### **Pros and Cons of Buying a 2013 2019 BMW F06 M6/M6 Gran Coupe (650i/640i) with a Faulty Rear Third Brake Light Lamp (Part Number: 9977-09)**

#### **Pros**

1. **Premium Driving Experience**

- The F06 M6 and M6 Gran Coupe are among BMW s most refined and engaging luxury grand tourers. The M6, in particular, delivers a near-supercar-level driving experience with its twin-turbo V8 (650i) or inline-six (640i), offering sharp handling, precise steering, and engaging performance.

- The Gran Coupe s shorter wheelbase and coupe-like stance make it more nimble than a traditional sedan, appealing to enthusiasts who want a mix of luxury and sportiness.

2. **Luxury and Comfort**

- High-quality materials, ergonomic seating, and advanced infotainment (iDrive 6 or 7) provide a premium cabin experience.

- Quiet cabin, smooth ride (especially in comfort mode), and ample legroom make long drives comfortable.

- Available features like adaptive cruise control, parking sensors, and premium audio systems enhance convenience.

3. **Strong Performance and Power**

- The **650i (N63TU)** twin-turbo V8 produces **480 503 hp** (depending on market) and **553 lb-ft of torque**, making it one of the most powerful BMW sedans of its era. The M6 Gran Coupe (when available) pushes this further with **503 hp** and **516 lb-ft**.

- The **640i (N55)** inline-six is more efficient ( 350 hp) but still offers strong acceleration and a sporty feel.

- Both models feature **8-speed automatic transmissions** with smooth shifts and optional manual paddles.

4. **Resale Value and Prestige**

- BMWs, especially M models, hold their value relatively well, though depreciation is still significant over time.

- The M6 badge carries prestige, making it a desirable car for enthusiasts and collectors.

5. **Reliability (Compared to Peers)**

- While no BMW is bulletproof, the **F06 platform (2011 2019)** is generally more reliable than earlier generations (e.g., E65/E66). The **N63 V8** and **N55 inline-six** engines are robust if maintained properly.

- Common issues (like turbocharger failures in older N62s) are less prevalent in the F06.

6. **Aftermarket and Customization**

- The M6 s aggressive styling and performance make it a favorite for aftermarket tuning (exhaust, suspension, wheels).

- BMW s extensive parts availability and tuning community ensure easy modifications.

7. **Safety Features**

- Standard **BMW Safety Personal** suite includes adaptive cruise, lane-keeping assist, and automatic emergency braking.

- Strong crash test ratings (Euro NCAP and IIHS) for its class.

---

#### **Cons**

1. **High Maintenance Costs**

- BMWs are expensive to maintain, with labor costs often **2 3x higher** than mass-market brands.

- The **N63 V8** (650i) is notorious for **turbocharger failures** (especially on high-mileage examples), which can cost **$3,000 $6,000 ** to repair.

- The **N55 inline-six** is more reliable but still requires **timing chain tensioner replacements** ( $1,500 $2,500 at 100K miles).

2. **Common Electrical and Infotainment Issues**

- **iDrive glitches** (freezing, unresponsive screens) are a recurring complaint, often requiring **software updates or ECU resets**.

- **Sensor failures** (e.g., wheel speed sensors, rain sensors) can trigger check engine lights and require diagnostics.

- **Infotainment system crashes** can be frustrating, though newer F06 models (2016 ) have improved stability.

3. **Rear Third Brake Light Lamp (Part 9977-09) A Minor but Annoying Issue**

- While this specific part is a **simple bulb or sensor replacement** (typically **$20 $50** for the bulb labor), a failing rear third brake light can:

- Trigger **check engine lights** (if the system detects a malfunction).

- Be a **safety hazard** (required by law in most regions).

- Annoy the owner if it flickers intermittently.

- **Fix:** Replacing the bulb or recalibrating the sensor is straightforward, but if the issue persists, it may indicate a deeper wiring or module problem.

4. **Fuel Economy and Running Costs**

- The **650i V8** averages **14 16 MPG combined**, making it **less efficient** than a 640i ( 18 20 MPG) or hybrid alternatives.

- High-performance BMWs consume **more premium fuel** (91 octane recommended for N63), increasing long-term costs.

5. **Depreciation and Market Demand**

- While M models hold value better than standard BMWs, they still depreciate ** 50% in 5 years**.

- The **M6 Gran Coupe** is less common than the sedan, which may limit resale options.

- **Luxury car theft risk** is higher than average, so security features (e.g., immobilizer, tracking) are a must.

6. **Potential Hidden Issues**

- **Transmission wear** (especially in high-mileage examples) can lead to **rough shifting or delayed engagement**.

- **Water pump failures** (common in BMWs) can cause **coolant leaks and overheating** ( $1,000 $1,500 to replace).

- **Suspension bushings and struts** wear out ( $1,000 $2,000 for a full rebuild).

- **Carbon buildup in N63 V8s** (after 100K miles) can reduce performance unless the engine is serviced.

7. **Noise and Vibration Issues**

- Some owners report **wind noise** at highway speeds (especially in the Gran Coupe s rear).

- The **N63 V8** can develop **knocking or rattling** from turbocharger or valve train issues.

- **Road noise** is more pronounced than in newer BMWs with improved sound insulation.

8. **Parts and Labor Availability**

- While BMW parts are widely available, **specialty items (e.g., turbochargers, sensors)** can be **expensive or slow to arrive**.

- **Dealer labor rates** are high, making DIY repairs more attractive (but require mechanical skill).

### **Conclusion**

Buying a **2013 2019 BMW F06 M6/M6 Gran Coupe (650i/640i)** is a **high-reward, high-risk proposition**. The car offers an **unmatched blend of luxury, performance, and driving excitement**, making it ideal for enthusiasts who prioritize **experience over practicality**. However, the **high cost of ownership, potential reliability issues, and maintenance demands** mean it s **not a wise choice for budget-conscious buyers or those seeking a hassle-free luxury car**.

The **rear third brake light lamp issue (part 9977-09)** is a **minor but fixable problem** likely just a bulb or sensor replacement but it may signal **underlying electrical quirks** that could require deeper diagnostics. If you re comfortable with **regular maintenance, budgeting for potential repairs, and accepting some trade-offs in reliability**, this BMW can be an incredible car. If you re looking for a **lower-maintenance luxury sedan**, consider alternatives like a **Lexus LS, Audi A8, or Genesis G90**.

---

### **Recommendation**

You **prioritize driving enjoyment** over cost savings.

You **have a maintenance budget** (aim for **$1,500 $3,000/year** for upkeep).

You **prefer a used example with

- Turbocharger health (N63 V8).

- Transmission fluid condition.

- Suspension and bushings.

- Electrical system stability (iDrive, sensors).

You **replace the rear third brake light lamp immediately** and monitor for related issues.

You **can t afford unexpected repairs** (e.g., turbo failure, timing chain).

You **need a reliable, low-maintenance car** (consider a **Lexus, Genesis, or Audi with better long-term reliability**).

You **don t enjoy driving** and prefer a more passive luxury experience.
