Charger shows E29; display may indicate ‘Configuration Lock’; installer settings cannot be changed.

Safety first: No internal work is usually required for this issue.

• Enter installer PIN: If you have the installer code, enter it via the display or app to unlock configuration.
• Check backend portal: If the Polestar charger is managed by a fleet or energy provider, log into the management portal and verify that configuration changes are allowed.
• Factory reset: If permitted, perform a factory reset to clear the lock, then reconfigure the charger.
• Board replacement: If the lock state cannot be cleared and configuration remains inaccessible, the non‑volatile memory on the main control board may be faulty and require replacement.
