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.
Here you will find the locations and photos of the fuse blocks. Separately, we note the elements responsible for the cigarette lighter and fuel pump.
In the luggage compartment
The luggage compartment mounting block is located behind the trim on the left.
Photo is an example.
