Vaccuum 0.0 bar readings on the trip computer

Normally I see 0.4 off throttle. Lift from highway speed, I get 0.3 lowest,
however I have on occasion noticed it will indicate low by about .2 bar
throughout the range. Car runs the same. Next time I drive it, it's back to
normal. Don't have a clue as to why.
