Nope. It should not display any pressure with the engine off, ever.
If it indicates 5 bar with the ignition off, you have a wiring
problem, dash/gauge problem, or a failing sensor.

That is astonishingly high oil consumption for a 3B. Figure out where
it is going. If it's burning in the combustion chamber and leaving
deposits, you're artificially increasing the compression ratio and
'hot spots' for preignition. This is also a great way to kill off the
O2 sensor and the catalytic converters.
If you're filling it to the max line- don't. It's marked "maximum",
not "fill me to here" ;-) Half-way between min and max should be
plenty.

That's the correct behavior.
