Known issues on the 2013 S8. Five recalls are on federal record for this model year. Two involve the high-pressure fuel pump's supply line, which can turn porous over time and leak fuel near an ignition source. A third covers the engine bay seal, which can work loose and contact hot engine components, raising the risk of fire. A fourth affects the standard sunroof glass panel, which on certain build dates may shatter, with falling glass able to injure occupants or distract the driver and increase the risk of a crash. The fifth covers the turbocharger's oil supply strainer, which can become blocked and starve the bearings, letting the turbine wheel contact its housing or the shaft break and stall the engine. Owners have filed 13 complaints for the year, and no technical service bulletins are logged.
From tracing a fuel-line leak to inspecting the turbo oil strainer or resealing the engine bay, it keeps you on the OEM procedure and the correct specification for your specific 2013 S8.
