The first generation Mercedes Benz ML-Class (W163) was produced from 1997 to 2005. This mid-size frame SUV was offered in five or seven-seater variants. It became the first luxury SUV to be fitted with an electronic stability control system. In this material, we will analyze in detail the first generation Mercedes M-class fuse circuits (W163 - ML230, ML320, ML370, ML430, ML500): 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005 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.
