    Had limp mode twice - took it to the dealer and they replaced the throttle tube

    Just had it happen again two times in a row. This time I played with the GS911 and got the below fault codes and information. Anyone have any ideas as to what to check?

    This really makes me more than a little PO'd because I had similar issues with my HD Street Glide and after a year of futzing around with it they ended up replacing the wiring harness (and every other electrical component while blaming me for putting on pipes!)

    Any help is appreciated!

    So you are saying that they replace the throttle tube ? Is that the RH actual "throttle" twist grip assembly ?
    You saw my comments in the other thread, ..... ain't life grand ? Sorry to hear someone else is having similar problems.....

    Yep that’s what I remember them saying they were replacing.

    It appears that your left #2 throttle position sensor is showing multiple errors, this is now built-into the throttle body (Throttle Valve) so the entire $700 TB probably needs to be replaced provided the electrical connectors are solid.
    This is a somewhat common problem I'm surprised the dealer misdiagnosed it.

    The clutch switch error I wouldn't worry about that appears to be the result of you possibly coasting with the clutch pulled in.

    I don't know , I think I am going backwards toward "low tech" bikes if this BS persists...... technology is great, WHEN IT WORKS ............

    Same error code as mine, throttle valve 2 (left).

    Dealer replaced throttle assembly, no problems since. But then, it took near 17k miles for it to show up the first time, and then another 2-3k for it to show up the second before they replaced the throttle valve assembly.

    Frustrating that this is still present on the 2018 bikes.

    well the software update didn't do the trick, so I'm back on the phone with BMW....... ain't life grand ?
    Bike is under warranty for 2 more years or 35,300 more miles---- this could go on for a while ?

    next order:
    • check all connections ( I checked the connector into the throttle) unplugged it and plugged it back in a couple of times -seems solid - if there are any bent terminals in it, I don't know how you'd be able to see that, short of removing the entire assembly and the wiring to the throttle, laying it up on the work bench and inspecting with a magnifying glass.....
    • check for air/vac leaks
    • replace throttle twist grip
    • replace TB itself ?
    • Repalce wiring harness ?
    • Did I miss anything ?

    Ask your dealership to open a PUMA case.

    Inquiring minds want to know what a PUMA case is...

    A PUMA case is a internal support case between the dealership techs and BMW engineers. PuMA is a worldwide BMW database of all reported problems and most with the their appropriate fixes. I think the acronym means Problem and Measures management Aftersales.

    BMW will direct the tech on what to do and provide a higher level of diagnostic aide to the tech. If BMW Motorrad operates similar to BMW cars, the dealership techs have a specific process to run in diagnosing issues. Example: If X is present, run test 1, if not run test 2. If test 1 results in option 1 or 2, Fix A, if test 1 results in option 3 fix B. However sometimes issues do not follow prescribed test cases and need a higher level of diagnostic capability, thus the PUMA cases come in.


    EDIT: Added in what PuMA actually is.

    they already opened a PuMA case on mine. I don't have the number of it, but they did. I could call and ask. BMW told them that if the software was at factory original setting, that they need to update it first, before doing anything else. I called them this morning and advised them of the problem still being present. Sevice manager says he will email BMW again, see what their next move suggestion is...... tick tock tick tock. ... here I go again.

    That is very much in line with what is to be expected. It is a stepping process.

    I had the same problem with the throttle but never got to see the error data.
    Every now and then the bike would go to limp mode until I switchrf it off and started it again. Sometimes i had to do this several times.
    Sometimes the warning apeared when moving the handlebars in my case. I also got to record it:


    The problem was on the throttle wiring. BMW changed the hole wiring of the bike under guarantee. It never happened again.
    Good luck

    I sure do ! Seems like yesterday...... ah, the good old days..... 85 HP, no ESA, no DTC, No Ride Modes, No keyless ride, No Nav, ..... just Ohlins shocks, ABS, and lots of good days in the saddle....... LOL
    About that "85 HP" ....... i have to say , I do like the 125 HP of the new bikes..... except when it is "limp mode" , and it feels like about 3 HP, it's great !!!!! How you doing, Rocky?

    I retired at the end of last year and just started working part time at my dealer... 3 days a week for something to do. Needless to say, my cost for a new bike is, well, spectacular, but no desire, yet, to step up a WC bike. My Camhead GS serves me just fine. :-)

    Have had the "limp mode" issue on my '16 GSA for quite a while, GS-911 fault codes were very similar to those posted. Replacing throttle body does NOT fix it. Hansen's BMW in Oregon replaced mine halfway thru a month-long trip, and it happened again the next day.

    After wrangling with my local dealer, got most recent S/W update, and it hasn't happened again...yet. It is an infuriating situation. Just look: there are now THREE threads on the front page of GSpot dealing with "limp mode."

    And it is VERY unsafe...it if happened to me in very hilly country, I'd still be there.
