The dreaded Error 16 code
@stinkyface Looks like that might be the case if the fault is following the controller. I assumed with how chunky those connections were they’d be fine but I guess after extended thrashing those are susceptible too.

@HanahsDax , I have no input on the technical troubles ... but sure hope it sorts out quickly and surely. So glad for the tips and comments from this site's steady contributors and experts!
@Lia Yeah I didn’t see any cracks or separation of the solder on the connection pins for the battery. I took a soldering iron and reheated them just in case. Still no luck. Looks like the XR streak will end as time is running out.
@HanahsDax Crap, only thing I can suggest now is to probe between the small white connector where the blue, black, green and white wires BMS side and with the controller side connector hooked up test the continuity all the way to the pins on the controller PCB to truly make sure that there is a path from BMS to controller and we're not missing something like heavy contact resistance in the connector.
If those are still clear maybe test shorts by probing between pins in diode mode, none of the voltage ones but namely white, green and ground. A shorted green and white (RX/TX) would confuse communication. I can't imagine the actual controller bit the dust!
Really sorry this happened, I'm hoping the solution reveals itself before 12.

Onewheel Legend you are!!!
@blkwalnutgrwr I second this, still #1 in my books.
Heatbreaking to see a HW issue do this, are there any 3rd party repair shops nearby that can take a look to get that board back rolling again?
@HanahsDax -- Your streak of daily riding continues unbroken with your V1 -- the two streaks overlap as you head for 1000 consecutive days riding Onewheels, even through Colorado winters!
Thanks everyone for the support, suggestions, guidance and kind words. The community has been great and a big reason I’m so bummed is I feel I’m letting everyone down by not being able to continue to push the next rider. This community is inspiring in so many ways.
I had two options yesterday, crawl in a bottle and let sadness and disappointment run my life or try my hardest to get my XR repaired while also still keeping the V1 streak alive. I was unsuccessful on the repair as I lack the brain power that was required to properly diagnose and repair but kept the V1 day streak going. The quest for a 1000 days in a row is now relied on continuing the V1 day streak over the next 97 days. I also still have 3 badges to collect to complete the entire achievement section of the app.
*Life is only as good as the memories we make. And when this hourglass has filtered out its final grain of sand I’ll raise my glass to the memories we had.
So long, Astoria-The Ataris/Kris Roe
@HanahsDax I think it's safe to say you've been an inspiration to us all and still will even without the streak. The streak is by far an impressive achievement, one to stay recognised for a long time however your presence in the community is something that will never disappear. Supportive, constructive and an all round gem of a character that I'm glad I can call a friend.
The V1 streak will carry the torch for now. Who's to say you can't keep pushing the next riders on the board everyone least expects to outdo them ;)
Keep us updated on your XR too, if you need to bounce any thoughts or findings off me I'm happy to continue assisting where possible.
@Lia Thanks for all your help and kindness. I wish international shipping costs weren’t so extreme or I would send the controller and spare battery pack to you to tinker with. I thought about sending it back to the mothership but they will probably just tell me I need a complete overhaul so it’s almost more cost effective to buy a new XR. I have a ton of spare parts I collected hoping I would be able to address any problem I encountered during the streak but I may put them up for sale and use the funds to help with new board cost. I think @blkwalnutgrwr wants a few.
@HanahsDax Agreed, international shipping bites :/
If nobody more local could take a look maybe you could try just sending the controller and I'd use my battery for testing since everything else checked out. At least that way you get to keep the working brains and mileage if I get it working again.

@HanahsDax -- Yes, indeed, I could use a motor assembly and sensor footpad if those are parts you care to part with. The harness I only wanted to cut out all the little wires and use it as a direct EGO cable -- so if it is not damaged you are better off getting it to someone else who needs the whole thing. Email firstname.lastname@example.org Paypal ready. Again though, sorry your board malfunctioned.
Hmmm... On the other hand you could take my spare Plus controller and battery pack and turn your XR into a Plus if that is of any interest to you. (Edit: Actually my spare controller is 3206, not as desirable as 3208.)

