Volkswagen Caravelle and Multivan models are technically and visually very similar. The primary distinction between them lies in their interior trim and cabin paneling. Both models are built on the same Volkswagen Transporter (T5) platform, representing its passenger variant. This publication provides detailed descriptions and diagrams for the fuse boxes and relay carriers in the Volkswagen Caravelle and Multivan (fifth generation; chassis codes 7H, 7J, 7E, 7F). Мodel years covered: 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, and 2015. Included below are control unit locations, schematic diagrams, photographs, and a video guide for locating fuse and relay panels, with special attention given to the cigarette lighter fuses across all variants.
Due to variations in vehicle equipment packages and wheelbase lengths, fuse assignments may differ. The most common configurations are illustrated below. If discrepancies arise, verify component assignments against the legend printed on the back of the fuse box cover, consult the owner’s manual, or contact an authorized Volkswagen dealer.
