Fuel flap locking motor (actuator) Designed to control the locking and unlocking of the fuel filler flap on various Mercedes-Benz models. This 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.
Key Features:
Replacement: Replacement actuator for the listed vehicles; compare the connector and part number with your existing part before ordering.
Construction: High-torque internal motor and reinforced housing under repeated use.
Central Locking Integration: Operates in sync with vehicle door locking system for fuel flap security.
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.

Q&A
Q1: How do I know my actuator has failed?
A1: If your fuel flap no longer locks/unlocks or you hear a faint clicking without movement, the actuator is likely faulty.
Q2: Is this a universal Mercedes part?
A2: The same design is used across many Mercedes models, but the mounting orientation may vary. Always verify fitment via VIN.
Q3: Can I replace it myself?
A3: Yes—requires basic tools and access to the flap area; typically a 15–30 minute DIY job.
Q4: Does it need coding or programming?
A4: Coding requirements depend on the vehicle and actuator variant; confirm with your installer before ordering.
Condition: New aftermarket replacement part. Not an original Mercedes-Benz part; brand and model names are used only to show fitment.