@HanahsDax just curious, what hardware version is the record breaking board? 4207?
@stinkyface It was a 4206 ordered on 05/22/18 and was received 06/19/22. I remember checking the “Dude, where’s my board?” feature on the shipping info everyday. I ended up taking half a day off work the day it arrived and recorded my first ride which I titled Genesis and made up public on the ride section of the app. I used the board everyday expect for one which totaled to 1,038 days of use. Its ending mileage was at 6968 and I topped out at #49 for overall mileage the day it died.
@Lia Thanks for the offer, I may take you up on that. My original idea was to make a tribute with the rails and PCBA sort of like the one you did for your Vega. To be honest I wanted to give the board a makeover several miles back but couldn’t cuz I loved the pic you created of me and wanted to keep it resembling the artwork piece.
@blkwalnutgrwr I’ll post a pic of what I got. I actually have a plus controller I disassembled a while back and found a plus battery cell pack minus the casing, BMS and wiring harness so I could possibly create a plus with XR rails if the BMS in my original battery pack is able to accommodate a plus cell pack and is in decent working order. Thanks for the suggestion.
@HanahsDax A tribute would be cool, but I feel that board has so much more left to offer before it's retired. I bet we can get it working again :)
The brain of it clearly works as it connects to the app and processes everything. All that's stopping it is the controller not seeing the thumbs up from the BMS. Might take a while but I'll reverse engineer a schematic from mine if I have to in order to find the loss in communication.
Don't worry about changing the style, I'd be more than happy to do another once it's settled into it's new look. Will need some new vids for source material though so another reason to get you back on that XR ;)
@HanahsDax -- I concur with Lia, get your XR back in action!
If you are building a Plus, I have a BMS/battery-pack/case/&harness you can have. I took it out of my Plus this spring and have been using EGO batteries exclusively to power my Plus (and my V1, too).
@blkwalnutgrwr you got first dibs on whatever part you want/need/desire.
@HanahsDax -- Nice collection. All I need is a motor -- the well used one would work fine or the hub with no tire (although that one looks brand new) -- and a sensor footpad, which I like looking beat-up since they get that way quick anyway, and yours looks new, although I would take it. Let's talk prices in email. I am excited, I have been looking for a suitable motor for almost a year now.
Are you sure you want to disperse all those painstakingly collected Onewheel parts? My own collection of parts has not happened overnight, it has taken three years of watching, thinking, acting quickly, and gambling a little, too.

The patient has made it's way to me and I've spent this morning taking a look.
So far all checks out as we left off. Board powers on, everything measures normally but if you get it in a startup orientation error code 16 rears it's ugly head.
Did some probing and found resistor R49 was dead. This resistor runs between the green and white wires from the BMS which I assume to be RX and TX by the colours. These are pins 14 and 6 on the big 16 pin connector leading into the controller from the battery. I've highlighted the traces for you on a pic from my board.
The resistor connects both RX and TX just before entering U17 (I don't know why, maybe some pull-down solution). When measuring between the pins I get an open circuit so R49 has died open.
R49 is an 121ohm resistor according to the silk screen and I confirmed by probing my controller's pins 14 and 6. 121ohm resistors are.... uncommon so I made a 122ohm resistor from a 100ohm and 22ohm resistor in series.
Removed the dead one and wired in my resistor further back to give it more of a contact pad to solder to since these are larger and there are high voltage pins just next to it.
Alas, still error 16. This leads me to believe U17 is faulty which could have caused R49 to die. Unfortunately I can barely read the silk screen on it. I can make out the ST logo meaning it's a SGS Thomson chip.
I can just make out what appears to be 14 _ _ _ _ and below that either GX _ _ _ or 6K _ _ _. I'd take a pic but my phone refuses to get anything but a smudge.
I've toned back what appears to be Gnd and Vin for U17 so it looks like it should be getting power although I have yet to verify what is present on those pins when active.
Possible issues I've got it down to is
- Debris on the board is causing interference, gonna give it a clean later.
- My resistor replacement, albeit the right resistance may be inducing some other quirk that's ruining the signal.
- U17 isn't getting the right power input from elsewhere in the board.
- U17 is dead.
- A broken component/trace between U17 and the main ARM chip
- The ARM chip is faulty.
I don't think it's the last once since the rest of it works so unless something dumped voltage on some sensitive pins I can't see why that would be the case. My concern is if U17 is a programmed chip or I just cannot locate what it is. If so I'll need a donor board. I assume I might be able to pick up a "dead" one from somewhere if need be unless anyone has one lingering around they'd be happy to sell me for transplanting U17.
Edit: Looked back through my notes, the black pin being Gnd for the BMS's communication appears to come in on pin 5 but after a bit of tracing I actually cannot find where that pin comes back out.... maybe... just maybe.... that's the fault.
You've seen how many vias are on this board... gonna be a while >.>
