But if this is correct, how come your car operates when the wire is disconnected ?


Sorry if I said it wrong, Stuart, my BPS switch is absolutely top notch. I had to interrupt its current flow to get the car running again without that awful jerkiness. And with your car, it could be the same reason.

Uther has confirmed what I suspected that there are intentionally different switches.
Richard (+8Rich) said in this thread that his 2009 4/4 also had two switches. That one was still Euro4. Of course it might depend on the different programming of the software. The diagram above only shows that this switch can be used to influence the accelerator pedal value. And exactly this I notice very painfully as long as the circuit was closed. So again my question...why is it a NO version of the switch? To me it would make sense only the other way around and using a NC switch. Then, the brake would influence the accelerator pedal when needed during braking and not when driving.
Luddite, I am very sure that the brake lights do not go through the ECU but only through the fuses.
