The Audi RS7 Sportback, produced between 2013 and 2019, is a powerhouse in a sleek, four-door coupe design. Packed with a twin-turbocharged 4.0L V8 engine and Quattro all-wheel drive, it combines luxury, practicality, and breathtaking performance. However, no car is without flaws, and the RS7 is no exception. In this detailed article, we explore the most common problems reported by RS7 owners, offer buying advice, and examine the costs of owning this high-performance machine.
Common Problems with the 2013-2019 Audi RS7 Sportback
1. Oil Consumption Issues
The 4.0L TFSI V8 engine in the RS7 is known for delivering incredible performance, but it also has a reputation for excessive oil consumption. Some owners report the need to add oil between scheduled services, which can be both inconvenient and concerning.
- Causes: This issue is often linked to worn piston rings or faulty PCV (Positive Crankcase Ventilation) valves. In high-performance engines like the RS7's, increased stress can exacerbate these issues.
- Symptoms: Frequent low-oil warnings, blue smoke from the exhaust (indicating burning oil), and reduced fuel efficiency.
Solutions: Addressing excessive oil consumption can be costly. Replacing piston rings requires a major engine overhaul, while PCV valve replacement is a more manageable repair. Regular oil checks and timely servicing can help mitigate further damage.
2. Turbocharger Failures
The twin-turbochargers in the RS7 are key to its exhilarating power output, but they are also a point of vulnerability. Turbo failures are not uncommon, particularly in higher-mileage vehicles.
- Causes: Carbon buildup in the intake system, oil starvation, or poor-quality oil are common culprits. Prolonged high-temperature operation without proper cooldown periods can also strain the turbos.
- Symptoms: Loss of power, excessive exhaust smoke, whining or screeching noises from the engine, and a noticeable drop in acceleration performance.
Solutions: Replacing turbochargers can be a significant expense, often running into thousands of dollars. Preventive measures include regular oil changes with high-quality synthetic oil and ensuring proper engine cooldown after spirited driving.
3. Carbon Buildup in the Intake System
Like many direct-injection engines, the RS7's V8 is prone to carbon buildup on the intake valves. Over time, this can lead to reduced engine performance, misfires, and poor fuel economy.
- Causes: Direct injection sprays fuel directly into the combustion chamber, bypassing the intake valves. Without the "cleaning" effect of fuel passing over them, oil vapors and contaminants accumulate.
- Symptoms: Rough idling, hesitation during acceleration, and a noticeable loss of power.
Solutions: Walnut blasting (a process where crushed walnut shells are used to clean the valves) is the most effective method for addressing carbon buildup. This service is recommended every 50,000 to 60,000 miles for optimal performance.
4. Suspension Wear and Air Suspension Issues
The RS7 often comes equipped with adaptive air suspension, which enhances ride comfort and handling. However, the complexity of this system makes it susceptible to wear and malfunction.
- Common Issues: Air suspension leaks, failed compressors, or control module errors.
- Symptoms: Uneven ride height, a bouncy or overly stiff ride, and warning lights on the dashboard.
Solutions: Repairing or replacing air suspension components can be expensive. Some owners opt for aftermarket solutions, such as conventional coilover suspensions, to reduce costs.
5. Transmission Problems
The RS7 is equipped with an 8-speed ZF automatic transmission, known for its smooth and quick shifts. However, some owners have reported issues, particularly with the transmission's mechatronic unit (the electronic control system).
- Symptoms: Delayed gear changes, rough shifts, or transmission slippage. In severe cases, the vehicle may enter "limp mode," restricting performance.
- Causes: Electronic faults, fluid degradation, or internal wear.
Solutions: A transmission fluid change every 40,000-60,000 miles can help prevent issues. If problems persist, replacing the mechatronic unit or rebuilding the transmission may be necessary, both of which are costly repairs.
6. Brake Wear and Warping
Given the RS7's weight and performance capabilities, its brakes endure significant stress, particularly during spirited driving.
- Common Problems: Premature brake pad wear, rotor warping, and uneven braking performance.
- Symptoms: Vibrations or pulsing during braking, squeaking noises, or reduced stopping power.
Solutions: Regular inspection and replacement of brake pads and rotors are crucial. Upgrading to high-performance aftermarket components can improve longevity and performance but at a higher cost.
7. Electrical and Software Issues
Luxury vehicles like the RS7 are equipped with advanced electronics, but these systems can sometimes be a source of frustration.
- Reported Problems: Malfunctioning infotainment systems, erratic behavior of the adaptive cruise control, and occasional warning lights for parking sensors or driver-assistance systems.
- Causes: Software bugs, wiring faults, or sensor failures.
Solutions: Many electrical issues can be resolved with software updates or reprogramming. Regular diagnostic checks can help identify and address issues early.
Buying Tips: What to Look for in a Used Audi RS7 Sportback (2013-2019)
- Service History: A comprehensive service record is essential. Look for evidence of regular oil changes, turbocharger inspections, and carbon cleaning.
- Pre-Purchase Inspection: Hire a qualified mechanic to perform a thorough inspection, focusing on the engine, transmission, suspension, and brakes.
- Test Drive: During the test drive, pay attention to the transmission's smoothness, braking performance, and any unusual noises from the engine or suspension.
- Recall Compliance: Check if all recalls have been addressed, particularly those involving the software or safety systems.
- Modifications: Beware of heavily modified RS7s, as aftermarket performance upgrades can increase wear and strain on critical components.
Cost of Ownership: How Expensive Is the Audi RS7 Sportback to Own?
Fuel Costs
With a combined fuel economy of around 20-22 MPG, the RS7 is not fuel-efficient, especially if driven aggressively. Expect high fuel costs, particularly if premium-grade gasoline is required.
Maintenance and Repairs
- Oil Changes: High-performance synthetic oil changes cost between $200 and $400, depending on the service provider.
- Tires: Replacing all four tires can cost $1,000-$2,000, depending on the brand and specifications.
- Brake Maintenance: High-performance brake pads and rotors can cost $2,000-$3,500 per axle.
- Major Repairs: Turbocharger replacements or air suspension repairs can exceed $5,000-$8,000.
Insurance and Depreciation
- Insurance Costs: Due to its high value and performance, the RS7 has above-average insurance premiums, typically ranging from $1,500 to $2,500 annually.
- Depreciation: While the RS7 retains value better than many vehicles, it still depreciates significantly within the first five years.
Conclusion
The Audi RS7 Sportback (2013-2019) is an exhilarating blend of luxury and performance, but owning one requires careful consideration of its potential pitfalls. From turbocharger and oil consumption issues to suspension and electrical challenges, understanding these common problems is key to making an informed decision. By prioritizing regular maintenance and thorough inspections, you can enjoy the RS7’s thrilling capabilities while minimizing surprises down the road.
