No error X3 help motor
Hey everyone,
I’m having a strange issue with my VanMoof X3 and I honestly can’t figure out where the problem is because I’m not getting any consistent error code anymore.
The motor sometimes works and sometimes doesn’t. Occasionally it gives assistance, but it feels weak and I don’t think the bike is reaching the normal 25 km/h anymore. Other times the motor barely responds at all.
I also sometimes hear a faint buzzing/hissing sound coming from inside the frame. I already checked some connectors and measured a few things, but I’m still not sure if this is:
- the wiring harness
- motor cable
- hall sensors
- controller/MOSFET issue
- or something else
No clear Error 44 at the moment, which makes diagnosing harder.
I added a video of the current situation. Any help, ideas, or things I should test would really be appreciated!
