Most electrical supply circuits in this vehicle are protected by fuses. High-current loads, such as headlights, radiator cooling fans, and the fuel pump, are connected via relays. Fuses and relays are housed in power distribution boxes located in the passenger compartment, engine compartment, and luggage compartment.
This article provides detailed fuse box diagrams and relay assignments for the second-generation Volkswagen Sharan (chassis code 7N; MQB platform) produced from 2010 through 2015 (gasoline and diesel models).
Engine Compartment
The engine compartment houses two power distribution boxes: the main fuse box and the high-power fuse box (indicated by the red markers in the photo above).
