Known issues on the 2022 M550i xDrive. Turbocharged V8s put the heaviest demands on their cooling and lubrication systems, and the procedures here reflect that, from filling and bleeding coolant in sequence to keeping the turbocharger's oil supply and return correctly routed and sealed and torquing intake and exhaust fasteners to value so joints survive repeated heat cycles. Beyond the engine the manual supplies driveline procedures, brake specifications and suspension settings, and its wiring diagrams document the sedan's circuits for diagnostic work.
