2014 BMW 550i xDrive Service and Repair Manual

This factory service and repair manual for the 2014 BMW 550i xDrive describes a sedan that hides its complexity well: four doors, one Base trim, and beneath the hood a turbocharged 4.4L V8 with double overhead camshafts running on gasoline, sending its output to all four wheels. Servicing an engine of that size in that space rewards preparation, and the manual supplies it, with the order of disassembly, the specifications each measurement is checked against, the values every fastener is tightened to, and the diagrams for the circuits that come off first.

Known issues on the 2014 550i xDrive. The V8 sections are the deepest part of this manual: timing chain and camshaft drive, cylinder heads and valve train, the turbocharging and charge-air hardware, lubrication and cooling, and the fuel supply from tank to injector, each with measured specifications and tightening values. Behind them come the automatic transmission, the transfer case and axles that make the car all-wheel drive, the braking and stability hardware, the steering and suspension, and the body circuits, all with diagnostic procedures written to isolate a fault before anything is replaced.
