I don't know, I'm probably overthinking things as usual, but..

I can get on board with the idea that when the engine is running it actually uses the hydraulic brakes as the parking brake...

But it sure feels like when I turn the engine off, they release, and the auto Transmission's parking pawl stops the movement that I encounter...

I mean why wouldn't it engage the mechanical parking brake before releasing the hydraulic pressure, if that is in fact how the system works..

And if it is, I wouldn't expect there to be any movement after turning off the engine..

Anyone else curious enough to test the behavior of their e70 when setting the parking brake?

Proposed test procedure:

Stop on Hill...
Engage Parking brake..
Remove Foot from Brake..
Place Transmission in Park..
Turn off the engine..
