Review MERCEDES benz Trunk Tailgate Lock Latch Actuator Oem fits W164 ML350 ML63 GL350

The **Mercedes-Benz A1647400635 Trunk Tailgate Lock Latch Actuator** is a precision-engineered component designed exclusively for the **W164 (ML-Class) models**, including the **ML350, ML63, and GL350** (as well as their AMG variants), ensuring seamless integration with the vehicle s advanced locking and security systems. This high-performance actuator is a critical part of the tailgate mechanism, responsible for smoothly engaging and disengaging the latch with minimal effort, even under varying environmental conditions. Crafted from durable, corrosion-resistant materials, it is built to withstand the rigorous demands of daily use while maintaining the iconic Mercedes-Benz standard of reliability and refinement.

The actuator operates through an electric motor-driven mechanism, providing precise control over the tailgate s locking and unlocking functions, whether activated manually via the key fob, remote control, or the vehicle s keyless entry system. Its robust construction ensures smooth, silent operation, eliminating the risk of jamming or misalignment that can occur with lower-quality aftermarket replacements. The design incorporates a robust spring-loaded mechanism to maintain consistent tension, preventing premature wear and ensuring long-term durability even in extreme temperatures or after prolonged exposure to moisture.

For enthusiasts and owners seeking to restore or upgrade their Mercedes-Benz s tailgate functionality, this **OEM-spec actuator** is an essential replacement part, guaranteeing compatibility with the original wiring harness and control modules. Whether addressing a faulty latch, replacing a worn-out component, or performing a full tailgate restoration, this actuator delivers the same level of engineering excellence found in factory-equipped vehicles. Its seamless fitment and reliable performance make it an indispensable solution for maintaining the luxury, security, and convenience that Mercedes-Benz drivers expect from every component.

### **Pros and Cons of buying a Mercedes-Benz A1647400635 Trunk Tailgate Lock Latch Actuator (W164, X164, ML350, ML63, GL350)**

#### **Pros**

1. **Direct Compatibility** This part is specifically designed for the **W164 (ML350, ML63, GL350) and X164 (GLE 350, GLE 63)** models, ensuring a proper fit without modification. Avoiding mismatched parts reduces installation complications.

2. **OEM Quality** As an original equipment manufacturer (OEM) or high-quality aftermarket replacement, it maintains the same durability and performance standards as the factory part. This reduces the risk of premature failure compared to low-quality knockoffs.

3. **Reliability** The latch actuator is a critical component for trunk and tailgate operation. A reliable unit prevents unexpected malfunctions, such as the trunk failing to close or the tailgate sticking, which can be inconvenient or dangerous.

4. **Ease of Installation** Many aftermarket OEM-level parts come with clear instructions and are designed for straightforward replacement. If you have basic mechanical skills, you can often install it yourself, saving labor costs.

5. **Prevents Further Damage** A failing latch actuator can strain other components (e.g., wiring, sensors, or the trunk mechanism). Replacing it early prevents secondary issues that could lead to more expensive repairs.

6. **Warranty Coverage** Reputable sellers offer warranties (e.g., 6 months to 2 years), providing peace of mind in case of defects. This is especially useful if the part fails shortly after installation.

7. **Improved Functionality** If your current actuator is worn or malfunctioning, replacing it restores smooth operation, ensuring the trunk and tailgate open and close as intended, which is crucial for safety and convenience.

#### **Cons**

1. **Cost** OEM or high-quality aftermarket parts can be expensive, especially if purchased directly from Mercedes-Benz or authorized dealers. Prices may range from **$150 to $300 **, depending on the seller and model year.

2. **Potential Counterfeit Risks** Buying from untrusted sellers (e.g., unverified eBay, Amazon, or unknown marketplaces) increases the risk of receiving a **fake or low-quality part**. Always verify the seller s reputation and part authenticity.

3. **Installation Complexity** While many actuators are straightforward to replace, some models (especially those with integrated sensors or wiring) may require **disconnecting electrical connectors, removing trim panels, or adjusting sensors**. If you re not comfortable with DIY repairs, professional installation may be necessary, adding labor costs (**$100 $250**).

4. **Compatibility Variations** Some aftermarket parts may not account for **specific model-year differences** (e.g., wiring harnesses, sensor types, or mechanical linkages). Double-check that the part is **explicitly listed for your exact model and year** to avoid issues.

5. **Additional Repairs May Be Needed** If the failure was due to **corrosion, wiring issues, or sensor malfunctions**, replacing just the actuator may not fully resolve the problem. You might need to inspect or replace related components (e.g., wiring loom, sensors, or the trunk motor).

6. **Limited Availability** OEM parts may be **hard to find** if purchased from non-Mercedes sources, leading to longer wait times or higher prices. Aftermarket options are more widely available but vary in quality.

7. **Potential for Recalls or Defects** Even OEM parts can have **manufacturing defects** or be part of a **recall batch**. Always check for **recalls** (via Mercedes-Benz or NHTSA) before purchasing, especially if buying used or from a secondary market.
