The 2005 Audi S4 is a performance-oriented variant of the Audi A4, known for its powerful V8 engine and Quattro all-wheel drive. It was available as a sedan, Avant (wagon), and Cabriolet. The B6 generation S4, including the 2005 model year, was produced from 2003-2005. Key trims are essentially defined by body style and options packages. When new, pricing ranged from around $45,000. It's popular for its blend of luxury, performance, and all-weather capability.
The Good
The 2005 Audi S4 offers strong performance from its V8 engine and secure handling thanks to Quattro. It provides a comfortable and luxurious interior. The exterior design is understated yet sporty. A practical buyer appreciates the all-weather capability and relative reliability (with proper maintenance). Emotionally, the V8 sound and performance are appealing.
The Bad
Potential weaknesses of the 2005 Audi S4 include higher running costs due to the V8 engine. The timing chain tensioners are a known issue and can be very expensive to repair. Suspension components and electrical systems can also be prone to problems with age. Fuel economy isn't great compared to smaller-engined rivals.

What Problems Does the 2005 Audi S4 Have?
The 2005 Audi S4, and the B6 generation in general, has several frequently reported problems. The most significant is related to the timing chain tensioners. These can fail, leading to catastrophic engine damage. Repair is very expensive, often exceeding the value of the car. Early preventative maintenance is crucial.
Another common issue is with the mass airflow sensor (MAF), which can cause poor engine performance and fuel economy. Suspension components, such as control arms, can wear out, leading to alignment problems and handling issues.
Electrical gremlins are also reported, including issues with the instrument cluster, power windows, and central locking system. The automatic transmission can experience problems, particularly with valve body wear. The clutch in manual transmission cars can wear prematurely, especially with aggressive driving.
Check engine lights are common, often related to emissions control systems or the aforementioned MAF sensor. Recalls for the 2005 S4 were relatively limited, but it's important to check the NHTSA website for any outstanding recalls related to safety or emissions. Long-term reliability hinges on diligent maintenance, addressing issues promptly, and being prepared for potentially expensive repairs.

Long-term reliability hinges on diligent maintenance, addressing issues promptly, and being prepared for potentially expensive repairs.
How long will the 2005 Audi S4 last?
Given its age, a 2005 Audi S4 is likely to have accumulated well over 150,000 miles, possibly exceeding 200,000 miles, depending on usage. With meticulous maintenance, many owners have reached or surpassed these figures. However, long-term durability is highly dependent on consistent preventative care. As these cars age, expect increased wear and tear on suspension, bushings, and rubber components. Oil leaks are common. The timing chain issue remains a significant long-term concern. Neglecting maintenance will significantly shorten the lifespan and increase repair costs. Cars with complete service records and evidence of proactive maintenance will generally last longer.
What Technology & Safety Features are Included?
The 2005 Audi S4 offered a reasonable level of technology for its time. Standard features included a premium sound system with a CD player, dual-zone automatic climate control, and power-adjustable and heated front seats. Optional tech included a navigation system (which, by modern standards, is quite dated), a Bose premium audio system upgrade, and rear parking sensors.
Driver-assistance features were limited compared to modern cars. There were no lane departure warnings, blind-spot monitoring, or adaptive cruise control available. Safety features included anti-lock brakes (ABS), electronic stability program (ESP), and front and side airbags. Side curtain airbags were also available.
The NHTSA (National Highway Traffic Safety Administration) and IIHS (Insurance Institute for Highway Safety) crash test ratings for the 2005 Audi A4 (which the S4 is based on) are generally good for its class and era. However, it's important to remember that crash-test standards have evolved significantly since 2005, and newer cars offer significantly improved protection. The NHTSA gave the 2005 A4 four stars for frontal crash protection (driver and passenger) and five stars for side crash protection. Always consult official NHTSA and IIHS websites for the most accurate information.
Keep in mind that technology and safety features were not as advanced as today’s standards.

2005 Audi S4 Prices and Market Value
When new, the 2005 Audi S4 had an MSRP starting around $45,000, depending on the body style and options. Current used market prices vary widely based on mileage, condition, and location. Expect to find examples ranging from $5,000 to $15,000, with cleaner, lower-mileage examples commanding a premium. Depreciation has been significant, as is typical for luxury performance cars. Factors affecting resale value include: documented maintenance history, overall condition (especially the interior and paint), the presence of desirable options, and the absence of major mechanical issues (particularly the timing chain). The Avant (wagon) version often holds its value slightly better due to its relative rarity.
2005 Audi S4 Cost of Ownership
The 2005 Audi S4 is not an economical car to own. Insurance costs will be higher than average due to its performance classification. Fuel economy is poor, requiring premium gasoline. Maintenance and repair costs can be substantial, particularly if the timing chain tensioners require replacement. Parts can be expensive and labor rates are typically higher for European vehicles. Long-term ownership requires a dedicated budget for potential repairs and preventative maintenance to avoid major breakdowns. Overall, expect higher than average operating costs.

How Does the 2005 Audi S4 Compare to Other Convertible?
The 2005 Audi S4 competed with vehicles like the BMW 330i/335i, Mercedes-Benz C32/C55 AMG, and Acura TL Type-S. In terms of performance, the S4's V8 offered competitive power and the Quattro all-wheel drive provided superior traction, especially in adverse weather. The BMW offered arguably sharper handling, while the Mercedes delivered more raw power in the AMG variants. Feature-wise, the S4 was generally well-equipped, but lacked some of the advanced technology offered by competitors like Acura.
Reliability is where the S4 falters compared to some rivals. The BMW and Acura models are generally considered more reliable and less prone to expensive mechanical issues. The Mercedes-Benz AMG models can also be costly to maintain, but often have a reputation for durability.
Price-wise, used S4s can be attractive due to their depreciation. However, potential repair costs should be factored in. Alternatives to consider include the BMW 335i (for a similar performance feel with potentially better reliability), the Acura TL Type-S (for a more reliable and affordable option with good performance), or a newer, less expensive sports sedan like a Subaru WRX (for more modern features and similar performance). A well-maintained Audi S4 of the same era could be a suitable alternative if the timing chain tensioner issue has already been addressed.

Final Verdict: Is the 2005 Audi S4 a Good Convertible?
The 2005 Audi S4 is ideal for enthusiasts who appreciate a V8 engine, all-wheel drive, and a blend of luxury and performance. It's worth buying *if* you're aware of its potential maintenance costs and are prepared to address them proactively. It is *not* recommended for budget-conscious buyers seeking a reliable and economical daily driver.
Buying a used example is the only option, of course. Look for cars with extensive service records, particularly those that document timing chain tensioner maintenance or replacement. A pre-purchase inspection by a qualified Audi mechanic is essential. The Avant (wagon) is a desirable choice for those needing extra cargo space. If you find a well-maintained example at a reasonable price and are willing to invest in its upkeep, the 2005 Audi S4 can be a rewarding ownership experience. Otherwise, consider other alternatives.
