In autumn 2005, the fifth generation of the Mercedes-Benz S-Class, codenamed W221, was presented at the Frankfurt International Engine Show. The new S-Class is slightly wider, longer and taller than its predecessor, the W220, and also received three new powerful engines (up to 26% more power). In this material, we will analyze in detail the fuse circuits of the fifth generation Mercedes S-class (W221 / C216: S350, S450, S500, S65 AMG, S63) 2005, 2006, 2007, 2008, 2009 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 luggage compartment
Access is from the cabin. The armrest needs to be folded back. Then remove the trim, and the plastic cover.
