In this article we will focus on the first generation BMW 1-series (E81/E82/E87/E88), produced from 2004 to 2013. Here you will find the BMW 1 series 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012 and 2013 (116i, 116d, 118i, 118d, 120i, 120d, 123d, 130i) fuse box images, information on the location of the fuse boxes in the vehicle and the assignment of the individual fuses (fuse layout) and relays.
Fuse box in the glove compartment
Fuse Box Location
Open the glove compartment, remove the damper (arrow 1) from the lower holder by applying forward pressure, disengage the glove compartment by pressing on both tabs (arrows 2) and fold it down.
After replacing a fuse, press the glove compartment upward until it engages and reattach the damper.
