistance Canbus wire to the passenger door window controller?
If I have been driving for a while and shut off the car, then come back after a few minutes, it doesn't do it. Maybe i need a new car battery?

Could be door controller, or water somewhere, could be a SAM problem

Thanks Malcolm. Water is a possibility as is the SAM. I'll see about getting a spare SAM & window controller.

STAR would confirm which one is at fault
