The **Volvo 31352205 Sunroof Control Module** is a precision-engineered component designed exclusively for the **2012 Volvo 70 Series (70B body)**, serving as the critical interface between the vehicle s Body Control Module (BCM) and the rear sunroof mechanism. This high-performance module is responsible for managing the sunroof s electrical functions, including opening, closing, tilting, and emergency unlocking, ensuring seamless operation while maintaining the integrity of Volvo s renowned safety and reliability standards.

The module incorporates advanced diagnostics capabilities, enabling the vehicle s onboard computer to detect and troubleshoot potential malfunctions, such as motor failures, sensor errors, or wiring issues, thereby enhancing the overall reliability of the sunroof system. Whether used in a restoration project, replacement scenario, or as a preventive maintenance upgrade, this module guarantees smooth, responsive sunroof functionality, preserving the aesthetic and practical value of the Volvo 70 Series. Its direct integration with the **BCM (Body Control Module)** ensures synchronized operation with other vehicle systems, such as door locks, alarm triggers, and power accessories, maintaining the cohesive performance expected from a Volvo. For owners and technicians seeking a genuine, high-quality replacement that adheres to Volvo s exacting engineering standards, this sunroof control module represents the ideal solution for restoring or maintaining optimal functionality in the rear sunroof system.
Buying a replacement **Volvo 31352205 Sunroof Control Module (2012 70 Series Body, BCM Rear Roof)** can be a practical solution for restoring functionality to a sunroof system, but it comes with several considerations. Below is a detailed breakdown of the pros and cons, followed by a conclusion and recommendation.
---
### **Pros of Buying a Replacement Sunroof Control Module**
1. **Restores Full Sunroof Functionality**
The sunroof control module manages the motor, switches, and safety mechanisms (e.g., rain sensors, tilt/ventilation controls). A faulty module can cause the sunroof to fail entirely or operate erratically (e.g., not opening/closing, stalling mid-motion). Replacing it often resolves these issues, restoring the sunroof to proper operation.
2. **Cost-Effective Alternative to Full Sunroof Replacement**
Sunroof systems are complex, and replacing the entire unit (motor, glass, seals, etc.) can cost **$1,500 $3,000 ** depending on the vehicle. The control module itself is significantly cheaper (typically **$100 $300** for a used/refurbished unit or **$200 $500** for new/OEM). This makes it a budget-friendly fix for electrical or software-related failures.
3. **Prevents Further Damage**
A failing sunroof control module may cause the sunroof motor to overheat or the glass to jam, potentially damaging the tracks or seals. Addressing the issue early avoids more extensive (and costly) repairs down the line.
4. **Compatibility with Modern Diagnostics**
Many newer Volvo models (including the 2012 70 Series) use **CAN bus communication** between the BCM (Body Control Module) and the sunroof system. A compatible replacement module ensures proper integration with the vehicle s electrical network, allowing for diagnostics via tools like **IKEA, VIDA, or even basic OBD-II scanners** (though advanced troubleshooting may still be needed).
5. **Potential for DIY Installation**
While some Volvo sunroof repairs require specialized tools or experience, replacing the control module is often a **pluggable or bolted-in component** (depending on the model year and trim). This can be done by an experienced DIYer with basic automotive knowledge, saving labor costs.
6. **Warranty or Guarantee Coverage**
Purchasing from a reputable seller (e.g., **Volvo Specialists, eBay verified sellers, or authorized dealers**) may include a **limited warranty** (e.g., 30 90 days). This provides peace of mind in case the module fails shortly after installation.
7. **Avoids Dealer Price Gouging**
Volvo dealerships often charge **$500 $1,200 ** for labor and parts when replacing a sunroof control module. Buying aftermarket or used parts can significantly reduce costs while still achieving the same result.
---
### **Cons of Buying a Replacement Sunroof Control Module**
1. **Potential for Counterfeit or Low-Quality Parts**
The aftermarket for Volvo parts is flooded with **counterfeit or poorly manufactured modules**, especially on platforms like eBay or Amazon. These may:
- Fail prematurely (within weeks or months).
- Not communicate properly with the BCM, causing intermittent issues.
- Lack proper calibration, leading to error codes (e.g., **P1554, P1555, or P1556** for sunroof-related faults).
**Solution:** Stick to **OEM, Volvo-approved aftermarket brands (e.g., ACDelco, Bosch, or Mann Filter), or reputable used parts sellers** with return policies.
