Rail (625Wh) Bosch Gen 4 error code 511

[jono878]

I had a error code 511 today at the end of a run but the strange thing was my mate has just bought a focus ebike & also has a Bosch motor & had the same error code at the end of the run also?? So what would could cause this? Can these bikes some how interfere with each other ?

Both our bikes were fine, turn my on and off nothing came up again.

strong magnetic field??

As Mike says, or just some anomaly about that trail which triggered the motors to think there was a possible fault ?
