    Two warnings came up on my VDS today - it indicated tires too hot; then: check right rear pressure. Thing is, I was stuck in traffic, never got above 40 mph the whole trip (bummer). The actual pressure when I came to a stoplight and could access the tire pressures/temps, they seemed reasonably within range to me: 32 psi in front, 42 psi rear, and 98 and 104 respectively for temperatures. Surely this shouldn't have triggered a warning? Certainly I've driven faster in hotter temperatures, though admittedly I've never pulled over to check temps/pressures. Then again, I don't know what the trigger points for these warnings are. Does anyone here know? TIA!

    None of those temps/pressures seem über-abnormal.

    I've been having issues with my Roadster PEM getting over-warm (it's at the Tyco Service Center now, getting checked out). But, I've only had one moment where it actually got so warm that I got a "too damn hot" warning on the VDS, and the dreaded "Power Limit" light on the dash...and that was sitting in dead-stop traffic on I-66 this past weekend.

    And, while it may not be the best idea in the world (and I don't do it very often), I have found that I can just barely pull up on the parking brake (to the first notch) without the e-brake dragging...and it's enough to let me pull up the TPMS screen (after I clear the "Hey, dummy, the parking brake is on" alert).

    It's OVMS time ;-)
    That's probably the most useful thing I've use regularly in OVMS: checking tires temp & pressure in traffic (saves on pulling the handbrake while driving!)...
    Because I did have a faulty TPMS sensor which could very well be what Sethr is experiencing!

    I've got OVMS but, that would mean digging my phone out of my pocket and using it while driving...which is against the law (but, so is speeding).
