You could get one of these, Mr. Smarty Pants! Official BMW gauge measures official BMW air pressure. Bleed down the the correct tenth (use interpolation), per factory recommendation...
Notice stainless steel braided line, no extra charge!
I just quoted the owner's manual to be accurate and avoid being "corrected," as is typical. Looks like those numbers are conversions of 2.2 and 2.5 bar.
Since PV = nRT, one would assume the pressure should be adjusted according to each ambient temperature. As "T" increases, "n" must decrease and you push the bleeder button. If "T" goes down, the BMW goes down to the gas station for more "n."
