What Problems Does the 2009 Audi S4 Have?
Frequently reported problems for the 2009 Audi S4 often revolve around the 3.0L supercharged V6 engine. Carbon buildup on the intake valves is a prevalent issue, leading to reduced performance and potential misfires. Direct injection engines are prone to this, requiring periodic cleaning. The thermostat housing and water pump are also known to fail, leading to coolant leaks and potential overheating. Some owners have reported issues with the DSG transmission, experiencing jerky shifts or failures, although less common. There have been some recalls, primarily related to fuel leaks and airbags, so checking the VIN is advisable. Long-term reliability can be affected by these potential issues, making maintenance history and pre-purchase inspections crucial. Models with higher mileage are more likely to exhibit these problems. Regular oil changes and preventative maintenance, like carbon cleaning, are essential for long-term durability.
How long will the 2009 Audi S4 last?
A well-maintained 2009 Audi S4 can easily reach 150,000 to 200,000 miles or more. Many owners report enjoying their S4s for 10-15 years with proper care. However, long-term durability hinges heavily on maintenance. As mileage increases, issues like carbon buildup, suspension wear, and potential DSG transmission problems (if equipped) become more likely. Neglecting maintenance will significantly shorten its lifespan. Regular oil changes, fluid flushes, and addressing issues promptly are crucial for maximizing longevity. The timing chain tensioner should also be monitored, as failure can lead to catastrophic engine damage.
What Technology & Safety Features are Included?
The 2009 Audi S4 offered a range of technology and safety features for its time. Standard features included Audi Concert audio system with CD player and auxiliary input, automatic climate control, and leather seats. Higher trims added features like a navigation system with real-time traffic updates, a Bang & Olufsen sound system for enhanced audio quality, and Bluetooth connectivity.
Driver-assistance features included optional rear parking sensors and adaptive headlights. The Prestige trim offered blind spot monitoring.
Safety features included standard antilock brakes, stability control, and front, side, and curtain airbags. Optional features included adaptive cruise control.
Crash-test ratings from the IIHS and NHTSA were generally positive, although it's essential to verify specific ratings for the 2009 model year. The NHTSA gave it 4 out of 5 stars for frontal crash protection and 5 out of 5 stars for side crash protection. Some models may also include electronic stability program (ESP) and tire pressure monitoring system (TPMS). While not as advanced as modern cars, the 2009 S4 provided a solid suite of features for its era.

How Does the 2009 Audi S4 Compare to Other Convertible?
The 2009 Audi S4 competed against rivals like the BMW 335i, Mercedes-Benz C350/C350, and Infiniti G37. In terms of performance, the S4's supercharged V6 offered comparable power to the BMW 335i's turbocharged engine, but the BMW might offer a slightly more engaging driving feel for some. The Mercedes C350 offered a more luxurious experience, sacrificing some performance. The Infiniti G37 was often priced more competitively but lacked the refinement of the Audi.
Reliability is a key consideration. The BMW 335i also had its share of potential issues, while the Infiniti G37 was generally considered more reliable. The Mercedes C350 can also have reliability issues.
Feature-wise, the S4 offered a solid blend of luxury and technology. The Audi's Quattro all-wheel drive system gives it an advantage in inclement weather.
Alternatives to consider include the BMW 335i for driving enthusiasts, the Infiniti G37 for a more budget-friendly option, or the Lexus IS350 for improved reliability. The Mercedes C350 can be a good choice if luxury is a primary concern. Ultimately, the best choice depends on individual priorities and preferences.
