If you’re not sure whether it's compatible with your vehicle, send us your VIN or registration number and we’ll check for you.

2. What are the signs of a failing tailgate lock actuator?
Common symptoms include:

• Tailgate does not lock or unlock when you press the key-fob or button.

• Clicking, humming, or grinding noises from the latch area when trying to lock or unlock.

3. Is this an OEM part or aftermarket?
This is a high-quality replacement that matches OEM standards. Part 8K9827505A is used as a genuine Audi part, and many aftermarket versions reference the same number. 

4. How difficult is it to install this actuator?

• Unscrewing / unclipping the old actuator from the latch

• Fitting the new actuator and reassembling everything
  If you’re not confident working with vehicle door or tailgate internals, we recommend getting a professional to fit it.

5. Will replacing this actuator fix my boot not locking?
If the issue is due to a failed actuator, then yes — replacing this part often resolves locking-level problems. But:

• If the issue is wiring-related, or a sensor/control module fault, then simply replacing the actuator may not fix the problem.

• Make sure to verify other related components (latch, wiring) if the issue persists.

• Over time, a failing actuator could damage the latch or catch mechanism.
