Review AUDI Pedal Brake/clutch Oem 8k1 723 523 fits A6 2017

The **Audi 546.AU1U17 Pedal Assembly (Brake/Clutch)** is a precision-engineered component designed exclusively for the **2017 Audi A6 (8K1) models**, specifically tailored to the **723 (Quattro) and 523 (TFSI) variants** with the **7-speed S tronic or dual-clutch DSG transmission**. This high-performance pedal assembly combines the brake and clutch pedals into a single, integrated unit, ensuring seamless integration with the vehicle s advanced driver-assistance systems (ADAS) and electronic stability control (ESC). Crafted from durable, high-grade materials, including reinforced polymer composites and precision-machined steel components, this pedal assembly is engineered to withstand the rigorous demands of daily driving, aggressive acceleration, and frequent braking common in both urban and highway scenarios. The design incorporates a **modular mounting system** that aligns perfectly with the **Audi 8K1 platform s under-dash architecture**, allowing for a clean, interference-free installation that preserves the vehicle s factory aesthetics while enhancing functionality. The brake pedal features a **linear hydraulic response**, providing consistent pedal feel and precise modulation for optimal braking performance, while the clutch pedal (where applicable) is optimized for smooth, progressive engagement, reducing wear on the transmission and reducing the risk of clutch slippage. This component is a direct-fit replacement, ensuring compatibility with the **2017 model year s wiring harness and pedal position sensors**, including the **pedal position sensor (PPS) and brake master cylinder interface**, which are critical for the vehicle s electronic throttle control (ETC) and anti-lock braking system (ABS). Whether used in a routine maintenance upgrade or as part of a full under-dash restoration, this pedal assembly delivers the reliability and performance expected from Audi s high-end engineering, ensuring a seamless driving experience with every press of the brake or clutch.

### **Pros and Cons of Buying a 2017 Audi A6 (8K1, 723.523) with a 546.AU1U17 Pedal Brake/Clutch System**

1. **Reliability of the 3.0L TFSI Engine (BAYH0)**

- The 3.0L turbocharged inline-six (BAYH0) in the 2017 A6 is a well-regarded engine known for its durability, smooth power delivery, and good fuel efficiency for its class. It is less prone to major issues compared to some other Audi engines from that era.

- With proper maintenance, it can easily exceed 200,000 miles without major problems.

2. **Quattro All-Wheel Drive System**

- The Quattro system is robust and reliable, providing excellent traction and stability in various driving conditions. It is less likely to fail catastrophically compared to some aftermarket AWD setups.

3. **Electronic Pedal Brake/Clutch (546.AU1U17)**

- The electronic clutch and brake pedal system (common in Audi s "Drive Select" models) eliminates the need for a traditional hydraulic clutch linkage, reducing wear and tear on the clutch itself. This system is generally reliable if the underlying components (like the clutch actuator and hydraulic system) are in good condition.

- The electronic clutch can be more responsive and precise, especially in stop-and-go traffic, as it adjusts engagement smoothly.

4. **Modern Infotainment and Driver Assistance**

- The 2017 A6 comes with Audi s MMI infotainment system (often paired with a touchscreen and voice control), which is user-friendly and integrates well with navigation, media, and connectivity features.

- Advanced driver-assistance systems (like adaptive cruise control, lane-keeping assist, and traffic sign recognition) are standard or available as options, adding safety and convenience.

5. **Comfortable and Refined Ride**

- The A6 is known for its plush suspension tuning, making it a comfortable car for both city driving and highway cruising. The cabin is well-insulated, reducing road noise.

6. **Resale Value**

- Audi s A6 retains a relatively strong resale value compared to some competitors, especially in its premium sedan segment. This means you may recover a significant portion of your investment if you decide to sell later.

7. **Availability of Parts and Service Support**

- As a relatively recent model (pre-2020), parts for the 2017 A6 are widely available, and Audi dealerships (as well as independent shops) have experience working on this generation. This makes repairs and maintenance more straightforward.

---

1. **Electronic Clutch Potential Issues**

- **Clutch actuator failure**: The motorized clutch actuator can wear out or fail, requiring replacement (a costly repair, often $1,000 $2,000).

- **Hydraulic clutch system leaks**: The electronic clutch relies on hydraulic pressure, and leaks in the system can cause erratic engagement or complete failure.

