Known issues on the 2015 S8. Four recalls are on federal record for this model year. Two concern the fuel system: the high-pressure fuel pump supply line can turn porous over time and leak fuel, raising the risk of fire. A third covers the engine compartment, where a loose seal can contact hot engine components, also raising the risk of fire. The fourth covers the turbocharger, where a blocked oil supply strainer can starve the bearings, letting the turbine wheel contact its housing or the shaft break, causing an engine stall and increasing the risk of a crash. Owners have filed 6 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind each of those systems are here.
Whether you're inspecting the fuel supply line, checking the turbocharger oil strainer, or working through a routine service interval, it keeps you on the OEM procedure and the correct specification for your specific 2015 S8.
