Review MERCEDES benz 96 Light Control Module fits 560SEC 300E E320 1988
The **Mercedes-Benz 591.088 MB1W88 1988 96 300E/E320 Light Control Module (Part Number: 238106, Original OEM Code: 1265420132)** is a precision-engineered electronic component integral to the illumination and signaling systems of the iconic W124 generation Mercedes-Benz E-Class, specifically the 300E and E320 models produced between 1988 and 1993. This module serves as the central hub for managing a wide array of lighting functions, including headlights, tail lights, turn signals, brake lights, reverse lights, and even the ambient interior lighting in some configurations. Designed to interface seamlessly with the vehicle s early 1990s-era electronic architecture, this module operates as a relay and control unit, translating driver inputs and sensor data into precise electrical signals that activate or deactivate the appropriate lamps with reliability and efficiency. Crafted to Mercedes-Benz s exacting standards, the module is housed in a robust, corrosion-resistant casing, often featuring a mix of metal and high-grade plastic components, ensuring durability in both urban and highway driving conditions. Its internal circuitry includes a series of relays, diodes, and integrated circuits that coordinate the timing and sequencing of lights, such as the gradual fade-in of headlights or the synchronized activation of turn signals, enhancing both safety and the vehicle s signature luxury aesthetic. For restoration or maintenance purposes, this module is a critical replacement part, as it directly impacts the vehicle s compliance with modern lighting regulations and ensures that all signals are clearly visible to other drivers. Whether used in a meticulously restored classic or as an original part in a well-preserved example, the 1265420132 light control module exemplifies Mercedes-Benz s commitment to engineering excellence, blending functionality with the timeless elegance of the W124 platform.

- The **5-speed automatic transmission (5G-Tronic)** is smooth and reliable, though some early models may require attention.
- The **chassis and suspension** are well-built, though later models (post-1991) improved upon early issues.
3. **Classic Mercedes-Benz Prestige**
- The W124 is a highly regarded classic, appreciating in value over time, especially well-maintained examples.
- Owning a **1988 model** places you in a transitional era between the older W123 and the more modern W210/W211 generations.
- Enthusiasts value the **aesthetic appeal** of the W124, with clean lines and a timeless design.
4. **Parts Availability (Compared to Older Models)**
- While not as abundant as modern Mercedes parts, the **W124 has a strong aftermarket and OEM support** due to its popularity.
- The **Light Control Module (LCM) is a common component**, and replacements (including the **R238106**) are relatively easy to source from Mercedes dealerships or specialty suppliers.
- Many **electrical and mechanical components** are shared with other W124 models, reducing repair costs.
5. **Potential for Restoration or Modification**
- The W124 is a **popular project car** for restoration, allowing owners to customize interiors, exteriors, or performance.
- **Engine swaps** (e.g., M117 to a more powerful inline-six or V8) are feasible with proper modifications.
- **Lighting upgrades** (including modern LED or HID conversions) are possible, though compatibility with the LCM must be verified.
6. **Fuel Efficiency and Driving Dynamics**
- The **3.2L V6** offers a good balance of power ( 170 hp) and efficiency ( 12 14 MPG city, 16 18 MPG highway).
- The **smooth automatic transmission** provides a comfortable driving experience.
- The **steering and handling** are precise for a luxury sedan, though later models improved upon early weight distribution issues.
7. **Resale Value (For Well-Maintained Examples)**
- A **restored or low-mileage 1988 W124 300E** can hold its value well, especially if documented with service records.
- The **LCM and other electrical components** being in good condition (e.g., no blown fuses, working sensors) positively impacts resale.

### **Cons of Buying This Vehicle**
1. **Electrical and Lighting System Reliability**
- The **Light Control Module (LCM) can be finicky**, especially in older models. The **R238106** may have issues with:- **Faulty wiring harnesses** (common in early W124s due to poor grounding or corrosion).
- **Sensor failures** (e.g., headlight leveling sensors, turn signal flasher issues).
- **Compatibility with aftermarket lighting** (some modern bulbs or LED conversions may not work correctly).
- **Blown fuses or relay failures** are frequent in older Mercedes electrical systems.
- **Headlight dimming issues** (common in early W124s) may require recalibration or module replacement.
2. **Maintenance and Repair Costs**
- **Regular upkeep is essential** neglect can lead to expensive failures (e.g., timing belt, water pump, suspension bushings).
- **Labor costs** at Mercedes dealerships are high, though independent specialists can reduce expenses.
- **Common wear items** include:- **Suspension components** (shock absorbers, bushings, control arms).
- **Brakes** (drum brakes on early models, disc brakes on later ones).
- **Fuel system** (carburetor or early fuel injection issues in some engines).
- **Exhaust system** (rust and leaks are common).
3. **Engine and Transmission Considerations**
- The **M117 3.2L V6** is generally reliable but can develop **carbon buildup** (common in older Mercedes engines), requiring decarbonization.
- **Early automatic transmissions (pre-1990)** may have **slippage or rough shifting**, requiring fluid changes and potential rebuilds.
- **Coolant leaks** (from the thermostat housing or water pump) are a known issue that must be addressed promptly.
4. **Interior Wear and Tear**

- **Electrical failures** (e.g., dead dashboard lights, malfunctioning power seats) are common and can be costly to repair.
- **Rust** (especially in the wheel wells, sills, and undercarriage) is a concern in older German cars exposed to salt or poor storage.
5. **Driving Experience Limitations**
- The **W124 is not as nimble as modern sports sedans** handling is adequate but not sporty.
- **Early models (pre-1990) have softer suspension settings**, which can feel less engaging than later models.
- **Noise levels** (wind, road, and engine) are higher than in newer Mercedes models.
6. **Fuel and Emissions Compliance**
- The **1988 model year** predates modern emissions standards, meaning:- **Smog checks** may be required in some regions.
- **Modern fuel additives** (e.g., ethanol blends) can affect performance and fuel system longevity.
- **Exhaust system modifications** (e.g., catalytic converter removal) are illegal in many areas and void warranties.
7. **Finding a Reliable Example**
- **Scams and misrepresented condition** are common in the classic car market. Always:- Verify the **service history** (especially for the LCM and electrical system).
- Check for **rust, frame damage, or accident history** (use a pre-purchase inspection).
- Test the **lighting system thoroughly** (headlights, turn signals, brake lights, hazard flasher).
- **Hidden issues** (e.g., water leaks, electrical shorts) can turn a "project car" into a money pit.

### **Key Considerations Before Purchase**
1. **Inspect the Light Control Module (LCM) Thoroughly**
- Test all **headlights (high/low beam), turn signals, brake lights, and hazard flasher**.
- Check for **flickering, delayed response, or complete failure** these indicate a faulty LCM or wiring issue.
- If the **R238106 module is replaced**, confirm it s a **genuine Mercedes part** (counterfeit modules can cause further problems).
2. **Review Full Service Records**
- Look for **regular oil changes, timing belt replacements, and electrical system checks**.
- **Electrical work** (e.g., wiring repairs, fuse replacements) should be documented.
3. **Check for Rust and Structural Damage**
- Inspect the **wheel wells, sills, and undercarriage** for rust holes.
- Ensure the **frame and subframe** are intact (rust can compromise structural integrity).
4. **Test Drive and Listen for Issues**
- **Engine noise** (knocking, ticking, or whining) may indicate bearing or valve issues.
- **Transmission smoothness** jerking or delayed shifts suggest problems.
- **Braking performance** squeaking, grinding, or soft pedal can mean worn components.
