    Low tire pressure light came on Thursday AM. I gave them the once-over and all looked fine, reset the indicator and waited till that night to check pressures - but I neglected it since I had tire rotation scheduled for Saturday.

    Had the tire rotation and checked and adjusted the pressures Saturday. it was warm when I parked it.

    Monday AM it's colder and the light comes on again. Another once over with no obvious reason and pressures checked out normal. Reset and head to work. Within a mile or two - the light comes on again. Ok - headed to tire dealer. They checked the tires with no obvious low pressure - but checked one that "looked like it might be the cause" but no leaks visible in the tub (thin it was the way the car was sitting on the uneven pavement).

    Reset again and on my way. At the first light, as i hit the brakes I noticed the pedal pulsing as if ABS was activated (but it was not hard enough or quick enough stopping to cause that) and then the light came on again.

    Now, i'm not THAT concerned that the low pressure light is on - but each time it comes on, so do the lights for DSC and ABS with mean they got disabled too, and that I don't like.

    At this point I'm suspecting that the problem isn't low tire pressure but rather one of the wheel speed sensors. So now I have to figure out which one...

    Ahh, the MINI Trifecta, in Land Rover world the same issue is known as the Three Amigos. The cause is different, though.

    Most likely a sensor.

    I get it when it is colder than 50F outside.

    Don't ask why, because I don't know the answer, but most of the time it is the front left speed sensor.

    I had this problem long ago and sure enough it was the front left.

    One of your wheel speed senors is dead.

    In the first gen cars the wheel speed sensors are used to guess at tire pressure for the indicator. The good news is that you don't have tire pressure sensor to deal with.

    Car makers are going back to using the abs sensors for TPMS. It'd great not having to deal with those darned TPMS valves stem things. Farking tire nanny's. :prrr:

    funny - the video series I found on replacing the sensor showed the guy replacing the left front sensor :) That series looked complete enough to back up the manual I've got.

    Strangely, after I cleared it yesterday, it has not come back. If it does I'll see if the scan gauge tells me which one it is.

    FWIW, I've had the trifecta several times over the past 160k-ish miles. I don't think I've ever actually needed to replace the sensor. In every case, I've pulled it out, cleaned the rust off it, unplugged it, cleaned the plug with contact cleaner, and reinstalled... and it worked fine for months or years, until it did it again.

    I had a retaining clip for one of my wheel speed sensors break and the cable rubbed on my tire causing the wires to cross circuit. I repaired it myself and didn't buy any parts. I had heat shrink, wire and electrical tape already. I zip tied my wires to the frame.

    Farking tire nanny's..... :lol::lol::lol::lol::lol::lol: Tell me about it.

    All because some crappy 2 door Ford Explorer Spots flipped over because of crappy Firestone tires low on air pressure now the whole world needs tire nanny's. WTF? :incazzato:

    We would never need this kind of tech crap if people would just check their tire pressure. Checking you oil world also help. Damn the world is so lazy now. :incazzato:
