The Audi A5 Sportback, introduced in 2009, brought together elegance, performance, and practicality in a sleek, coupe-like design. Known for its luxurious interior, strong engines, and cutting-edge technology, it remains a popular choice among those who appreciate German engineering in a stylish package. However, the 2009 A5 Sportback, like many premium cars, has its share of issues, especially as it ages.
This article will delve into the most common problems reported by 2009 Audi A5 Sportback owners, offering a comprehensive guide to potential concerns, what to check when buying a used model, and how expensive it is to maintain. If you're considering purchasing this model, this guide will help you make an informed decision.
Introduction: The 2009 Audi A5 Sportback
The Audi A5 Sportback blends the sophistication of a coupe with the practicality of a sedan, making it an attractive option for those who seek a balance of style and function. Available with a range of engines, including the well-regarded 2.0-liter TFSI and the more powerful V6, the A5 Sportback promises a blend of performance and luxury. However, after more than a decade, some issues have emerged that prospective buyers should be aware of.
Common Problems with the 2009 Audi A5 Sportback
1. Oil Consumption Issues (2.0 TFSI Engine)
One of the most frequently reported problems with the 2009 Audi A5, particularly in models equipped with the 2.0-liter TFSI engine, is excessive oil consumption. Many owners have experienced the need to top up the oil frequently between services, sometimes every 500 to 1,000 miles.
This issue stems from piston ring wear and turbocharger seals, which can cause oil to burn off more quickly than expected. Audi addressed this problem in later models with updated piston rings, but early versions of the A5 Sportback are prone to this issue.
Symptoms of oil consumption include:
- Frequent oil warning light on the dashboard.
- Noticeably low oil levels between oil changes.
- Possible blue smoke from the exhaust under heavy acceleration.
Fixing this problem can be expensive, often requiring piston ring replacements, which involve significant labor costs. Audi did issue service bulletins and even covered some repairs under warranty, but for older models, owners may bear the full cost.
2. Timing Chain Tensioner Failure
Another serious issue affecting the 2009 Audi A5 is timing chain tensioner failure, especially in models with the 2.0 TFSI engine. The timing chain system is responsible for keeping the engine's internal components in sync. If the tensioner fails, it can lead to catastrophic engine damage.
Signs of timing chain tensioner problems include:
- Rattling noise from the engine, especially at cold startup.
- Check engine light and misfiring, particularly if the timing is off.
- Difficulty starting the engine, especially in colder conditions.
If not addressed, a failed tensioner can result in the timing chain slipping, potentially causing valves to collide with the pistons, which can destroy the engine. Replacing the timing chain and tensioner is an expensive job, often costing several thousand dollars, but it is essential for the long-term health of the engine.
3. Carbon Buildup on Intake Valves
As with many direct-injection engines, the 2009 Audi A5’s FSI engines are prone to carbon buildup on the intake valves. Over time, carbon deposits can accumulate on the intake valves, restricting airflow and affecting engine performance.
Common symptoms of carbon buildup include:
- Rough idle or misfires, especially during cold starts.
- Reduced power and throttle response.
- Check engine light with misfire codes.
The only effective way to clean these deposits is through a walnut blasting procedure, where the intake manifold is removed, and the valves are cleaned with walnut shells to clear away the carbon. This service is typically required every 50,000 to 70,000 miles and can be quite costly.
4. Power Steering Pump Failure
Owners of the 2009 Audi A5 Sportback have also reported issues with the power steering pump. Over time, the power steering system can develop leaks or the pump itself can fail, leading to a loss of power assistance.
Signs of power steering issues include:
- Whining noise when turning the steering wheel.
- Heavier steering feel, especially at low speeds.
- Leaking power steering fluid under the vehicle.
While power steering issues are not uncommon in older vehicles, replacing the pump or fixing leaks can be expensive, particularly if the entire power steering rack needs to be replaced.
5. Transmission Problems (S Tronic/DSG)
The S Tronic (DSG) dual-clutch transmission found in many A5 Sportbacks is praised for its quick and smooth shifts, but it is also known for developing issues over time. Some common problems include:
- Jerky shifting or delayed gear engagement, especially at low speeds or when the car is cold.
- Clutch wear, which can result in slipping or difficulty shifting.
- Mechatronic unit failure, which can cause erratic shifting or prevent the car from going into gear.
The S Tronic transmission requires regular fluid changes to maintain its longevity. If neglected, repairs can be costly, particularly if the clutches or mechatronic unit need replacement.
6. Electrical Issues
As with many luxury vehicles, the 2009 Audi A5 can develop electrical gremlins as it ages. Some of the most common electrical issues include:
- Failing window regulators, where the windows may stop working or get stuck in one position.
- Electronic control unit (ECU) malfunctions, leading to warning lights on the dashboard.
- Problems with the MMI infotainment system, such as freezing or not turning on.
While some of these issues may be minor inconveniences, fixing electrical components in luxury cars like the Audi A5 can become expensive, especially if the ECU or complex electronics are involved.
What to Look for When Buying a 2009 Audi A5 Sportback
If you're in the market for a used 2009 Audi A5 Sportback, it's crucial to thoroughly inspect the vehicle to avoid potential headaches down the road. Here’s what to look for:
- Service History: Ensure the car has a full service history, especially for major services like timing chain replacement, oil consumption fixes, and regular transmission fluid changes.
- Cold Start Test: Listen for any rattling sounds during a cold start, as this could indicate timing chain tensioner issues.
- Check for Oil Consumption: Ask the seller about oil consumption and whether any repairs (such as piston ring replacements) have been done.
- Transmission Performance: During the test drive, pay attention to how smoothly the transmission shifts, especially at low speeds. Any jerking or delayed shifts could be a sign of S Tronic transmission issues.
- Power Steering: Check for whining noises or heavy steering, which could indicate power steering pump problems.
- Carbon Buildup: If the car has high mileage, inquire if any intake cleaning services (such as walnut blasting) have been performed to address carbon buildup.
How Expensive is it to Own a 2009 Audi A5 Sportback?
The Audi A5 Sportback is a luxury vehicle, and as such, its ownership costs are higher than average. Here’s what to consider:
- Fuel Costs: Depending on the engine, fuel consumption can be relatively high, especially if you opt for the more powerful V6 engines. Expect fuel economy in the range of 20-28 MPG.
- Maintenance: Routine maintenance, such as oil changes, brake servicing, and tire replacement, is typical for a premium car and can be more expensive than mainstream models. Expect to pay higher labor rates at dealerships or specialized repair shops.
- Repairs: Major repairs, such as timing chain tensioner replacement, transmission repairs, or fixing oil consumption issues, can be costly. Repairing or replacing the timing chain tensioner alone can cost over $2,000, and fixing oil consumption issues can exceed that.
- Insurance: Insurance premiums for the Audi A5 are higher than average due to its luxury status and performance capabilities. Be sure to compare quotes to find the best rate.
Conclusion
The 2009 Audi A5 Sportback offers a blend of luxury, performance, and style that is hard to beat. However, as with any aging luxury vehicle, it comes with its share of common problems, including oil consumption, timing chain tensioner failures, carbon buildup, and transmission issues. These problems can lead to expensive repairs, so it’s essential to be aware of them when considering buying a used A5.
If you’re set on owning one of these beautiful cars, look for a well-maintained model with a full service history, and be prepared for higher maintenance costs. With proper care and attention, the Audi A5 Sportback can still provide an enjoyable and refined driving experience for years to come.
