Known issues on the 2020 M550i xDrive. Most of this manual's working life is spent supplying figures: torque values for engine and chassis hardware, clearances and specifications for the V8, brake dimensions, and the alignment settings a suspension repair has to finish on. The rest of it is layout, in the form of wiring diagrams showing how the sedan's circuits are actually routed and diagnostic sequences that begin at the symptom and work back through the components and connections capable of producing it, rather than starting with the part most often replaced.
