My experience may be of interest, given it is quite bizarre!
My bike is Kalkoff 5B Move bought in October 2020.
I needed to tighten the steering head bearing but accidentally snapped off the end of my 1.5mm Allen key in the M3 grub screw that retains the two-part adjustable spacer directly beneath the steering stem. I thought I could simply drill it out with a left hand cobalt drill. Alas, as the grub screw turned out to be very hard stainless steel whist the collar in which it is threaded is soft aluminium the the process didn't go as planned and I ended up pretty much destroying the aluminium collar.
A replacement collar was obtained from my LBS. However, the cable from the Purion display to the motor is routed through the head tube and down the down tube to the motor. This cable only detaches at one end, the motor end! Hence the job became somewhat more involved than I had anticipated, requiring the removal of the motor from the frame to facilitate the pulling up of the said cable.
Anyway, the job went smoothly and, having completed it, I came to switch on the motor. The display showed error 510. Damn!
A search on the web resolved it as an 'internal sensor error' which didn't sound too good to me. I called my very helpful LBS who advised that they had only seen this once and it turned out to be a magnetised gear shift cable that had been reinstalled right alongside the motor. They advised me to remove the motor again and check the routing of the cables.
So, the next day I began stripping again. However, I had the good sense to switch the motor on after removing each part beginning with the cranks then the chainring. Imagine my surprise when the removal of the chainring removed the error! I placed a pocket navigation compass next to the chainring and the needle swung wildly showing it to be magnetised.
As the chain ring comprised of three components, I decided strip it down and reinstall each one back on the bike, one at time, and checking for the error between each one.
Would you believe it? After reinstalling the final component of the chainring there was no error.
I reassembled the bike and took it for a 12 mile test ride. No error!
The only explanation I can offer is that two or three of the components of the chainring were magnetised in the same direction and that when I reassembled them, I didn't align them in their original positions meaning that their magnetic poles were opposing and thereby cancelling each other out.
Hopefully this post may help someone else who gets the 510 error.
