What to try

Step 1 — Make sure the latest firmware is installed. Pair your bike with the original VanMoof app (see callout below) and let it apply any pending firmware updates.
Step 2 — Reset your bike. Hold the power button until the bike fully powers down, wait a few seconds, and turn it back on. A 10-second power-button hold is Step 2 of VanMoof's official troubleshooting sequence and often clears transient codes.
Step 3 — Perform a system restart. If the code persists after a reset, do a full system restart from the bike menu.
