The 2004 Audi S4 marked a significant shift, boasting a powerful V8 engine after years of turbo sixes. Available as a sedan, Avant (wagon), and Cabriolet (convertible), it falls within the B6 generation (2003-2005). Key trims centered around the body style. Pricing ranged from around $45,000 new. Its combination of refined luxury, sporty performance, and all-wheel drive, made it a desirable enthusiast's car. The V8 sound and capability set it apart.
The Good
The 2004 Audi S4 offers exhilarating V8 performance and quattro all-wheel-drive grip, appealing to emotional buyers. Practicality stems from its comfortable interior, available wagon body style, and solid build quality. While not the most fuel-efficient, its reliability (with proper maintenance) and potential for long-term value make it a compelling choice.
The Bad
The 2004 Audi S4's weaknesses include potential timing chain issues, especially if maintenance was neglected. High oil consumption is also a known concern. Suspension components and the notoriously weak stock clutch (if manual) can require replacement. Electronics can be finicky. Thorough pre-purchase inspection is crucial.

What Problems Does the 2004 Audi S4 Have?
Frequently reported problems for the 2004 Audi S4 center around its 4.2L V8 engine. The most significant concern is timing chain wear and eventual failure. This is a costly repair, as it requires extensive engine disassembly. High oil consumption is another common issue, sometimes attributed to worn valve stem seals or piston rings.
Suspension components, particularly control arm bushings, are prone to wear, leading to clunking noises and reduced handling precision. The clutch in manual transmission models is often cited as being weak and prone to slippage, especially with spirited driving.
Electrical issues, such as failing sensors or malfunctioning displays, can also occur. The convertible top mechanism in the Cabriolet can sometimes experience problems.
While there weren't any major recalls specific to the 2004 model year that drastically affect reliability, checking for any outstanding recalls related to safety or emissions is always recommended. Long-term reliability depends heavily on maintenance history. Neglecting oil changes or ignoring warning signs can exacerbate these problems, leading to significant repair bills. Cars with comprehensive service records are generally a safer bet.

Cars with comprehensive service records are generally a safer bet.
How long will the 2004 Audi S4 last?
Given its age, a 2004 Audi S4 typically has well over 150,000 miles. With diligent maintenance, including regular oil changes (using the correct synthetic oil) and addressing issues promptly, it can reach 200,000 miles or more. However, long-term durability hinges on the aforementioned timing chain issue. This is a major factor determining longevity. The car's aluminum suspension components can also be a long-term weakness, requiring periodic replacement. Proper climate control system care is necessary to maintain function over time.
What Technology & Safety Features are Included?
The 2004 Audi S4, while not cutting-edge by modern standards, offered a solid array of tech and safety features for its time. Built-in tech included a premium sound system (often Bose as an option), dual-zone automatic climate control, and available navigation system (using a CD-based system). Entertainment centered around the radio and CD player; auxiliary inputs were uncommon at this time.
Driver-assistance features were limited compared to today's cars. Rear parking sensors were an optional extra. Safety features included standard anti-lock brakes (ABS), electronic stability control (ESP), and a suite of airbags (front, side, and curtain).
Optional features could add heated front seats, auto-dimming mirrors, and xenon headlights.
Crash-test ratings from the NHTSA (National Highway Traffic Safety Administration) and IIHS (Insurance Institute for Highway Safety) should be researched specifically for the 2004 model year using their respective websites, as ratings can vary. Generally, the S4 received good marks for occupant protection in frontal and side impacts, but a thorough investigation of these sources is recommended for precise details.

How Does the 2004 Audi S4 Compare to Other Passenger Sedan?
The 2004 Audi S4 competed with cars like the BMW 330i (E46), Mercedes-Benz C32 AMG (later C55), and Infiniti G35. In terms of performance, the S4 offered a strong V8, but the C32 AMG delivered more raw power. The BMW 330i provided sharper handling, while the G35 offered a more modern interior and comparable performance at a lower price point. Features were relatively similar across the segment, with each offering luxury appointments and available options.
Reliability is where the S4 lags behind some competitors. The BMW 330i is generally considered more reliable, while the Mercedes-Benz C32 AMG can also be problematic. The Infiniti G35 often proves to be a more dependable choice.
In terms of price, a used S4 might be appealing, but factor in potentially higher maintenance costs.
Alternatives to consider include a well-maintained BMW 330i ZHP for a balanced blend of performance and reliability, or an Infiniti G35 for a more affordable and potentially more reliable option. If raw power is the priority, the C32 AMG might be tempting, but proceed with caution due to potential maintenance costs. A Lexus IS300 could offer better reliability, albeit with less performance.

Final Verdict: Is the 2004 Audi S4 a Good Passenger Sedan?
The 2004 Audi S4 is ideal for driving enthusiasts who appreciate a blend of V8 power, all-wheel drive, and German luxury. It's worth buying *if* you're prepared for potentially high maintenance costs and prioritize a unique driving experience over outright reliability. Buying used is the only option now, and a pre-purchase inspection by a qualified Audi mechanic is essential. Focus on examples with comprehensive service records, especially those documenting timing chain maintenance. The Avant (wagon) is a more practical choice, if you can find one. If you're budget-conscious or prioritize reliability above all else, consider alternative options.
