2010 BMW 128i Service and Repair Manual

This factory service and repair manual for the 2010 BMW 128i is arranged by system, which suits a car offered with a single engine — the naturally aspirated 3.0L DOHC inline-six — in a single Base trim and two bodies, the two-door convertible and the two-door coupe. Engine work, driveline work and body electrical each sit in their own sections instead of being folded into one general chapter, so the convertible's roof mechanism and the coupe's fixed structure are addressed where they belong rather than scattered throughout.

• 3.0L inline-six — DOHC, naturally aspirated, gasoline
