Hi everyone,

Sorry for reporting back this late. I got my bike back on June 5th, roughly 3 weeks after I brought it in. In hindsight, I don't think there's any reason to blame my dealer, maybe I was even lucky this error appeared while the bike was at the shop.
My dealer showed me a video of the erroneous behavior; he turns on the bike, it starts up, and after a few seconds shuts down again. When I checked the logs later, all I saw was many occurrences of:

>> Turning OFF DCDC. Flags: 0x01   
>> Entering Critical Error Shutdown

It took them a long time to find the source of this behavior, and apparently they finally found a faulty connector to the battery with a bent or otherwise deformed pin. I have to assume this was a manufacturing flaw, even though I never had problems before. I also don't see how this could in any way be connected to the update he tried to install, which was rejected and afterwards the error showed up.

Be it as it may, they fixed the faulty connector, under warranty of course, and the error went away. Everything seems to be fine now, and maybe I was very lucky my bike never decided to just shut down while riding before.

So I took my 3 month old Zero DSR to the dealer to install a rain guard and replace a crushed bar end plug. Simple as that. On this occasion, I asked them to also do the routine maintenance, which is supposedly required according to the owner's manual. The guy told me he just needs to hook the bike up to the PC so Zero can see it's been checked on.
Almost on my way to pick up the bike two days later, I first called, just to learn that he tried to update my DSR's firmware, which failed and now the bike won't start anymore. He then got in contact with a guy from Zero for remote support.
This was two weeks ago and there doesn't seem to be any progress still. My DSR had been working flawlessly before, I even did a firmware update successfully once using the phone app, and there were no further updates available since then.

I'm asking advice on how to proceed with this case. My dealer is very nice, but I get the feeling they're not very knowledgeable with the Zeros. Despite that, they and Zero require all maintenance to be done by the dealer. I know this is a pain point for many Zero owners, I'm just wondering if anyone has experience this particular issue before. Would you recommend
- Insisting on a replacement if they can't get the bike to work soon
- Just wait it out (if there's no other option...)
- Any advice on how to 'reset' the firmware? I looked up https://zeromanual.com/wiki/BMS_Reset_Procedure, but I can't imagine they haven't at least tried this stuff?
- Another thread mentioned that the dealer had to update their PC software first. Could this still be an issue?

I will call my dealer soon for an update (no pun intended) and am just trying to figure out what my options are. Any advice is most welcome
Thanks and safe riding

Hello guys,

I newly registered because I finally got my 2021 Zero DSR. I have read a lot on this forum already, but this is my first time posting because I have a small problem.

I was cleaning my bike after today's ride, and the black "BMS cover plug" (behind the front wheel), which covers the LED indicators and reset buttons of the BMS, just fell off at the slightest touch. I am actually surprised it stayed on while riding. I can put the cover plug back in, and it sticks a little bit to the grease, but there is no "click" or anything which would keep it in place properly.

Is this normal? Has anyone lost their BMS cover plug or done anything to attach it more securely?

Thanks for your help. As long as there are no bigger issues I am very happy with my DSR