- **Software glitches**: Occasionally, the system may experience software-related issues, such as the clutch not disengaging properly or the pedal feeling unresponsive. These can sometimes be fixed with a dealer update but may require a trip to the service center.

- If the clutch actuator or hydraulic system is already failing, this could be a significant upfront cost to address.

2. **Higher Maintenance and Repair Costs**

- Audi is a premium brand, and maintenance (oil changes, timing belt, suspension work, etc.) is more expensive than for mainstream brands. The 3.0L TFSI engine requires timely oil changes (every 10,000 15,000 miles) to prevent sludge buildup, which can lead to engine issues if neglected.

- The timing belt and water pump should be replaced around 100,000 miles (though some owners extend this to 120,000 miles with proper maintenance). Failing to do so can cause catastrophic engine damage.

3. **Electrical Gremlins**

- Faulty sensors (e.g., camshaft or crankshaft position sensors).

- Infotainment system freezes or software errors.

- Window regulator failures.

- Heating/cooling system malfunctions (e.g., faulty blower motors or climate control actuators).

- These issues can be frustrating and costly to repair, often requiring dealer-level diagnostics.

4. **Suspension Wear and Tear**

- Worn-out struts or shock absorbers (typically need replacement every 80,000 120,000 miles).

- Bushings and control arm wear, which can lead to clunking noises and poor handling.

- Air suspension leaks (if equipped), which can be expensive to repair.

5. **Transmission (If Equipped with 8-Speed Tiptronic)**

- Delayed shifting or rough transitions (often due to worn valve bodies or solenoids).

- Transmission fluid leaks (common at the pan gasket or seals).

- Electronic control module failures, which may require reprogramming or replacement.

- Transmission repairs can be costly, especially if the fluid has never been changed (recommended every 60,000 100,000 miles).

6. **Interior Quality and Durability**

- While the A6 s interior is luxurious, some materials (like plastic trim) can feel cheap or prone to scratches. The seats, while comfortable, may not be as durable as those in higher-end Audi models (e.g., S6 or A8).

- The infotainment system s touchscreen can be sensitive to fingerprints and may require occasional recalibration.

7. **Depreciation**

- Like most Audis, the A6 loses value quickly. If you plan to keep the car long-term, depreciation may not be a major concern, but if you re looking for a low-cost used car, the A6 may not offer the best value compared to other luxury sedans (e.g., BMW 5 Series, Mercedes E-Class).

8. **Potential for Hidden Issues**

- **Exhaust manifold leaks** (common in the 3.0L TFSI, leading to check engine lights and reduced performance).

- **Oil leaks** (valve cover gasket, oil filter housing gasket).

- **Coolant leaks** (water pump, thermostat housing).

- **Turbocharger wear** (if the car has high mileage, the turbo may need replacement).

- These issues can add up quickly and may not be immediately obvious to an untrained eye.

---

The **2017 Audi A6 (8K1, 723.523) with the 3.0L TFSI engine and electronic clutch (546.AU1U17)** is a solid choice for buyers who prioritize comfort, refinement, and Quattro reliability. It offers a smooth driving experience, good fuel economy for its class, and modern features. However, the **electronic clutch system introduces complexity and potential higher repair costs**, particularly if the clutch actuator or hydraulic components fail. Additionally, Audi s reputation for electrical and maintenance expenses means that budgeting for unexpected repairs is wise.

If you re comfortable with the trade-offs (higher maintenance costs, potential clutch issues, and electrical quirks), this A6 can be a great long-term vehicle especially if it has been well-maintained. However, if you re looking for a more straightforward or budget-friendly luxury sedan, you may want to consider alternatives like a **BMW 5 Series (F10/F11) or Mercedes E-Class (W212/W213)**, which may have simpler clutch systems and slightly lower repair costs in some cases.

- Hire a trusted mechanic or Audi specialist to thoroughly inspect the clutch actuator, hydraulic system, transmission, engine, and suspension. This will help identify any hidden issues before you commit to the purchase.

- Ensure the car has had regular oil changes, timing belt/water pump replacements (if due), and transmission fluid changes. A well-documented service history is a strong indicator of reliability.

- Pay attention to how the electronic clutch engages and disengages. Any hesitation, grinding, or unusual noises could signal trouble.

- Test the transmission for smooth shifting and responsiveness. Delayed or rough shifts may indicate transmission wear.

- Set aside funds for potential clutch actuator replacement ( $1,000 $2,000), transmission fluid refresh ( $300 $600), and suspension work ( $
