Key Benefits — Why Choose This Door Lock Mechanism

• Restores central locking and door security — Replacing a faulty lock restores remote/central-locking operation so rear passenger door locks and unlocks reliably with the rest of the car.

• Solves common door-lock failures (door won’t lock/unlock, stuck latch, intermittent locking) — A worn or damaged actuator mech is often the cause — replacing it fixes issues such as door not responding to remote, manual locking issues, or inability to properly latch the door.

• Direct-fit replacement with OEM part number 4G0839015 — Designed for VW Touareg (and several other VW/Audi models), ensuring correct fitment with no modification needed.

• Improves convenience and safety (automatic locking, alarm integration, child-lock compatibility) — Ensures locking mechanism works smoothly, which is important for child-safety locks, alarm systems or automatic door-locking features. 

• Prevents further wear and avoids repeated repairs — A fresh lock mechanism reduces risk of latch failure or door-ajar issues that can lead to water leaks, door-seal wear or interior damage from mis-closures.

• Cost-effective vs full door/trip to main dealer — Rather than replacing the full door or paying heavy labour at main dealer prices, replacing just the lock mechanism is a budget-friendly fix that restores full functionality.

❓ Frequently Asked Questions (FAQ)

Q: What exactly does this door lock mechanism do?
A: It’s the electric latch/actuator module inside the rear left passenger door. It controls locking/unlocking (via central locking or remote), ensures the door latches properly when closed, and lets the vehicle’s electronics know when the door is closed to enable alarm/locking systems.

Q: What are common signs that this part is failing?
A: Typical symptoms include: rear door doesn’t lock/unlock with central locking or remote; door won’t latch fully; door lock intermittently fails; door opens itself or shows as ajar on dashboard; or you hear unusual noises from inside the door when locking/unlocking.

Q: Is this part compatible with my car?
A: This mechanism (OE 4G0839015) fits the rear left passenger-side door on many VW Touareg (2010-2018 for 7P5/7P6 generations) and several Audi/VW-group models as listed in the compatibility chart. Always match the old part number before ordering.

Q: Can I just replace the actuator — do I need to replace the whole door mechanism?
A: In most cases, yes — replacing the actuator mechanism restores locking/latching functionality without needing a full door or door-inner assembly replacement.

Q: Will replacing the lock mechanism solve all door-locking problems?
A: It will solve problems caused by a faulty latch/actuator. However, if issues stem from wiring, central locking module faults, child-lock lever issues or physical door-damage, further inspection may be needed.

Q: Why choose this part from D2P Autoparts rather than a second-hand or unknown brand unit?
A: Because this is a new, OEM-spec replacement — offering reliability, correct fitment, proper sealing, and long-life performance. Cheaper or used alternatives may have wear or unknown history — risking repeated failure.
