The VW Passat B6 represents the sixth generation of the Passat model range. Produced from 2005 through 2010 in both sedan and station wagon (Variant) body styles, it was offered with a variety of gasoline and diesel engines. The 4-door coupé based on the B6 platform was marketed as a standalone model, the Passat CC, and was manufactured from 2008 to 2012. This article provides detailed descriptions, component diagrams, and location photographs for the fuse boxes and relay panels on the Volkswagen Passat B6 and Passat CC (chassis codes 3C / 357; PQ35 / PQ46 platforms). In addition, the fuses responsible for the cigarette lighter and auxiliary 12 V power outlets are specifically highlighted.
