### Pros and Cons of Buying a 2017 Audi A7 (W12) with the Center High-Mount Stop Lamp (CHMSL) Part Number 1797191

#### **Pros**

1. **Premium Brand and Build Quality**

Audi is known for its high-quality materials, refined interiors, and robust engineering. The A7, in particular, offers a luxurious and well-crafted cabin with premium finishes like leather, wood, or aluminum trim, depending on the trim level. The build quality is generally excellent, with tight tolerances and a quiet, well-insulated cabin.

2. **Strong Performance and Handling**

The 2017 A7 is available with a range of powerful engines, including the **3.0L V6 (333 hp)** and the **3.0L Twin-Turbo V6 (382 hp)** in the S line. The S line also features a **7-speed S tronic dual-clutch transmission**, which provides smooth and responsive shifts. The A7 s handling is precise, with a well-tuned suspension that balances comfort and sportiness. The optional **quattro all-wheel-drive system** enhances traction and stability, especially in adverse conditions.

3. **Spacious and Practical Interior**

The A7 is one of Audi s most spacious models, offering a **large cabin** with ample legroom for both front and rear passengers. The **rear seats fold flat** (1.5:1 ratio) to provide significant cargo space, making it practical for road trips or moving items. The **panoramic sunroof** (available on higher trims) adds to the sense of openness and luxury.

4. **Advanced Technology and Infotainment**

The A7 comes with Audi s **MMI (Multi Media Interface) system**, which integrates seamlessly with the **Virtual Cockpit** (digital instrument cluster) and **quattro dashboard** (on higher trims). The **8.0-inch touchscreen** (or larger in premium trims) supports **Apple CarPlay and Android Auto**, and the **Audi connect** system provides navigation, traffic updates, and remote access via a smartphone app. The **premium sound system** (up to 12 speakers) delivers high-quality audio.

5. **Safety Features**

The 2017 A7 includes a comprehensive suite of **safety technologies**, such as:

- **Adaptive Cruise Control (ACC)**

- **Lane Keeping Assist (LKA)**

- **Blind Spot Monitoring (BSM)**

- **Rear Traffic Alert**

- **Automatic Emergency Braking (AEB)**

- **Multiple airbags** (front, side, and curtain)

The **Center High-Mount Stop Lamp (CHMSL)** you mentioned is a standard safety feature on many Audi models, improving visibility from the rear, which is particularly useful in traffic or when merging.

6. **Comfort and Ride Quality**

The A7 is designed for both city and highway driving. The **adjustable air suspension** (on higher trims) allows for customizable ride height and firmness, improving comfort on rough roads while maintaining stability at high speeds. The **quiet cabin** is a hallmark of Audi s engineering, thanks to excellent sound insulation.

7. **Resale Value**

Audi vehicles, especially well-maintained ones, hold their value relatively well. The A7, in particular, is a popular model, so finding parts and maintaining it long-term should not be a major issue.

8. **Exclusive Design and Brand Prestige**

The A7 s **coupe-like roofline** and **sleek, aerodynamic design** set it apart from competitors like the BMW 5 Series or Mercedes E-Class. Owning an Audi carries a sense of prestige and exclusivity, which many buyers appreciate.

#### **Cons**

1. **High Cost of Ownership**

Audi vehicles are **expensive to purchase**, and maintenance costs can be **significantly higher** than those of Japanese or Korean brands. Common issues like **timing chain stretch, water pump failure, and electrical gremlins** can lead to costly repairs. The **3.0L Twin-Turbo V6 (used in the S line)** is known to have **oil consumption issues** and **carbon buildup on intake valves**, which may require additional maintenance.

2. **Complex and Expensive Repairs**

Audi s advanced technology and proprietary systems (e.g., **MMI, quattro, adaptive suspension**) mean that repairs can be **time-consuming and costly**. Independent mechanics may not have the expertise or tools to diagnose issues quickly, forcing owners to rely on **dealer service**, which is more expensive.

