Known issues on the 2018 S8. One recall is on federal record for this model year, covering the seal around the engine compartment: on affected 2013-2018 S8 and A8 vehicles, the seal can come loose and contact hot engine components, raising the risk of a fire. The factory diagnostic and repair procedures behind that system are here.
From inspecting the engine bay seal to routine service on the turbocharged V8, it keeps you on the OEM procedure and the correct specification for your specific 2018 S8.
