I thought I'd reply just because my name is so similar to yours! [8D]
I get similar problems if a passenger moves the front passenger seat all the way to the back. I can't remember the error messages but one refers to CANBus, and another to wiring. I have to tell the passenger to move the seat forward 1 notch, and they just look at me confused.
That is of course if the car likes the look of the passenger, and actually unlocks the passenger door for them. B)
