Fuses and relays Volkswagen Caravelle / Multivan (T5; 2002-2015)

Volkswagen Caravelle and Multivan are very similar both technically and externally. Their main difference between themselves is the interior trim and panels. Both of these models are released on the same base with the wv transporter and represent its passenger version. In this publication you will find a description of the fuse boxes and relays of the Volkswagen Karavella (Multiven) T5. Years of manufacture of the fifth generation (T5): 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015. We will also show the location of all control units, a video example of finding exactly the fuse and relay blocks, as well as their photos and diagrams. We will pay special attention to the fuses responsible for the cigarette lighter for both generations.

Due to the wide variety of equipment options and the length of the body base, there is no one general description of the purpose of all elements. We will show the most common ones. In case of difficulty, check the designation with yours, on the back of the protective cover or instructions, or contact your nearest dealer.
