The 2008 Audi S4 is a performance-oriented variant of the A4, known for its blend of luxury and spirited driving. It's available as a sedan, Avant (wagon), and Cabriolet (convertible). The B7 generation S4, which includes the 2008 model year, was produced from 2005-2009. Key trims include the base S4, and notable packages with added features. The original MSRP ranged from approximately $47,000 to $55,000 depending on the body style and options. Its popularity stems from its powerful V8 engine, standard Quattro all-wheel drive, and refined interior.
The Good
The 2008 Audi S4 offers a compelling blend of advantages. Its high-revving V8 provides exhilarating performance, appealing to emotional buyers. Quattro all-wheel drive delivers confident handling in all weather conditions. The comfortable and well-appointed interior offers a premium experience. While not the most fuel-efficient, its value on the used market is attractive to practical buyers seeking performance at a reasonable price.
The Bad
Potential weaknesses of the 2008 Audi S4 include higher running costs due to its V8 engine and potential for mechanical issues. Common problems involve timing chain tensioners, carbon buildup on the intake valves, and electrical glitches. The complex all-wheel-drive system can also be expensive to maintain. Thorough pre-purchase inspections are crucial.

What Problems Does the 2008 Audi S4 Have?
The 2008 Audi S4, like many performance vehicles, has some frequently reported problems and long-term reliability concerns. One of the most significant and costly issues is related to the 4.2L V8 engine's timing chain tensioners. These can wear down over time, leading to potential timing chain failure, which is a major engine repair. Carbon buildup on the intake valves is another common issue, particularly in direct-injection engines like this one. This can reduce performance and fuel economy.
Electrical gremlins, such as issues with the infotainment system, power windows, and central locking, are also relatively common. The early B7 S4 models (2005-2006) are sometimes reported to have slightly more issues with the electronic stability program (ESP) system. The Quattro all-wheel-drive system, while robust, requires regular maintenance and can be expensive to repair if neglected. It's crucial to check for any signs of differential leaks or unusual noises.
While specific recalls for the 2008 Audi S4 can vary depending on the region, it's important to check the NHTSA (National Highway Traffic Safety Administration) website or Audi's recall database for any outstanding safety recalls related to the vehicle's VIN. Given the age of the vehicle, pre-purchase inspections are essential to assess the condition of these known problem areas.

How long will the 2008 Audi S4 last?
Given the age of the 2008 Audi S4, most examples will have accumulated significant mileage. A well-maintained S4 could easily surpass 150,000 miles or even 200,000 miles. However, longevity heavily depends on consistent maintenance, including regular oil changes, timing chain service (if not already addressed), and attention to the cooling system.
Long-term durability weaknesses revolve around the aforementioned timing chain issue, carbon buildup, and wear on suspension components. Rubber bushings and seals throughout the car will likely need replacement over time. The interior, while generally well-built, may show wear on the leather seats and trim pieces.

Rubber bushings and seals throughout the car will likely need replacement over time. The interior, while generally well-built, may show wear on the leather seats and trim pieces.
What Technology & Safety Features are Included?
The 2008 Audi S4 offered a decent array of technology and safety features for its time. Standard tech included a premium sound system with a CD player, dual-zone automatic climate control, and power-adjustable front seats. Optional features included a navigation system with a screen integrated into the dashboard, a Bose sound system upgrade, and rear parking sensors.
Driver-assistance features were relatively limited compared to modern cars. Rear parking sensors were an available option, but more advanced systems like adaptive cruise control or lane departure warning were not offered. Safety features included standard xenon headlights, anti-lock brakes (ABS), electronic stability program (ESP), and multiple airbags (front, side, and curtain airbags).
The NHTSA (National Highway Traffic Safety Administration) and IIHS (Insurance Institute for Highway Safety) crash-test ratings for the 2008 Audi S4 (and closely related A4) were generally good. The IIHS gave the A4 (which shares a similar structure) a 'Good' rating in most crash tests. NHTSA ratings can vary depending on the specific test and model year, so consulting their website for specific data is recommended. The S4 benefitted from Audi's Quattro all-wheel drive, enhancing stability and traction in adverse conditions.

2008 Audi S4 Prices and Market Value
When new, the 2008 Audi S4 had an MSRP ranging from approximately $47,000 to $55,000 depending on the body style (sedan, Avant, Cabriolet) and options. Current used market prices vary greatly depending on condition, mileage, and location. Expect to find examples ranging from around $8,000 to $18,000 or more for exceptionally well-maintained, low-mileage examples.
The S4 has depreciated significantly due to its age and potential maintenance costs. Factors affecting resale value include the vehicle's condition (especially the engine and timing chain status), mileage, service history, and whether it's a desirable body style (Avant models often hold their value slightly better). A clean title and lack of modifications also enhance resale value.

2008 Audi S4 Cost of Ownership
The 2008 Audi S4 is generally considered a costly vehicle to own in the long term. Insurance costs can be higher than average due to its performance nature. Fuel economy is relatively poor (around 13-20 mpg), leading to higher fuel expenses. Maintenance and repair costs are also elevated, particularly if issues like timing chain problems or all-wheel-drive system repairs arise. Regular maintenance, while crucial, can be more expensive than for a standard A4. Budgeting for potential repairs is essential when considering a used S4.

How Does the 2008 Audi S4 Compare to Other Convertible?
The 2008 Audi S4 competed against vehicles like the BMW 335i/M3, Mercedes-Benz C350/C55 AMG, and Infiniti G37. In terms of performance, the S4's V8 offered a unique sound and power delivery compared to the BMW 335i's turbocharged inline-six. The BMW M3 offered superior handling and performance, but at a higher price point. The Mercedes-Benz C55 AMG provided similar V8 power but with a different driving experience.
Regarding features, the S4 was generally well-equipped, but some rivals offered more advanced technology options. Reliability is where the S4 lags somewhat behind the BMW 335i and Infiniti G37, especially concerning the timing chain issues. Price-wise, the S4 occupies a competitive space on the used market, often offering a good value proposition for its performance level.
Alternatives to consider include the BMW 335i (for a balance of performance and reliability), the Infiniti G37 (for value and reliability), or a newer Audi S3 (for more modern technology and potentially better reliability). For ultimate performance, the BMW M3 remains a strong contender, but at a higher price. The choice depends on individual priorities and budget.

Final Verdict: Is the 2008 Audi S4 a Good Convertible?
The 2008 Audi S4 is ideal for enthusiasts who appreciate a blend of performance, luxury, and all-weather capability, and who are willing to accept higher running costs. It's definitely worth buying if you're looking for a V8-powered sports sedan or wagon on the used market and are prepared to address potential maintenance issues. A pre-purchase inspection by a qualified mechanic is crucial.
Given the age, buying used is the only option. Look for examples with a well-documented service history, ideally with evidence of timing chain maintenance. The Avant (wagon) version is particularly desirable for its added practicality. If you prioritize reliability and lower running costs, consider alternatives like the BMW 335i or Infiniti G37. Overall, the S4 provides a rewarding driving experience but requires careful ownership.
