Fuses and relays VW Transporter (T5; 2003-2014)

Volkswagen Transporter T5  belongs to the class of cargo and passenger vehicles. It was produced with minivan, van and pickup bodies with both diesel and gasoline engines. Produced in 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013 and 2014. From 2015 to the present, the sixth generation (T6 is in production. In our material you will find a description of the purpose of fuses and relays in the Volkswagen T5 transporter with detailed block diagrams and their photographs. We will show the location of all control units and highlight the fuse responsible for the cigarette lighter.

The number of elements in the blocks may differ from the one presented and depends on the year of manufacture (the car was restyled in 2010) and the level of its electrical equipment.
