Known issues on the 2008 650i. The chassis is where much of the labor lands, and the coverage is specific: suspension arm and subframe torque values, wheel bearing and hub procedures, alignment specifications, brake service and hydraulic bleeding, and steering component overhaul. Engine work is documented to the same level, from timing drive and valve train service to fuel and ignition diagnostics on the V8, and wiring diagrams carry the body, lighting and comfort circuits, including the convertible's roof controls. Diagnostic routines are organized by system so a symptom leads to a measurement.
