Known issues on the 2016 S8. Three recalls are on federal record for this model year. The first covers the fuel supply line for the high pressure fuel pump, which can become porous and leak fuel, and leaking fuel in the presence of an ignition source increases the risk of fire. The second covers the seal around the engine compartment, which may come loose and contact hot engine components, increasing the risk of a fire. The third covers the turbocharger oil supply strainer, which can become blocked and cause wear to the bearings due to lack of lubrication; worn bearings can cause the turbine wheel to contact the turbocharger housing or cause the shaft to break, causing an engine stall and increasing the risk of a crash. Owners have filed 6 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

From a fuel line inspection to a hood-seal check or a full turbocharger service, it keeps you on the OEM procedure and the correct specification for your specific 2016 S8.
