    I haven't seen an ABS fault do that. Why do you suspect the ABS? Any other symptoms?

    Think you need too looks elsewhere for the fault causing the limp mode....
    Limp mode usually comes from an engine management issue....the engine computer says it doesn't understand... And limpmode keeps the engine running enough to get to a safe spot to shutdown....
    Bad abs sensors, or a computer can set a check engine light,or a code...but pretty sure no triggering of limp mode.

    all my problems started at once
    havnt driven it since oct 15 still love but need to sort it now
    Had a couple of instances of EML light plus limp but they cleared on restart so did nothing
    then had what they call trifecta
    so
    ABS light
    tpms light
    traction light
    but also
    EML and limp mode `
    Read codes and they were all communication faults stored in ABS Ecu
    so i thought maybe ABS not communicating but the ECU companies that do repairs thought unit was ok
    thought it might be an ABS sensor so was trying to replace passenger front when it snapped off.
    i was trying to find out if this could be linked or if 2 separate faults
    the EML is what i want to sort first :mad2::mad2:

    The EML is probably not the wheel speed sensor / ABS. Trifecta is probably wheel speed sensor, as you suggest, rarely do the ABS modules cause any problems.

    For the limp mode, most likely culprit is crank pulley failing, it's a two part pulley with rubber connecting the halves. When they get old the rubber tears and the pulley can turn somewhat independently, which causes supercharger and alternator to not turn at the expected speed, and the ECU complains with EML and limp.

    BUT there are quite a few other things that can cause limp mode. Someone who knows MINIs really needs to inspect carefully to further diagnose.

    Funny that had a new alternator last year
    Can you see if the pulley is breaking up?, also seems it could be Throttle or engine loom just suggest away

    Someone with a proper BMW-aware scan tool should be able to pinpoint it, quickly.

    limp mode can be caused by anything. On my Tundra I it was a silly pair pump needed for cold starts only. I can see how a manufacturer could argue that a bad ABS unit is reason to slow you down until fixed. Actually, makes more sense than the silly air pump in my truck that does nothing more than add fresh air to the same stinky exhaust the truck has without it, just creating (cheating) to get you better parts per million in a test. Bad ABS system could actually cause injury and law suit/

    Go get a generic code scanner from O'Reilleys or similar car parts store to get the codes. Have you tried resetting with battery disconnect reconnect?

    Whats confusing is you get trifecta lights because of ABS fault thats ok i get that
    you then drive a few feet forward and the EML light comes on and LIMP mode
    I can understand why no one else has had this problem

    And what I'm saying is, every time I've seen limp mode, there have been OTHER errors reported by the DME or other modules, that explained it. These don't usually appear as OBD-II codes. So the BMW-specific scan tools can interrogate ALL the modules on the car and report exactly what they're seeing. Maybe the Autel can go that deep, I don't know.

    Just remember too seek "professional help" ......always makes me wonder what type of a pro!!:lol:


    And to the OP...You have TWO or more issues....
    One is the abs/wheel speed sensors issues....
    Another is a an engine issue....you just happen to have them at the same time....but fact is a car with a failed wheel speed sensors, pump, etc is drivable...you can yank the fuse for the system....heck...folks have done it for track cars....the "trifecta" is annoying....but more is going on.
