What Problems Does the 2004 Audi A8 Have?
Frequently reported problems for the 2004 Audi A8 often revolve around its complex systems. The air suspension is a common source of trouble, with compressors, air struts, and control modules prone to failure, leading to expensive repairs. Electrical issues, such as problems with the central convenience system, malfunctioning sensors, and issues with the infotainment system, are also frequently reported.
The timing belt is a critical maintenance item on the 4.2L V8. Failure to replace it at the recommended interval (typically around 75,000-90,000 miles) can result in catastrophic engine damage.
Recalls for the 2004 Audi A8, while not always frequent, should be checked via the NHTSA website using the vehicle's VIN. Common areas for recalls across similar Audi models of this era include issues related to airbags, fuel systems, or electrical components. Long-term reliability is a concern due to the age and complexity of the vehicle. Parts can be costly and harder to find, and deferred maintenance by previous owners can lead to a cascade of problems. Specifically, look for documentation of timing belt replacement, air suspension maintenance, and transmission servicing.

Specifically, look for documentation of timing belt replacement, air suspension maintenance, and transmission servicing.
How long will the 2004 Audi A8 last?
Given its age, a 2004 Audi A8 is likely to have accumulated significant mileage. Well-maintained examples could reach 200,000 miles or more. However, longevity heavily depends on consistent maintenance, especially addressing the air suspension, timing belt, and electrical systems. Poor maintenance habits drastically shorten lifespan. The aluminum chassis is durable, but components like bushings, hoses, and seals will degrade over time, requiring replacement. Expect higher maintenance costs as the car ages, irrespective of mileage, because age affects rubber and plastic components.
What Technology & Safety Features are Included?
The 2004 Audi A8 featured advanced technology for its time. Standard features included a Bose sound system, a navigation system (often with a small screen), dual-zone automatic climate control, and xenon headlights.
Entertainment options included a CD changer, and potentially an early form of satellite radio. Driver-assistance features were limited compared to modern cars, but included parking sensors. Safety features consisted of anti-lock brakes (ABS), electronic stability program (ESP), traction control, and a comprehensive airbag system (front, side, and curtain airbags).
Optional features could include upgraded leather upholstery, massaging front and rear seats, adaptive cruise control (ACC) – though early versions were less sophisticated than today's systems – and a rear-seat entertainment system. Euro NCAP crash-test ratings (the European equivalent of NHTSA) were generally high for occupant protection. U.S. NHTSA ratings, if available, can be checked online. The Audi A8 lacked modern conveniences like smartphone integration (Apple CarPlay/Android Auto) and advanced driver-assistance systems (ADAS) such as lane departure warning or automatic emergency braking.

On the used market, prices can range from $3,000 to $10,000 or more, depending on condition, mileage, and maintenance history.

How Does the 2004 Audi A8 Compare to Other Sedan?
The 2004 Audi A8 competed with the BMW 7 Series, Mercedes-Benz S-Class, and Lexus LS 430. In terms of performance, the A8's quattro all-wheel drive gave it an advantage in inclement weather compared to rear-wheel-drive rivals. Features were comparable across the class, with each offering luxury amenities. However, the A8's reliability trailed behind the Lexus LS 430, known for its exceptional dependability. The BMW 7 Series offered a sportier driving experience, while the S-Class emphasized luxury and comfort.
In terms of price on the used market, the A8 might be slightly more affordable than some of its rivals, but its higher potential maintenance costs offset any initial savings. A potentially better alternative, for those prioritizing reliability, is the Lexus LS 430. For those wanting similar features but potentially lower running costs and willing to sacrifice some luxury, a well-maintained Acura RL could be considered. The BMW 7 Series can offer a similar level of driving pleasure, but shares comparable reliability concerns.

Final Verdict: Is the 2004 Audi A8 a Good Sedan?
The 2004 Audi A8 is ideal for enthusiasts who appreciate its design, all-wheel-drive performance, and luxurious features, and are prepared for potentially high maintenance costs. It is worth buying only under specific conditions: a thorough pre-purchase inspection by a qualified mechanic is crucial, along with a complete maintenance history, especially regarding the timing belt and air suspension. Opting for a well-maintained example with documented service records is essential. Given its age, buying used is the only option. The A8 L offers more rear legroom. However, it is not recommended for those seeking a reliable and economical daily driver.
