The fifth-generation BMW 3 Series was launched in March 2005. It shares its platform with the BMW X3 and BMW 1 Series. The vehicle was available in Sedan (E90), Wagon/Touring (E91), Coupé (E92), and Convertible (E93) body styles. In this article, we provide a detailed overview of the fuse box diagrams for the BMW E90 / E91 3 Series (5th Gen; 316d, 316i, 318d, 318i, 320si, 320d, 323i, 325i, 328i, 330d, 330i, 335d, 335i, M3) for model years 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, and 2013.
Below you will find the locations and diagrams for the power distribution boxes. Fuses responsible for the “Cigarette lighter” and “Fuel pump” are highlighted in bold.
In the engine compartment
Depending on vehicle equipment, several power distribution units may be located in the engine bay. To access them, loosen the retaining fasteners and remove the protective cowl trim panel.
