Volkswagen Passat B6 introduces the 6th generation of the trade wind range. Produced in 2005, 2006, 2007, 2008, 2009 and 2010 with both gasoline and diesel engines with sedan and station wagon bodies. The 4-door coupe based on the Passat B6 represents a separate model called the Passat CC and was produced from 2008 to 2015. In this article, we will present a designation of the Volkswagen Passat B6 (CC) fuse boxes and relays with diagrams and photographs. Separately, we highlight the fuse responsible for the cigarette lighter.
Please note that the number of boxes and their versions may differ from this material and depend on the year of manufacture and the level of electrical equipment of your car.
