Mercedes ML W164 (GL X164) fuse and relay

Mercedes ML W164 is the second generation of Mercedes-Benz M-class SUVs which were produced in 2005, 2006, 2007, 2008, 2009, 2010, 2011 and 2012 with petrol and diesel engines ML 280 CDI, ML 300, ML 320, ML 350, ML 420, ML 450, ML 500, ML 550, ML 620, ML 63 AMG. During this time, the model has been restyled. This information will also be useful to owners of the Mercedes GL X164 GL 320, GL 350, GL 420, GL 450 and GL 500 4MATIC, since these models have similar electrical circuits. In this article, we will show the locations of electronic control units, a description of the fuses and relays of the Mercedes 164 with box diagrams, photo examples of their execution and locations. Select the fuse responsible for the cigarette lighter.