3. **Electrical System Issues**

Many Audi owners report **electrical problems**, such as:

- **Faulty sensors** (e.g., camshaft position sensor, oil level sensor)

- **Intermittent issues with infotainment or climate control**

- **Power window or door lock malfunctions**

These issues can be frustrating and may require **multiple visits to the dealership**.

4. **Fuel Economy Concerns**

While the A7 is efficient for its class, the **V6 engines (especially the turbocharged ones) consume more fuel** compared to smaller, more efficient alternatives (e.g., a BMW 3 Series or Lexus ES). The **S line models** are particularly thirsty, with **MPG ratings in the low 20s (city) and mid-20s (highway)** for gasoline.

5. **Depreciation**

While Audi holds value better than some brands, the A7 still **depreciates significantly** over time. If you plan to keep the car long-term, the initial purchase price may not be fully recovered when selling.

6. **Potential Reliability Issues with the 3.0L Twin-Turbo V6**

The **S line s 3.0L Twin-Turbo V6** has a reputation for **oil consumption, carbon buildup, and timing chain wear**. Some owners report **excessive oil burning**, requiring frequent top-ups. If not addressed, this can lead to **engine damage**. A **carbon cleaning procedure** (around $500 $800) is often recommended to prevent valve issues.

7. **Limited Practicality for Some Buyers**

While the A7 is spacious, its **coupe-like roofline** means **less headroom** compared to a sedan. Some taller drivers or passengers may find the rear seats **less comfortable** than in a traditional sedan. Additionally, the **lack of a rear hatch** (unlike the A6 or A8) makes loading bulky items slightly more cumbersome.

8. **Noise and Vibration Issues**

Some owners report **wind noise** at high speeds, particularly with the **panoramic sunroof**. The **gearbox (especially in the S tronic dual-clutch transmission)** can also produce **unusual noises** during shifting, though this is not universal.

9. **Software and Infotainment Glitches**

Audi s **MMI system** can be **slow or unresponsive** at times, and updates may introduce new bugs. The **Virtual Cockpit** is a great feature, but some users find it **overwhelming or difficult to navigate** compared to simpler displays.

10. **Competition from Other Luxury Brands**

The A7 competes directly with models like the **BMW 5 Series, Mercedes E-Class, and Lexus GS**. While the A7 offers a **more premium feel**, some buyers may prefer the **more practicality of a BMW or the reliability of a Lexus**.

---

### **Ending Conclusion**

The **2017 Audi A7 with the Center High-Mount Stop Lamp (CHMSL)** is a **luxurious, well-built, and capable luxury sedan** that excels in performance, comfort, and technology. It is an excellent choice for buyers who prioritize **brand prestige, driving dynamics, and a refined interior**. However, it comes with **higher ownership costs, potential reliability concerns (particularly with the S line s turbo engine), and complex maintenance requirements**.

If you are **financially prepared for the long-term costs** and **not overly concerned about fuel efficiency or resale depreciation**, the A7 is a **strong contender** in the luxury sedan market. On the other hand, if **reliability, lower maintenance costs, or better fuel economy** are top priorities, you may want to consider alternatives like a **BMW 5 Series, Lexus GS, or a well-maintained Mercedes E-Class**.

---

### **Recommendation**

**Buy the 2017 Audi A7 if:**

- You have a **budget for maintenance and potential repairs**.

- You **prioritize driving enjoyment, luxury, and Audi s brand prestige**.

- You **need a spacious, tech-rich sedan** with strong performance.

- You **plan to keep the car for 5 7 years** and can afford the depreciation.

**Avoid or Consider Alternatives if:**

- You **want lower long-term costs** (consider a Lexus GS or BMW 5 Series with a proven engine).

- You **are sensitive to fuel expenses** (the S line s turbo V6 is less efficient).

- You **prefer a more reliable brand** with fewer reported electrical or engine issues.

- You **need maximum practicality** (the A6 or A8 may offer better cargo space).

**Before Purchasing:**

- **Get a pre-purchase inspection** from a **trusted Audi specialist** to
