That gives me an unrealistically high number. I saw another post where he subtraced 1030 then multiplied. It must be right, can anyone tell me why?

Thanks

here's the math:

there are 14.5037 psi in 1 bar

there are 1000 millibar in 1 bar

so:

(1 millibar/1)(1bar/1000 millibar)(14.5037 psi/bar) = 0.0145 psi

hence 1millibar = 0.0145 psi

Perhaps you're reading the wrong block on the VAG, or are not reading in millibar?

I think you have to subtract 1000 from the VAG millibar reading for atmospheric pressure.

makes sense since atmospheric pressure is 1 bar = 1000 mbar.
