    Interested to now if this is a problem, or a standard feature of the bike.

    I've had this bike a couple of months now, and i ride it rain or shine, hot or cold. I have noticed that I stall it at at the lights, and then i go to put on the heated grips later in the ride, nothing happens, as in no heat.

    The only way to get the grips going again, is to turn the key all the way off, remove it, restart the bike.... and then the grips work once more.

    Its only happened a few times, so i am not sure if the stall is whats tripping them up (the grips were not on when i stalled the bike), or if the key out and restart is the solution, or if its somthing else entirely.

    Normal? Warranty?

    LOL! Sounds like you do in fact hate them a little. :)


    Seriously though, not sure if it's normal or not. I suppose the system was designed to cut off power to the grips the moment the engine shuts down in order to not drain the battery. Maybe there is a bug in the software that does not bring the power back to the grips when you restart the engine unless you take the key out completely. Seeing all the hoops one has to jump through to get a battery tender to work with this CAN-BUS system, I wouldn't be surprised if that's how BMW programmed it. It should be easy enough to test.

    It's certainly worth asking your service department, although they'll probably just say that it's a feature. :)

    I could see if they were on when you stalled it and they don't come back on as maybe some sort of battery saver but if they were'nt on and now don't work seems like a glitch. You might find other things don't work also in this situation .

    You jumped through hoops to connect a battery tender? Just connect it to the battery.

    Well, I was trying to not have to do that and connected it through the power port.

    "Jumping through hoops" was an exageration of course, but you have to follow a specific sequence which involves inserting and removing the key to get it continue charging.

    It is likely that you have a circuit break or , less likely, a short.
    The can bus has no fuses. When it detects a fault with the hot grips it will disable them. Then automatically reset next time you start the bike. This is normal behaviour.

    If you bike shop checks the logs, or if you had a GS-911, you would find errors for the hot grips.

    Probably a dry solder joint at the heating pad. I had the same symptom. There are a couple of threads here somewhere showing how to fix it. The repair works fine.

    Check if it is just one grip, or both. If it is both then might be a different issue.

    I have a battery tender, and that is direct to the battery.

    To clarify, the heated grips are not on, stall it....by accident....restart without turning the key, ride to work and later one gets chilly fingers, turns on the grips, and naff all happens.

    One gets to work, fuming and cursing the thing. Takes the key out, re-starts the bike to make sure, and within 3 seconds, glorious heat is permeating said grips that 5 minutes before froze my hands off.

    If it were one grip alone, i would say glitch. Both, i say feature that is unexpected at first, and now a known royal pain in the fingers.

    Question was, has anyone else ever noticed it?

    I don't "think" that is normal, having to remove the key just does not sound right.

    If it were mine I would check to see if you get the same scenario other ways, such as hitting the kill switch or putting down the kick stand when in gear.

    All switching goes through the computer. I suspect it is a glitch in the programing since you lose heat in both grips. I had some instrument gauge malfunctions and it took a reflash of the ZFE to correct it.

    If stalling is an issue for you, gearing it to F800 specs or enriching the low speed fuel mixture with a Booster Plug will make it better.

    Stalling it is not an issue normally and i have only done it a few times in city traffic when someone wants to turn left from the lights with no indication and i am behind them, or some simple benign reason. That and getting used to this bikes throttle and responses. I have killed it a few times by putting it in first gear with the stand down, but I dont use the kill switch to turn off the bike normally, but... anyway...to the issue.
    Yesterday on the way home, no satlling or killing it it anyway, i had no heat. Time to make an appointment.
    Thanks for your help and input.
