I'm sure that my TPMS doesn't know the actual pressure of the tyre as it just has normal dust caps on the valves. I think my TPMS uses the ABS / traction control monitoring sensors to see whether a wheel is going round more times than the others (a partially-deflated tyre will have a smaller circumference than a fully inflated one).
Current car: B9 S4 in MisanoRed, driver assistance, light & vision, advanced key, hill hold, heated front/rear seats, memory seats/mirrors, flat bottomed wheel, piano black inlays, rear view camera and rear side airbags.
Gone: B8 S4 in BrilliantRed with TechPackHigh, Adaptive Cruise Control, Rear Airbags & TPMS and also gone B8 A4 1.8TFSI SE
