Frequently reported problems for the 2005 Audi A8 revolve around a few key areas. The air suspension is a common source of trouble, with compressors and air struts failing, leading to expensive repairs. The MMI system is also known for glitches and malfunctions, impacting navigation, audio, and other controls. Electrical issues, in general, tend to surface as the car ages.
Oil leaks, particularly from the valve cover gaskets and timing chain tensioners, are also reported. Some owners have experienced transmission issues, though this is less common than suspension or electrical problems.
Recalls for the 2005 Audi A8 were relatively limited, primarily focusing on issues like potential fuel leaks or airbag malfunctions. It is crucial to check the vehicle's VIN for any outstanding recalls before purchasing.

How long will the 2005 Audi A8 last?
With proper maintenance, a 2005 Audi A8 can reach 200,000 miles or more. However, longevity heavily depends on maintenance habits. Neglecting regular servicing can accelerate wear and tear. The air suspension and electrical systems are typical weak points that require ongoing attention. The aluminum chassis is durable, resisting rust, but components like bushings and suspension arms will eventually need replacement. With diligent care, these cars can provide years of service, but expect higher maintenance costs compared to less complex vehicles.
What Technology & Safety Features are Included?
The 2005 Audi A8 boasted advanced technology for its time. Standard was the MMI (Multi Media Interface) system, controlling navigation, audio, and vehicle settings. A Bose sound system provided high-quality audio. Safety features included standard ABS, electronic stability control, and numerous airbags, including front, side, and curtain airbags.
Driver-assistance features included optional adaptive cruise control, which could maintain a set distance from the vehicle ahead. A navigation system was also available as an option. Some models also featured a solar sunroof on the A8L, which helped power the ventilation system.
Crash test ratings from the IIHS (Insurance Institute for Highway Safety) show the 2005 Audi A8 receiving generally good ratings for frontal offset and side impact tests. However, it's crucial to consult specific ratings for that model year on the IIHS website. Euro NCAP ratings, which may also be available, can provide additional insights into the vehicle's safety performance.

How Does the 2005 Audi A8 Compare to Other Sedan?
The 2005 Audi A8 competed with the BMW 7 Series, Mercedes-Benz S-Class, and Lexus LS 430. In terms of performance, the A8 offered comparable power and handling, especially with its quattro all-wheel drive. Features were also competitive, though the MMI system could be less intuitive than some rivals' infotainment systems.
Reliability is where the A8 often lagged behind, particularly compared to the Lexus LS 430, which is renowned for its dependability. The BMW 7 Series also had its share of electronic issues. The Mercedes S-Class offered a more luxurious ride but could be equally expensive to maintain.
Price-wise, used A8s are often more affordable than comparable examples of the S-Class or 7 Series, making them attractive to buyers on a budget. If reliability is a top priority, the Lexus LS 430 is a better alternative. For a balance of luxury and somewhat better reliability (though still not perfect), a later model Acura RL could also be considered.

Final Verdict: Is the 2005 Audi A8 a Good Sedan?
The 2005 Audi A8 is ideal for someone who appreciates luxury and performance but is willing to accept the potential for higher maintenance costs. It is worth buying *used* if you find a well-maintained example with a comprehensive service history and have a budget for potential repairs. The A8L offers more rear legroom. Avoid models with extensive deferred maintenance or signs of air suspension problems. It's a good choice for someone comfortable with DIY repairs or who has a trusted mechanic specializing in European cars. If reliability is paramount, alternative vehicles might be a better choice.
