The Mercedes-Benz W213 is the fifth generation of the E-Class, which was produced from 2016 to 2024. The car replaced the W212 model and was presented in four body types: sedan (W213), station wagon (S213), coupe (C238) and convertible (A238). In 2020, the model underwent restyling, receiving an updated design and the latest multimedia system.
Engines for the W213 were offered in a very wide range:
Petrol: from inline 2.0-liter (e.g. 184 hp in the E200) to the biturbo 4.0-liter V8 in the Mercedes-AMG E63 versions (up to 612 hp).
Diesel: modern turbodiesels such as the inline 2.0-liter OM 654 (150-194 hp) and the 3.0-liter V6.
Hybrid: included plug-in hybrids (e.g. E 350 e) and micro-hybrid systems with a 48-volt network (EQ Boost).
Key features of the W213 generation: Advanced driver assistance systems and autonomous control elements. Two widescreen displays of 12.3 inches in the cabin. Modular rear-wheel drive platform MRA and 9-speed automatic transmission 9G-Tronic.
This article will focus on fuses and relays on the car. It should be said right away that the mounting blocks themselves are unified with the Mercedes w205 model (Mercedes). That is, they visually meet one in the other, but as for the fuses in them and their purposes, there are differences. But for reference, you can also see the w205 model (Mercedes).
