I agree, that is the downside of the ABS-based systems. Does anyone know if the ABS-based in the 2011's can tell you which tire is low? Seems that should be easy to program if you're using ABS sensors.If all the tires had the same pressure, theoretically, they would all loose the same amount with a temperature change, and the ABS based TPMS on the 2011's would not indicate a problem, so a manual pressure check with seasonal temperature changes is probably prudent.
Yes that would be easy enough to program but its not really critical which tyre as you generally check all tyres if the light comes on. I've had my light on 3 times in the last 4 months and one tyre is 33psi when all the others are 37psi. Its the same tyre each time I've checked for any objects and nothing shows so it must be a slow rim seal.Does anyone know if the ABS-based in the 2011's can tell you which tire is low?
