Volkswagen Caravelle and Multivan are very similar both technically and externally. The main difference between them 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 designation of the Volkswagen Caravelle (Multivan) fuse and relay boxes. Years of the fifth generation (T5): 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013 and 2014. Since 2015, the sixth generation (T6). We will also show the location of all control units, a video example of finding exactly the fuse and relay boxes, 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.

This box contains fuses responsible for the cigarette lighter (number SF11) and additional sockets.
Fuses Caravella T6
In the sixth generation, the main fuse box is located under the glove compartment.
Photo an example of a T6 fuse box
Here is the fuse responsible for the cigarette lighter (circled in red).
As you can see, the arrangement of the boxes in the Volkswagen Caravelle (Multivan) T5 and T6 is similar. However, their diagram are different.
