Known issues on the 2015 A8 Quattro. Five recalls are on federal record for this model year. Three concern fuel system leaks: a porous high-pressure fuel pump supply line, and separately leaking left and right fuel rails, both of which can leak fuel near an ignition source and raise the risk of fire. A fourth covers a hood seal that can come loose and contact hot engine components, again increasing fire risk. The fifth covers the turbocharger oil supply strainer, which can become blocked and starve the turbo bearings, allowing the turbine to contact its housing or the shaft to break, causing an engine stall and increasing the risk of a crash. Owners have filed 31 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind each of those systems are here.
From tracing a fuel-line leak to inspecting the turbocharger oil strainer or the engine bay hood seal, it keeps you on the OEM procedure and the correct specification for your specific 2015 A8 Quattro.
