Fuel Tank Flap Locking Motor for Mercedes-Benz

OEM-spec fuel flap locking motor (actuator) designed to control the locking and unlocking of the fuel filler flap on various Mercedes-Benz models. This precision actuator works in conjunction with the vehicle’s central locking system, ensuring the flap is securely locked when the doors are locked and released when unlocked.

Manufactured to exact OE standards, it guarantees smooth operation, correct electrical performance, and reliable long-term function — ideal as a direct replacement for worn or failed factory units.

Key Features:

• OE-Quality Replacement: Direct-fit design identical to original Mercedes-Benz actuator units.

• Durable Construction: High-torque internal motor and reinforced housing for longevity under repeated use.

• Plug & Play Installation: Compatible with factory electrical connectors and mounting points — no rewiring or modification required.

• Central Locking Integration: Operates in sync with vehicle door locking system for fuel flap security.

• Compact & Sealed Design: Moisture- and dust-resistant casing to withstand harsh operating environments.

Function Overview:
When the vehicle is locked via the key fob or door button, this actuator extends a locking pin that secures the fuel filler flap. Unlocking the vehicle retracts the pin, allowing access to the fuel cap.

Common Symptoms of Failure:

• Fuel flap does not lock/unlock with doors.

• Clicking noise from the rear when locking.