2. **Requires Proper Recalibration**
Unlike simpler modules (e.g., a door lock actuator), sunroof control modules often need **reprogramming or recalibration** after replacement. This may involve:
- **BCM reprogramming** (using tools like VIDA or IKEA).
- **Sunroof motor relearn** (some systems require a "learn cycle" where the motor is moved manually to establish proper limits).
- **Error code clearing** (after installation, the system may throw codes that need to be addressed).
**Solution:** Have a **Volvo technician or someone with VIDA experience** perform the recalibration to avoid persistent issues.
3. **Underlying Electrical or Mechanical Issues May Persist**
If the sunroof control module fails due to **wiring damage, a faulty motor, or a failing rain sensor**, replacing just the module may provide temporary relief but not a permanent fix. Common related problems include:
- **Corroded or damaged wiring harnesses** (common in older Volvos due to exposure to moisture).
- **Worn sunroof motor brushes** (in older models, the motor may fail shortly after the module is replaced).
- **Faulty rain sensors or tilt switches** (these can cause the sunroof to malfunction even with a new module).
**Solution:** Inspect the **entire sunroof system** (wiring, motor, sensors) before and after replacement to identify root causes.
4. **Limited Availability of OEM Parts**
While aftermarket modules exist, ** genuine Volvo OEM parts** may be harder to find for older models (pre-2015). OEM parts are more reliable but often more expensive. Aftermarket alternatives may not match the durability of OEM components.
5. **Potential for Voiding Warranty (If Applicable)**
If the vehicle is still under **factory warranty**, installing aftermarket parts may void coverage for sunroof-related issues. Volvo s warranty typically covers **defective components**, but aftermarket replacements could be considered a "modification."
**Solution:** Check the warranty terms or consult a dealer before proceeding if the vehicle is still under warranty.
6. **Installation Complexity for Non-Experienced DIYers**
While the module itself is often straightforward to replace, **recalibration and troubleshooting** can be complex. Mistakes during installation (e.g., improper wiring, not clearing error codes) can lead to:
- The sunroof **not responding at all**.
- **Intermittent operation** (e.g., working sometimes but not others).
- **New error codes** appearing after installation.
**Solution:** If unsure, have a **Volvo specialist or electrician** perform the installation and recalibration.
7. **Risk of Compatibility Issues with Modified or Aftermarket Upgrades**
If the vehicle has had **aftermarket modifications** (e.g., custom wiring, non-OEM BCM, or sunroof motor upgrades), the new control module may not integrate properly. This is less common in stock 2012 70 Series models but worth considering if the car has been altered.

### **Conclusion**
Buying a replacement **Volvo 31352205 Sunroof Control Module** for a 2012 70 Series is a **cost-effective and practical solution** for restoring sunroof functionality when the issue stems from a faulty module. It avoids the expense of a full sunroof rebuild while addressing electrical or software-related failures. However, the success of the repair depends on:
- **Sourcing a high-quality module** (preferably OEM or Volvo-approved aftermarket).
- **Proper recalibration and diagnostics** to ensure compatibility with the BCM.
- **Addressing any underlying mechanical or wiring issues** that may contribute to failure.
If the sunroof has **wiring damage, a failing motor, or sensor issues**, replacing just the module may not provide a long-term fix. In such cases, a **full sunroof service** (including motor and glass inspection) may be necessary.
---
### **Recommendation**
1. **Verify the Exact Issue**
Before purchasing, confirm that the sunroof control module is indeed the problem. Use an **OBD-II scanner** (or VIDA) to check for **sunroof-related error codes** (e.g., P1554, P1555). If the motor turns but the glass doesn t move, or if the system is unresponsive, the module is likely faulty.
2. **Choose the Right Module**
- **OEM (Best):** Order directly from **Volvo Parts** or an authorized dealer for guaranteed compatibility.
- **Aftermarket (Budget-Friendly):** Opt for **reputable brands** like **Bosch, ACDelco, or Mann Filter**, and check reviews for reliability.
- **Used/Refurbished (Cheapest):** Purchase from **trusted sellers** (e.g., eBay with positive feedback) and test the module before installation if possible.
3. **Prepare for Recalibration**
Have access to **VIDA software** (or hire a technician with it) to reprogram the BCM and perform any necessary sunroof motor relearn procedures. If you re not comfortable with this, take the car to a **Volvo specialist**.
4. **Inspect the Entire System**
While replacing the module, check for:- **Corrosion or damage in wiring harnesses** (especially near the sunroof mechanism).
- **Worn motor brushes** (common in older Volvos; may need replacement).
- **Faulty rain sensors or tilt switches** (these can cause the
