The first generation of the Audi A4 was produced until 2001 with minor changes. At first, only the sedan version was available, the wagon version (Avant) appeared a year later. The car was based on the same platform as the fifth generation Volkswagen Passat. In dimensions, the A4 practically does not differ from the Audi 80. In this material, we will analyze in detail all the fuse diagrams of the first Audi A4 (1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001 year of manufacture, body B5).
Here you will find the locations and photos of the mounting blocks. Separately, we note the fuses responsible for the fuel pump and cigarette lighter.
