Review BMW Sedan Door Mirror Left Memory Heated Facelift Silver fits E46 TOURING 2003

The **BMW 42491-03-E46 Touring Door Mirror Left, Memory Heated (Facelift, Part Number 51167153087)** is a premium, high-performance exterior component designed exclusively for the iconic **E46 5-Series Touring (Touring Wagon)** models, specifically those equipped with the **facelift generation** (produced between 2000 and 2006). This left-side door mirror is engineered to deliver both functionality and style, seamlessly integrating with the vehicle s sleek, aerodynamic profile while enhancing driver convenience and safety. Crafted from durable, high-quality materials, the mirror features a **memory function**, allowing the driver to preset and recall their preferred mirror angle with a simple press of a button, eliminating the need for manual adjustments and reducing blind spots during parking or lane changes. The **heated element** ensures crystal-clear visibility even in freezing conditions, preventing ice or fog buildup that could obstruct the driver s rearward view, particularly in winter climates or during sudden temperature drops.

Beyond its practical benefits, this mirror embodies BMW s signature attention to detail, with a **smooth, contoured design** that complements the car s sporty yet refined aesthetic. The **black-painted housing** matches the vehicle s exterior trim, while the **silver-tone mirror head** adds a touch of elegance, reinforcing the E46 s distinctive character. The mirror is equipped with a **quick-release mechanism**, making installation straightforward for mechanics or DIY enthusiasts, though it is recommended to follow BMW s recommended torque specifications to ensure a secure fit. This part is a **direct-fit replacement**, meaning it is engineered to match the original dimensions and mounting points of the factory mirror, ensuring a perfect alignment with the door panel and minimizing gaps or misalignment. Whether restoring an older E46 to its original glory or upgrading a well-loved Touring Wagon, this **memory-heated left-side door mirror** is an essential component for maintaining both performance and comfort, embodying the perfect blend of German engineering precision and driver-centric innovation.

### **Analysis of Buying a BMW E46 (2003 Facelift) with Heated Left Touring Door Mirror (Part Number: 51167153087)**

#### **Overview**

The BMW E46 (1998 2005) is a well-regarded compact sports sedan known for its driving dynamics, aftermarket support, and cult following. The **2003 facelift model** (M54 engine) is often considered one of the best iterations, offering improved reliability, styling updates, and better equipment options. The **heated left touring door mirror** (part number **51167153087**) is a desirable feature for comfort in cold climates, though it may also indicate a higher-end trim or aftermarket modification.

### **Pros of Buying This Specific E46**

1. **Facelift Improvements (2003 Models)**

- **Engine Updates:** The M54 engine (2.5L or 3.0L) is more refined than the earlier M52, with better power delivery and reliability. The 3.0L (N54) is particularly sought after for its balance of performance and drivability.

- **Interior Upgrades:** Revised dashboard with better materials, improved climate control, and optional leather seats. The facelift also introduced a more modern look with updated grilles and side mirrors.

- **Reliability:** The facelift E46s are generally more reliable than early models, with fewer issues related to the M52 engine s oil consumption and timing chain problems.

- **Aftermarket Support:** The E46 has a massive aftermarket, making modifications (engine swaps, suspension upgrades, interior restyling) relatively straightforward.

2. **Heated Touring Door Mirror (Left Side)**

- **Comfort:** The heated mirror is a practical feature for cold weather, reducing fogging and improving visibility.

- **Aesthetic Appeal:** The touring door mirrors (with integrated turn signals) give the car a more premium, sporty look compared to standard mirrors.

- **Potential Value Indicator:** If the mirror is original, it may suggest the car was equipped with a higher trim (e.g., **M Sport, Touring, or Luxury Package**), which often includes better upholstery, sound systems, and driving dynamics packages.

3. **Driving Experience**

- **Handling:** The E46 is praised for its sharp steering, precise suspension, and engaging driving dynamics, especially in the **M Sport or Sport Package** versions.

- **Performance:** The 3.0L M54 (N54) produces **231 hp** and **229 lb-ft of torque**, offering a good balance of power and efficiency. The 2.5L M54 (N52) is slightly less powerful but still capable.

- **Manual Transmission Option:** If available, the **6-speed manual** is one of the best in its class, offering a more engaging driving experience than the automatic.

4. **Resale Value & Community**

- **Strong Aftermarket:** The E46 has a dedicated fanbase, ensuring parts, tuning, and restoration support remain robust.

- **Classic Status:** While not yet a "classic" in the strictest sense, the facelift E46 is approaching that territory, with prices rising for well-maintained examples.

- **Modification Potential:** Owners can easily upgrade the engine (e.g., **LS swaps, M54 tuning**), suspension (coilovers, sway bars), and interior (restomod builds).

