Mercedes-Benz E-Class W213 Power Trunk Retrofit Review

Enhancing Your Mercedes-Benz E-Class W213 with a Power Trunk Retrofit

The Mercedes-Benz E-Class W213 is renowned for its luxury and performance, but for many owners, the lack of a factory-installed power trunk function can be a notable inconvenience. Manually lifting and lowering the trunk, especially when your hands are full, is a common pain point. While newer vehicles often include this feature as standard, the W213 generation sometimes misses out, leaving owners to seek aftermarket solutions. Adding a power trunk not only resolves this practical issue but also elevates the vehicle's premium feel, offering a smooth, effortless operation that complements its sophisticated design.

The Need for a Power Trunk on the E-Class W213

The primary driver for considering a power trunk retrofit on a Mercedes-Benz E-Class W213 is the desire for increased convenience. Without this feature, owners must rely on manual force to open and close the trunk. A significant drawback is the absence of a dedicated button on the trunk lid itself for closing, forcing users to reach inside or use the key fob. This can be particularly cumbersome when carrying groceries, luggage, or in inclement weather. A power trunk system addresses these shortcomings directly, transforming a manual task into a seamless, automated experience.

Power Trunk Installation Process and Results

For Mercedes-Benz E-Class W213 owners seeking to add this functionality, a professional retrofit is the recommended approach. The process typically involves integrating a specialized power trunk system, such as the K-Pic system used in the example from South Korea. Before installation, the vehicle's interior and trunk area are carefully protected with covers to prevent any scratches or damage. The existing trunk components are then meticulously removed.

Installation process:

1. Component Integration: The core of the retrofit involves installing electric spindle motors on both sides of the trunk lid. These motors provide the necessary power to lift and lower the trunk smoothly.
2. Wiring and Control Unit Setup: Additional wiring is run, and a control unit is integrated to manage the power trunk's operation. This allows for seamless communication between the motors, the vehicle's existing systems, and new control points.
3. New Control Points: A new button is typically installed on the trunk lid itself, allowing for easy closing. The system is also configured to work with the original smart key and the button located inside the driver's cabin.
4. Reassembly and Testing: Once all components are installed and connected, the removed trim pieces are carefully reassembled. The entire system is then thoroughly tested to ensure smooth, reliable operation via the smart key, the new trunk button, and the interior switch.

Visually, the exterior of the W213 remains largely unchanged after the installation, preserving its elegant aesthetic. The most significant transformation is the newfound convenience. The trunk now opens and closes effortlessly with the press of a button, significantly enhancing the user experience. This upgrade is particularly beneficial for those who frequently use their trunk or have mobility considerations.

Benefits and Considerations for a Power Trunk Retrofit

The primary benefit of a power trunk retrofit for the Mercedes-Benz E-Class W213 is the substantial increase in convenience. The ability to open and close the trunk remotely via the smart key, or with a simple press of the new button on the lid or the existing interior switch, makes loading and unloading cargo far less of a chore. This feature proves invaluable when juggling multiple items or when dealing with adverse weather conditions. While the specific cost can vary based on the vehicle's year, the chosen kit, and labor rates, the investment generally falls within a reasonable range for the enhanced functionality provided. In the Korean market, the estimated cost for such a retrofit can range from approximately ₩400,000 to ₩800,000 (roughly $300-$600 USD, subject to exchange rates), though precise pricing requires a consultation. Durability is generally high, as reputable kits use robust motors and components designed for frequent use. Maintenance typically involves ensuring the seals are clean and lubricated, similar to standard trunk maintenance.
