Known issues on the 2019 M4. What the manual gives on this car is the detail a forced-induction six demands: charge air and cooling procedures, fuel delivery specifications, and the torque sequences for the cylinder head, manifolds and turbocharger mountings. From there it moves outward, through transmission removal, driveshaft and differential work, and brake and suspension specifications with the figures to check them against. The wiring diagrams carry the engine management, chassis control and body circuits with their connectors and ground points named.
