The Mercedes-Benz E-Class W212 generation is represented by a wide range of bodies. The sedan (W212) was the first to go on sale in the spring of 2009. In May 2009, the E-Class coupe under the C207 index came to replace the CLK-Class coupe and convertible, and a little later, towards the end of 2009, sales of the S212 station wagon began. As a finishing touch, another member of the generation, the luxury A207 convertible, went on sale in March 2010. In this material, we will analyze in detail the fuse circuits of the fourth generation Mercedes-Benz E-class (body W212: E200, E250, E300, E350, E500): 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016 model year.
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 engine compartment
The main fuse box is located near the windshield on the left side. An additional block is located near the right pillar.
