Fuses and relays Mercedes M-Class (W164; 2005 - 2011)

The Mercedes-Benz M-Class in the back of the W164 was first presented at the Detroit Auto Show in early 2005. He shared a technical base with the R-Class (W251) and the Mercedes-Benz GL-Class. The frame structure that was used in the previous model was replaced by a monocoque body, which led to improved passive safety, but reduced the vehicle's off-road capabilities. In this material, we will analyze in detail the fuse circuits of the second generation Mercedes M-class (W164: ML350, ML500, ML550, ML620): 2005, 2006, 2007, 2008, 2009, 2010, 2011 release.
