Known issues on the 2022 840i xDrive. Heat and pressure define the service life of a forced-induction six, and the systems that manage both are specified in detail for the 2022 840i xDrive: coolant routing, thermostat and pump behavior, radiator and charge-air cooling service, oil supply and capacity, and the boost-control checks that show whether a pressure target is being met. Around them sit the timing and valvetrain figures, the fuel and ignition tests, the chassis dimensions, and the body and roof procedures, each with the wiring diagram for its circuits.
