Mercedes-Benz 210 represents the second generation of E-class passenger cars, which were produced in 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002 and 2003 with the W210 sedan and S210 station wagon bodies . During this time, the model has undergone restyling. In this material you will find information about the location of all electronic control units, a detailed description of the fuses and relays of the Mercedes 210 with block diagrams, photos, examples of execution and their locations. Let’s highlight the cigarette lighter fuse.
The location of the blocks and elements in them may differ from the one presented and depends on the year of manufacture and the level of electrical equipment of your car. Compare the information with your diagrams on the block cover.
