Audi S8 3rd Generation Common Problems

The 3rd Generation Audi S8 (2012–2018) has its share of common problems. These issues can affect various parts of the vehicle, including the engine, suspension, and electronics. Being aware of these potential issues can help owners maintain their S8 and avoid costly repairs. Below are some of the most common problems associated with the S8, ranging from turbocharger failures to electrical malfunctions.

Keep in mind, that it is essential that all cars, even supercars, can have issues and it is crucial to perform a Pre-Purchase Inspection (PPI) from an authorized dealer or experienced independent mechanic to reveal all issues.

Turbocharger Failure: This can occur due to oil starvation or leaks, causing significant loss in engine power and potentially leading to engine damage. Repairs can be expensive due to the labor-intensive nature of replacing the turbochargers.

Carbon Build-Up: The direct injection system tends to accumulate carbon deposits on the intake valves, which may result in misfires, poor fuel economy, and rough idling. Regular carbon cleaning is recommended to prevent this issue.

Air Suspension Problems: The S8’s adaptive air suspension system is prone to leaks and compressor failures over time. When the air suspension fails, the car may drop to its lowest height, affecting ride quality and necessitating costly replacements of suspension components.

Electrical Malfunctions: The Audi S8 is equipped with numerous electronic systems, and failures can occur in the infotainment system, sensors, or modules. Common problems include malfunctioning backup cameras, navigation systems, or random electrical faults, which can be difficult to diagnose and repair.

Brake Wear: Due to the high performance of the S8, brake components such as pads and rotors tend to wear faster than in regular vehicles. Owners report frequent replacements, especially if the car is driven aggressively.

Recalls

2013 to 2017 Audi S8 vehicles

Engine and engine cooling (Recall no. 22V178000)

2013 to 2018 Audi S8 vehicles

Structure (Recall no. 20V397000)

The seal around the engine compartment may come loose and contact hot engine components. If the seal contacts hot engine components, there could be an increased risk of a fire.

2013 to 2016 Audi S8 vehicles

Fuel system, gasoline (Recall no. 19V057000)

The fuel supply line for the high pressure fuel pump may become porous and leak fuel. Leaking fuel, in the presence of an ignition source, increases the risk of fire.

2013 to 2015 Audi S8 vehicles

Fuel system, gasoline (Recall no. 18V430000)

The fuel supply line for the high pressure fuel pump may become porous over time, resulting in a fuel leak. A fuel leak in the presence of an ignition source can increase the risk of a fire.
