Volkswagen Sharan – fuse and relay

The Volkswagen Sharan has been on the market from 1995 to the present in two generations. 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 restyled 2 times. Accordingly, there are also several box execution diagrams. In this material, we will show the location of all electronic control units, we will describe in detail the purpose of fuses and relays in the 1st generation Volkswagen Sharan. Separately, we note the cigarette lighter fuse.

The number of units, their design and the purpose of the elements may differ from the one presented and depend on the year of manufacture, the level of equipment and the country of delivery. We will present 2 of the most popular options: the 1st option is suitable mainly for models produced before 1998, and the 2nd after.

  • Do you have the 2012 VW Sharan diagrams?

  • i have sharan goal 2005 and i got diferent fuse boxs

  • Excellent information and useful. Thanks for the valuable information.

  • I have a 2016 seat Alhambra which is really a VW sharan. Do you have a diagram for this model?

  • Good day, I have sharon 2003 model. Whenever I am driving the door light and inner light blink. What can cause it

    • There could be a few potential causes for this issue. Here are some possibilities to consider:

      1) The blinking lights may indicate a problem with one of the door switches. These switches are responsible for detecting whether a door is open or closed. If a switch is faulty or becomes loose, it may send incorrect signals to the light circuit, causing the lights to blink.

      2) Another possibility is that there is a loose electrical connection somewhere in the lighting system. Vibrations from driving can cause loose connections to intermittently disconnect and reconnect, leading to blinking lights.

      3) It’s also possible that there is a problem with the wiring in the door or interior light circuit. Worn-out or damaged wiring can cause intermittent connections, resulting in blinking lights.

      4) And last one is malfunction in the vehicle’s electrical system could be the culprit. This could be due to a faulty relay, control module, or other electrical component that controls the lights. A diagnostic scan using specialized equipment may be necessary to identify the specific cause.
