FAQs 

1. Which Mercedes models is this actuator compatible with?
This part (1647400635 / A1647400635) fits a number of Mercedes models, including:

  • M-Class W164 (2007–2009) SUVs

  • E-Class W211 (estate / saloon) for the tailgate / boot lock

2. What does the tailgate lock actuator do?
The actuator is part of the central locking system for the tailgate (boot). It powers the latch mechanism to lock and unlock the tailgate electronically, ensuring secure closure and integration with your car’s locking system.

3. What symptoms indicate the actuator is failing?
Look out for:

  • Tailgate not locking or unlocking properly

  • Clicking, humming, or grinding noises when you press the lock/unlock button

  • Central locking fails / intermittent tailgate locking

  • Warning light / error related to tailgate or lock

4. Is this a direct OEM replacement?
Yes — this is a genuine OEM-spec (or very close) boot lock actuator. The part number 1647400635 is used across several Mercedes OEM diagrams.

5. How do I replace the actuator? Is installation difficult?

  • You will need to remove the interior trim panel from the tailgate to access the actuator.

  • Unplug the 10-pin electrical connector and unbolt the old actuator / latch unit.

  • Fit the replacement part and reassemble everything carefully.
    If you’re not confident working with car internals, a professional install is recommended to avoid damaging trim or misaligning the latch.

6. Will replacing this actuator fix my tailgate locking issues?
In many cases, yes. If the problem is due to a failed or worn actuator, installing a new one should restore proper locking. However, if the fault lies elsewhere (e.g. wiring, central locking module), further diagnosis might be needed.

7. Is there a warranty on this part?
Warranty depends on the seller, but for good-quality parts like this, a 12-month warranty is common. (Check Warranty.)

8. Can I still drive the car if the tailgate lock actuator fails?
Technically yes, but it’s not ideal:

  • The tailgate may not lock securely, posing a security risk.

  • You may get warning lights related to the tailgate or lock.

  • Over time, a failed actuator could worsen or damage the latch mechanism.

9. Why choose this part from D2P AutoParts (or a trusted OEM parts supplier)?

  • OEM-spec quality ensures longer durability and reliable function.

  • Direct-fit replacement means no modification needed.

  • Helps restore full central locking function for the tailgate.

  • Great value compared to dealer prices.
