What Problems Does the 2008 Audi S8 Have?
Frequently reported problems with the 2008 Audi S8 often center around the complexity of the vehicle's systems. The 5.2L V10 engine, while powerful, can suffer from oil consumption issues and timing chain concerns. The adaptive air suspension is another common point of failure, leading to expensive repairs. Electrical issues, including problems with the Multi Media Interface (MMI) and various sensors, are also not uncommon.
Recalls for the 2008 Audi S8, if any, would be related to safety concerns and should be checked on the NHTSA website using the VIN. Long-term reliability is a concern due to the age of the vehicle and the complexity of its components. Deferred maintenance can exacerbate these issues, leading to costly repairs. Specifically, issues with the direct injection system (carbon buildup) can impact performance and fuel economy. Regular servicing and careful monitoring of engine oil levels are crucial to mitigating potential problems. Furthermore, diagnostic scans should be performed regularly to identify and address potential issues before they escalate into major repairs.

How long will the 2008 Audi S8 last?
Given its age, a 2008 Audi S8 will likely have accumulated significant mileage. Expect to find examples ranging from 100,000 to 200,000 miles or more. Long-term durability depends heavily on maintenance habits. Well-maintained examples can still provide reliable service, but neglect can lead to a cascade of problems. Weaknesses over time include the aforementioned air suspension failures, engine issues (oil consumption, timing chain), and electronic gremlins. Proper fluid changes (engine oil, transmission, differentials) and addressing issues promptly are key to extending the vehicle's lifespan. Ignoring these aspects will dramatically shorten its usable life.

How Does the 2008 Audi S8 Compare to Other Sedan?
The 2008 Audi S8 competed with other high-performance luxury sedans like the BMW 7 Series (specifically the 750i or 760Li), the Mercedes-Benz S-Class (S550 or S600), and the Jaguar XJR.
Performance: The S8's V10 offered comparable performance to the V8 and V12 options from BMW and Mercedes. The Jaguar XJR offered similar levels of power.
Features: The S8 was well-equipped, but rivals offered similar levels of luxury and technology.
Reliability: The S8 is generally considered less reliable than the BMW 7 Series or Mercedes-Benz S-Class, particularly concerning the engine and air suspension. The Jaguar XJR's reliability record is also mixed.
Price: Used S8s are often priced competitively compared to similar-year rivals, reflecting the higher maintenance costs.
Alternatives: If reliability is a primary concern, a well-maintained BMW 750i or Mercedes-Benz S550 might be a better choice. The Jaguar XJR offers a similar blend of performance and luxury but also comes with potential reliability concerns. For a blend of performance and newer tech, a newer (but possibly smaller) Audi S6 might be considered if budget allows.

The 2008 Audi S8 is ideal for enthusiasts who appreciate high-performance luxury sedans and are willing to accept the associated maintenance costs. It's worth buying *used* if you find a well-maintained example with a thorough service history and have the budget for potential repairs. Avoid examples with deferred maintenance or signs of neglect. Focus on finding an S8 with documented preventative maintenance on the engine and air suspension. It's not recommended for those seeking an economical or low-maintenance vehicle. A pre-purchase inspection by a qualified Audi mechanic is essential before making a purchase. Consider it a passion purchase, not a practical one.
