❓ FAQs — Rear Door Lock Actuator / Mechanism

1. Which Audi models is this part compatible with?
This pair of actuators fits:

• Audi A3 (8P): common on 2003–2012 models.

• Audi A6 (C6): both saloon and estate versions.

• Audi A8 (4E): includes relevant model years for the 4E chassis.

2. What are the OEM / reference part numbers?
Typical OEM and reference numbers for these actuators include 4F0839015 / 8E0839015AA.

3. What does a door lock actuator / mechanism do?
It is the component inside the door that physically locks and unlocks the door using your central locking system. When you press the lock or unlock button, the actuator drives a mechanism to catch or release the latch.

4. What are the common signs of a failing actuator?

• The door doesn’t lock or unlock using the remote or interior switch.

• Clicking or buzzing noise from inside the door when locking/unlocking.

• Intermittent operation: sometimes lock works, sometimes not.

• Manual lock (using the key or inside handle) works, but remote doesn’t.

5. Is installation difficult?

• You need to remove the rear door trim / panel.

• Disconnect the electrical connector for the actuator.

• Unbolt the actuator / latch mechanism.

• Refit the new mechanism, reconnect wiring, test locks before reassembling the door panel.

6. Will replacing this fix all central locking issues?
If the problem is a faulty actuator, then yes — replacing it typically restores proper central locking. But if the issue is wiring, a failing central locking module, or a broken latch, further diagnosis may be needed.

7. Do I need to reprogram or code anything?
Generally, no. These actuators are plug‑and‑play, and you shouldn’t need to code them after fitting — just test the locks and ensure everything works.

8. Does D2P AutoParts provide a warranty?
Yes — we back our locking mechanisms with a 12‑month parts warranty, giving you peace of mind in case of any early failures.

9. Is this part OEM or aftermarket?
This is a high-quality aftermarket / OEM-equivalent actuator, designed to match the fit, function, and connectors of the original Audi part at a lower cost.