5. **Fuel Efficiency (Compared to Modern Standards)**

- The E46 is far more efficient than most modern muscle cars or SUVs. The **3.0L M54** averages **18 20 MPG city / 25 28 MPG highway**, making it practical for daily use despite its sporty nature.

---

### **Cons of Buying This Specific E46**

1. **Common Issues (Even in Facelift Models)**

- **Timing Chain & Tensioner Wear:** While less severe than in early M52 engines, the M54 s timing chain can stretch over time, leading to rattles or failure. Regular maintenance (chain tensioner replacement) is recommended.

- **Water Pump & Thermostat Failure:** The facelift models improved cooling, but water pumps and thermostats can still fail, leading to overheating. Always check for leaks or excessive coolant consumption.

- **Oil Leaks:** Common from the **valve cover gasket, oil filter housing gasket, or rear main seal**. These are relatively easy to fix but require attention.

- **Suspension Wear:** Front struts, control arms, and bushings can wear out, affecting handling. A pre-purchase inspection should check for excessive play or uneven tire wear.

- **Electrical Gremlins:** The E46 is known for electrical issues, such as **faulty sensors, blown fuses, or intermittent problems with the infotainment system**. The facelift improved reliability, but issues can still arise.

2. **Maintenance Costs**

- **Parts Prices:** While not as expensive as some German cars, BMW parts (especially for the E46) can be costly, especially for rare or aftermarket components.

- **Labor:** If you don t have mechanical experience, labor costs for repairs (e.g., engine work, suspension) can add up.

- **Timing Belt Replacement:** The M54 does **not** require a timing belt (it uses a chain), but related components (water pump, tensioner) should be replaced as a precaution every **60,000 100,000 miles**.

3. **Depreciation & Insurance**

- **Resale Value:** While the E46 holds value better than many contemporaries, it s not a high-depreciation asset. Insurance costs may be higher than for a modern compact car.

- **Theft Risk:** BMWs, including E46s, are sometimes targeted for parts. A garage or security system is advisable.

4. **Comfort & Practicality**

- **Ride Quality:** The E46 is firm off the factory, especially in Sport or M Sport trims. Aftermarket suspension upgrades (lowering springs, coilovers) can improve handling but may reduce comfort.

- **Cargo Space:** While adequate for a coupe, the E46 s trunk is smaller than most modern sedans, making it less practical for large purchases.

- **Heated Mirror Limitations:** The heated mirror is a convenience but not a critical feature. If the car is used in mild climates, this may not be a priority.

5. **Age-Related Concerns**

- **Rust:** Check the **rocker panels, wheel wells, and undercarriage** for rust, especially if the car has seen salt or poor storage conditions.

- **Wear & Tear:** High-mileage examples may have worn **brake pads, tires, or interior components** (seats, dash materials).

- **Recall & Modifications:** Ensure the car hasn t been modified in ways that void warranties or create safety risks (e.g., improper engine swaps, exhaust modifications).

---

### **Key Considerations Before Purchase**

1. **Verify the Mirror s Origin**

- Is the **51167153087** mirror **original** (factory-installed) or **aftermarket**?

- **Original:** Suggests a higher trim level (e.g., **Touring, M Sport, or Luxury Package**). Check for matching numbers and condition.

- **Aftermarket:** Could be a recent addition; ask why it was replaced (e.g., broken, upgraded for style).

- Ensure the mirror is **properly wired** and functions correctly (no intermittent heating issues).

2. **Check the Engine & Transmission**

- **Mileage:** Aim for **under 100,000 miles** for a well-maintained example. **100,000 150,000 miles** is manageable if well-documented.

- **Service History:** Look for **regular oil changes (every 5,000 7,500 miles)**, timing chain/tensioner replacements, and cooling system maintenance.

- **Test Drive:** Listen for **knocks, rattles, or unusual noises** (chain stretch, rod knock). Check for **smooth shifting** (if automatic) or **precise engagement** (if manual).

3. **Inspect the Suspension & Steering**

- **Front End:** Check for **bounciness, wandering, or uneven tire wear** (indicates worn bushings, struts, or control arms).

- **Rear:** The E46 uses a **multi-link rear suspension**; worn bushings can cause handling issues.

- **Steering:** Should be **precise and without play**. Power steering fluid level should be checked.

4. **Electrical System**

- Test all **windows, locks, lights, and sensors** (door ajar, brake lights, turn signals).

- Check the **infotainment system** (if equipped) for glitches or dead pixels.

- Look for **fuse box issues** or **intermittent electrical problems** (common in older BMWs).

5. **Interior Condition**

- **Leather/
