Volkswagen Sharan has been supplied to the markets from 1995 to the present in two generations. The 1st generation was produced in 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008 and 2009. During this time, the car was restyling twice. Accordingly, the block execution schemes, as well as several. In this material, we will show the location of all electronic control units, describe in detail the purpose of fuses and relays in the Volkswagen Sharan 1st generation. Separately, we will note the cigarette lighter fuse.
The number of blocks, their design and purpose of the elements may differ from the one presented and depends on the year of manufacture, equipment level and country of delivery. We will present the two most popular options: the first option is suitable mainly for models manufactured before 1998, and the second after.
