Safety first: Do not force the connector lock with tools; you may damage the plug or housing.

Inspect for obstruction: Check the area around the Type 2 socket on the wallbox for dirt, stones, or ice. Gently remove any foreign objects. In cold climates, allow ice to melt naturally; do not pour boiling water on the connector.
Cycle lock via software (if available): Some Audi chargers allow manual lock/unlock via app or front panel. Attempt to lock and unlock several times to free a sticking mechanism.
Power reset: Turn off the breaker for 2 minutes, then restore power. Sometimes the lock actuator will re-home on startup and clear the error.
Check lock wiring: With power off and cover removed by a professional, inspect the small harness going to the lock actuator and position sensor. Ensure connectors are fully seated and wires are not pinched.
Replace lock assembly: If the actuator does not move or the sensor does not change state when commanded, replace the connector locking mechanism assembly with an Audi-approved part.

Do not bypass the locking system; it is a safety feature. Replace defective lock components to restore normal operation.

Audi EV charger shows E06 and refuses to start; vehicle may show ‘Locking error’ or ‘Charging station locked’.
