### Pros and Cons of Buying a Used Audi A3 (5Q1721117, 2015-2016) S3 with the Brake Pedal Issue

#### **Overview**

The Audi A3 (5Q1721117) from 2015 to 2016, particularly the S3 variant, is a popular performance compact car known for its sporty handling, turbocharged engine, and premium interior. However, like many high-performance vehicles, it has its share of common issues, including problems with the brake pedal assembly. Below is a detailed breakdown of the pros and cons of purchasing one of these models, with a focus on the brake pedal concern.

---

### **Pros**

1. **Performance and Driving Dynamics**

The S3 is equipped with a 2.0L turbocharged four-cylinder engine producing around 300 horsepower and 300 lb-ft of torque, paired with a 7-speed S tronic dual-clutch transmission. This setup delivers strong acceleration and engaging driving dynamics, making it a favorite among enthusiasts. The Quattro all-wheel-drive system enhances traction, especially in spirited driving conditions.

2. **Premium Interior and Build Quality**

Audi s interior is known for its high-quality materials, ergonomic design, and attention to detail. The S3 features a sporty dashboard, leather-trimmed seats, ambient lighting, and advanced infotainment options (including a touchscreen and optional navigation). The build quality is generally solid, though some wear and tear may be present in a used example.

3. **Reliability of the Core Components**

The 2.0L TFSI engine and S tronic transmission are well-regarded for their durability, especially when maintained properly. Many owners report few major issues with these components if the car has been serviced regularly. The suspension and chassis are also praised for their responsiveness and comfort balance.

4. **Resale Value and Brand Prestige**

Audi maintains a strong resale value compared to many competitors, and the S3 s performance-oriented reputation adds to its appeal. Owning an Audi carries prestige, which can be a significant factor for some buyers.

5. **Aftermarket Support and Modifications**

The S3 has a dedicated following, with a wide range of aftermarket parts available for tuning, aesthetics, and performance upgrades. This makes it easier to customize the car to suit individual preferences.

6. **Safety Features**

The S3 comes standard with advanced safety features such as adaptive cruise control, lane-keeping assist, and multiple airbags. These systems enhance safety, particularly in high-performance driving scenarios.

7. **Fuel Efficiency (Relative to Its Class)**

While not a hybrid or diesel, the S3 offers decent fuel efficiency for a turbocharged performance car, typically averaging around 18-22 MPG in the city and 25-30 MPG on the highway, depending on driving conditions.

### **Cons**

1. **Brake Pedal Assembly Issues (Primary Concern)**

The most notable issue with the 2015-2016 Audi A3 S3 is the brake pedal assembly, specifically the **brake pedal return spring and pedal stop**. This problem is well-documented and can manifest in several ways:

- **Stiff or unresponsive brake pedal**: The pedal may feel hard to press or require excessive force to engage the brakes.

- **Pedal stop wear**: The plastic pedal stop can wear out over time, causing the pedal to bottom out or feel loose.

- **Return spring failure**: The spring responsible for returning the pedal to its upright position can break or weaken, leading to a "dead" pedal feel or the pedal not returning fully.

- **Electronic brake system interference**: In some cases, the issue can trigger warning lights (e.g., ABS or brake system warnings) or even cause the car to enter a limited-slip mode.

**Impact**: This issue is not only annoying but can also be a safety concern if it affects the car s braking performance. However, it is relatively easy and inexpensive to fix typically involving the replacement of the pedal stop, return spring, and sometimes the pedal assembly itself. Audi has issued service bulletins and recalls for this issue, and many dealerships and mechanics are familiar with the repair.

2. **Electrical Gremlins**

- **Infotainment system glitches**: The touchscreen or media controls may freeze or malfunction.

- **Sensor failures**: Issues with sensors related to the parking system, ambient lighting, or climate control.

- **Power window or door lock malfunctions**: These are common in many Audi models and can be frustrating but are usually fixable with diagnostics or part replacements.

While these issues are not critical for safety, they can be inconvenient and may require professional attention.

3. **Maintenance Costs**

Audi is a luxury brand, and maintenance can be more expensive than for mainstream competitors. Parts, labor, and diagnostics often cost more, especially if the car requires specialized Audi-trained technicians. Regular maintenance (e.g., oil changes, timing belt replacement, and suspension work) should be budgeted for to avoid costly repairs down the line.

4. **Transmission Issues (Less Common but Possible)**

- **Clutch wear**: The dual-clutch system can experience wear over time, leading to delayed shifts or rough engagement.

- **Software glitches**: Occasional transmission control module (TCM) issues may cause erratic shifting or warning lights.

- **Fluid leaks**: Transmission fluid leaks can occur from gaskets or seals, requiring attention to prevent damage.

These issues are not as widespread as the brake pedal problem but should be checked during a pre-purchase inspection.

5. **Rust and Corrosion**

Depending on the region and climate where the car was driven, rust can be a concern, particularly on the wheel wells, rocker panels, and undercarriage. A thorough inspection of these areas is essential to avoid future corrosion-related repairs.

6. **Depreciation**

While Audi retains value better than many brands, the S3 s performance-oriented nature means it may depreciate faster than standard A3 models. Buyers should be prepared for the possibility of lower resale value over time.

7. **Noise and Vibration**

Some owners report increased road noise or wind noise at higher speeds, particularly with aftermarket wheels or modifications. The cabin can also feel slightly less insulated compared to some competitors.

### **Mitigating the Brake Pedal Issue**

1. **Verify the Problem**: Ask the seller or perform a test drive to confirm whether the brake pedal feels stiff, unresponsive, or bottoms out. Check for any warning lights on the dashboard.

2. **Check Service History**: Ensure the car has been serviced regularly, including brake system inspections. Look for records of brake pedal or stop assembly replacements.

3. **Get a Pre-Purchase Inspection (PPI)**: Hire a trusted mechanic to inspect the brake system, including the pedal assembly, brake lines, and calipers. A PPI can cost around $100-$200 but is a worthwhile investment.

4. **Budget for Repairs**: The brake pedal assembly is relatively inexpensive to fix typically ranging from $150 to $400, depending on whether parts or labor are included. Some dealerships may offer discounts if the issue is covered under a recall or service bulletin.

5. **Consider a Warranty or Extended Coverage**: If possible, arrange for an extended warranty or purchase the car with a warranty that covers the brake system for a set period.

### **Conclusion**

The 2015-2016 Audi A3 S3 is an excellent choice for buyers who prioritize performance, driving enjoyment, and premium features. Its turbocharged engine, Quattro AWD, and sporty handling make it a standout in its class. However, the brake pedal assembly issue is a significant drawback that can detract from the ownership experience if not addressed promptly.

- Budget for the relatively minor but annoying brake pedal repair,

- Address potential electrical or maintenance issues proactively,

- Enjoy the car s performance and driving dynamics,

the S3 remains a compelling purchase. The brake pedal issue is not a dealbreaker but rather a manageable inconvenience that can be fixed quickly and affordably.

- Are unwilling to deal with potential electrical gremlins or maintenance costs,

- Prioritize absolute reliability over performance,

- Cannot afford or do not want to invest in repairs,

the S3 may not be the best choice. In such cases, alternatives like the BMW 435i, Porsche Macan, or even a well-maintained BMW 335i could be worth considering.

### **Recommendation**

1. **Purchase from a reputable dealer or private seller with a clean service history**. Avoid cars with unknown maintenance records.

2. **Inspect the brake system thoroughly** and confirm that the pedal issue is either fixed or that the seller is willing to cover the repair.

3. **Negotiate the price** to account for the brake pedal repair cost. A fair price might be
