Known issues on the 2018 A8 Quattro. Two recalls are on federal record for this model year. The first covers the seal around the engine compartment, which can come loose and contact hot engine components, increasing the risk of a fire. The second covers the left and right fuel rails, which may leak fuel and, in the presence of an ignition source, increase the risk of a fire. The factory diagnostic and repair procedures behind each of those systems are here.
From an engine bay seal inspection to a fuel rail check or a routine service interval, it keeps you on the OEM procedure and the correct specification for your specific 2018 A8 Quattro.
