Hi Steven, thanks. If the BMW bomb does not supply the correct pressure (=53 Bar). An incorrect specked bomb (more or less Bar) might prevent the valve from (fully) opening or closing. This could be diagnosed as a faulty valve block. What do you think?
If I drive 60 km\h and turn off the ignition and do a panic stop, I can easily stop the car (feel assistance) and able to lock the wheels with not much effort. Can I assume the bomb is depressurized after such event and of course if I don't start the engine again?
Problem is I can't get me a rock hard pedal (with the bomb test) but I do have plenty power assistance when the engine is switched off while driving.
The latter tells me the bomb is pressurized and OK, the first tells me it's a) so good a bomb, it needs 70+ applications, or b) a sticking valve block prevents depressurizing the bomb. In both cases a) and b) this tells me the bomb is pressured and dangerous to remove.

I suspect that the valve that fills the bomb is not opening, and that is why there
is a hard pedal from the start. The system depends on that pressure
built up in the bomb.
