I was impressed by the accuracy of the old passive version of the TPMS my e90 has. I got the warning light this morning and looked at all 4 wheels and tirers and they all looked fine. I checked the pressure and the right front was 3lbs off and the system picked it right up. just thought I'd share my experience.
