Bosch error 410: On-board computer buttons blocked

Bosch BES2 (Purion, Intuvia, Kiox, Nyon)Fix at homeSafe to keep riding

The display (Intuvia, Nyon, Purion or Kiox) thinks one or more of its own buttons is being held down permanently. The system usually keeps working, but you may not be able to change assist modes or navigate menus, and the code sits on screen until the button is released.

Likely causes

Dirt, grit or dried sweat under a button so it no longer springs back
Water inside the button membrane after heavy rain or pressure washing
The display is pressed against a bag, phone mount or cable that holds a button down
Worn or split rubber button after years of use
Damage to the button switch after a drop or crash

How to fix Bosch error 410

Press every button on the display a few times firmly; feel for one that does not click back
Take the display off its holder and clean around the buttons with a soft brush and a slightly damp cloth
If it has been wet, leave the display indoors overnight to dry, then refit it
Switch the system off and on again with the display refitted
Check nothing on the handlebar is pushing against a button while riding
If the code stays after cleaning and drying, the button switch itself is faulty: a dealer can confirm it and swap the display

Go to a dealer if: A dealer is needed when the code persists with clean, dry, freely moving buttons, because the switch inside the display has failed and the unit must be replaced.
Warranty: Dirty contacts, damaged cables and water ingress are treated as wear or user damage and are rarely covered; a genuine component fault within the 2-year warranty normally is.
Typical cost: Usually free if it is just dirt or water; a replacement Purion is roughly 100-150 EUR/USD, an Intuvia 150-250, a Kiox or Nyon 250-400 plus fitting.

Still stuck? Take a photo of the display and show it to a local e-bike workshop. Bring the bike's system name (e.g. Bosch Performance Line CX) and the exact code; that saves diagnostic time and money.
