    Thanks for the write up.
    As usual I have trouble with the simple steps.
    My question is how do you remove the plugs without bitching them up?
    I put some pressure trying to just pull, but felt like I was about to snap them.

    EDIT: The plugs are fastened onto the grip... you just pop them off and then you can see the release which is on the back of the plugs.

    Mine quit a long time ago but I was not willing to pay the money for the replacement. Thanks for the write up I will get on this and let you know what I find.

    Is there any possibilities to repair the heater strip as i accidentally cut it while changing the grip on the throttle side...

    I resoldered the connections, and then tested with a multimeter... Current is definitely flowing through the grip, but it still isn't getting hot! The right side heats like a champ... I'm confused now. Any suggestions?

    Hey guys,

    I had the same issue so I decided to follow that step by step repair process. Guess what? It works again... Thx a lot for this awesome help. I'm keeping 250$ in my pocket :clap

    I would say that the hardest part was to roll out the grip to access the wires. For the rest, it was a piece of cake:rayof

    Worked for me. My left grip was intermittent. it looked ok. But I resoldered both joints and it works fine. I replaced the grips with aftermarket ones. nice soft dirtbike ones. I purchased 2 sets and used both RH grips. Used hair spray to glue them on. Super glue at the ends to seal. Then a little silicon to make sure no water gets onto the grip.

    I was a bit worried at first that the new ones were a bit thick. But they warmed my hands up fine. Will try them in the cold in a couple of weeks when I head south.

    Hi guys,

    It's me again.

    After several hours, my left grip went off again so I soldered back the connections... and again, it went off after a couple of hours...

    What's happening? any idea? vibration?

    The way I fixed it looks similar to the first pic (no monster globs :evil )

    Ok guys, I solved my problem...

    My connection was cut at the main connection so I had to solder deeper inside the grip to make it work. Now all is fine :)

    I can give you pics if someone needs...

    Thanks for the tips!!! My welds looked perfect, but after re-soldering them, heating was back on :)

    Thank you

    Sadly, this did not work for me. I have a 2009 F800GS, and the throttle side grip heater has become intermittent, trending towards complete failure. I performed this disassembly routine last night. My heater element and the wires feeding it showed continuity from the junction in the switch housing. My solder joints looked fine but since I'd put the effort in to get in there, I re-flowed them. It did not help.

    Time to study the wiring diagram and see what else is specific to the right grip & start testing for voltage.

    The left grip works fine. I find it interesting that pretty much everyone else on this thread had the left grip fail. I assumed that the moving part (throttle connection) would be the weak link, but apparently not.

    I was intrigued with BMW's wiring solution for getting power to the moving throttle grip, and that bar mounted switch cluster is a wonder of packaging, very nice.

    My "theory" on why it's usually the left grip that fails is that most folks mount, dismount, and put bike on and of center/side stand from the left side ... thereby putting a lot more manhandling on the left grip ...

    the grips have one (separate/individual) wire each going all the way back to the ZFE, and another going back to a ground point.

    the brown lead is to ground .... that's an easy check...........

    Did you check input voltages to both grips?

    I did try measuring resistance. And both sides seemed to match but the LH would not reliably heat.

    JR, I did a much more extensive testing job tonight. I have 12V all the way out to the solder points when the engine's on, pulsing on the one-dot setting and solid on the two dot like it should be. I opened up the left grip's switch housing, un-plugged the heater and measured resistance: 3ohms. On the right side where I'm having the problem, it's 5000ohms. I was measuring at the solder points on the right grip, so I re-melted them a couple times, sucked off the excess and re-checked, but each time the readings were the same. It's hard to see what could go wrong with heater its self, sealed up under the molded on grip it looks fine, although I did not peel the grip off all the way; I need to ride tomorrow so I gave up and put it all back together. Something in there is impeding the circuit though.

    I'm afraid I'll be buying a new grip assembly from BMW.

    Look at the 13 and up grips from BMW if you go that route, they changed them to a wrapped solid wire.

    Also, if you decide to forego the BMW brand and go with aftermarket, I installed a set of A'me heated grips on my friend Triumph XC and I was really impressed with them. If/when mine go out, I'll probably go that route.

    This is what he has on his bike, they have dirtbike ones too.

    If you are reading 5K ohms across the grip that is indeed your issue.
    Which is actually good IMHO as any other issue would be more expensive an difficult to resolve.... :freaky

    I'd peel the grip back ... and see if anything jumps out to you, but in the older models it is a "printed circuit" encased in a polyimide shell and can fracture and Im not sure you could fix it even if you saw the break...

    I've not seen one personally, but understand the newer design is a wire-resistance element which should be more robust....

    Just started to try and replace the rubber grip over the heating element of my 08 R1200R.
    I damaged the element on the right (throttle) side. Do you happen to have a right grip you would sell? If it needs re soldering, I can do that.

    Any chance of having a right (throttle) grip you would sell? I just damaged the element replacing the rubber grip.
