2006 BMW M5 Service and Repair Manual

This factory service and repair manual for the 2006 BMW M5 documents something unusual in a four-door sedan: a 5.0L V10 with double overhead camshafts, naturally aspirated, on gasoline. Ten cylinders bring ten of everything that gets serviced individually, and the engine chapters lay out the procedures, clearances and torque sequences bank by bank. The rest of the manual covers the body as a whole, from transmission and driveline through brakes, suspension, steering and climate control to the restraints and the wiring that connects them.

Known issues on the 2006 M5. One recall stands on the federal record and it is an electrical heat problem. The insulated bulkhead connector for the positive battery cable may have been attached to the trunk floor incorrectly, letting the bolted joint loosen; resistance rises at the connection, the joint overheats, and a fire can start even with the car parked and switched off. Owner complaints run to 124, dominated by air bags at 55, then the electrical system at 19 and the power train at 13. Battery cable routing, restraint circuits and driveline diagnostics are covered here.
