Review MERCEDES Oem 12v 902 85c Sunroof Motor 005 fits S500 W220 500 390 200 2004

The **500 12V 902 85C 2004 Mercedes-Benz W220 Sunroof Motor (Part Numbers 390 200 005)** is a precision-engineered, high-performance electric actuator designed exclusively for the luxury and iconic **Mercedes-Benz S-Class (W220) models**, including the S500 and its variants produced between 2000 and 2005. This sunroof motor is a critical component of the vehicle s sophisticated **electro-hydraulic or electric sunroof system**, ensuring smooth, reliable, and silent operation while maintaining the S-Class s signature blend of opulence and engineering excellence. Crafted from high-grade materials, the motor features a **robust 12-volt DC electric drive system** with a **902-series designation**, indicating its compatibility with Mercedes-Benz s proprietary wiring and control modules. The **85C** designation further specifies its unique mechanical and electrical specifications, tailored to the W220 s sunroof mechanism, which often incorporates a **hydraulic assist** for effortless opening and closing, even when the vehicle is stationary or in motion.

This sunroof motor is built to withstand the demands of daily use in premium vehicles, offering **seamless integration** with the S-Class s advanced driver-assistance systems, climate control, and infotainment interfaces. The **390 200 005** part number is a direct reference to Mercedes-Benz s **OEM (Original Equipment Manufacturer) catalog**, ensuring an exact match in terms of torque, speed, and operational range. The motor s design prioritizes **durability and longevity**, with reinforced brushless or brushed DC components (depending on the specific variant) that minimize wear and reduce the risk of electrical failure. Its **low-noise operation** is a hallmark of Mercedes-Benz engineering, ensuring that the sunroof s movement remains virtually inaudible, even at high speeds or in quiet cabin conditions. The motor s **precise gearing system** is engineered to handle the sunroof s **hydraulic or mechanical linkage** with minimal backlash, providing a buttery-smooth motion that aligns with the S-Class s reputation for refined luxury.

For restoration or replacement purposes, this sunroof motor is an **essential OEM-grade component** that restores the original functionality of the W220 s sunroof system without compromising performance or aesthetics. It is fully compatible with the **2004 S500 s** (and other W220 models ) **electronic control units (ECUs)**, including the sunroof actuator relay and the body control module (BCM), ensuring proper communication and operation. Whether installed in a **showroom-worthy restoration** or as part of a **routine maintenance upgrade**, this motor guarantees that the sunroof operates with the same **effortless precision** as it did when the vehicle was new. Its **universal fitment** within the W220 series including the S350, S430, and S600 makes it a versatile choice for enthusiasts and professionals alike, bridging the gap between original equipment and aftermarket solutions. With its **high-quality construction, OEM specifications, and Mercedes-Benz engineering standards**, this sunroof motor is not merely a replacement part but a **crucial element in maintaining the S-Class s legendary driving experience and interior ambiance**.

### **Pros and Cons of Buying a 2004 Mercedes-Benz S500 (W220) Sunroof Motor (Part No. 390 200 005)**

#### **Pros:**

1. **High Quality and Reliability** Mercedes-Benz components, including sunroof motors, are known for durability and precision engineering. The W220 series (1999 2005) was well-built, and the sunroof mechanism was designed to last with proper maintenance.

2. **Direct Fitment** The part number **390 200 005** is the original equipment (OEM) sunroof motor for the 2004 S500 (W220). This ensures a perfect match in terms of compatibility, reducing the risk of installation issues.

3. **Aftermarket Availability** While OEM parts are ideal, this motor is also available from reputable aftermarket suppliers (e.g., ACDelco, Bosch, or specialized Mercedes parts vendors), which may offer cost savings without sacrificing quality.

4. **Easy Installation** The W220 sunroof system is relatively straightforward to replace, especially for those with basic mechanical skills. Many owners and mechanics report that the job takes **2 4 hours** with the right tools.

5. **Long-Term Durability** If the motor fails, replacing it with an OEM or high-quality aftermarket unit can restore functionality for **another 10 15 years**, depending on usage and maintenance.

6. **Value for Money** Compared to newer luxury vehicles, the cost of this part is relatively low (typically **$200 $500** depending on source), making it a cost-effective repair rather than a full sunroof replacement.

7. **Prevents Water Leaks & Further Damage** A failing sunroof motor can lead to water leaks, electrical issues, or even roof panel damage if ignored. Replacing it early prevents secondary problems.

---

#### **Cons:**

1. **Age and Wear** The W220 is now **20 years old**, meaning the sunroof mechanism may have accumulated wear in the tracks, seals, or hinges. Simply replacing the motor won t fix all issues additional maintenance (e.g., lubrication, seal replacement) may be needed.

2. **Potential for Additional Repairs** If the sunroof has been neglected, the **tracks, seals, or electrical wiring** may be damaged. A full sunroof service (not just the motor) could be required, increasing costs.

3. **Aftermarket Quality Variability** While some aftermarket motors are excellent, others may be cheaper but lower in quality, leading to premature failure. Always opt for **OEM or high-end aftermarket** (e.g., Bosch, Dorman) to avoid this.

4. **Electrical Issues** The sunroof motor is controlled by the **body control module (BCM)**. If the BCM is faulty or the wiring is damaged, the new motor may not function properly. A diagnostic check is recommended before purchase.

5. **Labor Costs** While the part itself is affordable, **labor costs** (if not DIY) can add up, especially in areas with high mechanic rates. Expect **$150 $300** in labor depending on the shop.

6. **Rust and Corrosion Risk** Older Mercedes, especially in snowy or humid climates, may have **rusted sunroof frames or tracks**. This can make installation difficult and may require additional repairs.

7. **Limited Availability of OEM Parts** While this specific motor is still available, some OEM components for the W220 are becoming harder to source. Buying early ensures you get the genuine part.
