Volkswagen Caddy is a light commercial vehicle, produced in two body styles: van and minivan, in 4 generations since 1980. In our material you will find a description of fuses and relays for the third generation Volkswagen Caddy (Caddy Typ 2K), which was produced in 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013 and 2014. We will also show where the blocks are located, their photos and diagrams. We will separately highlight the fuse responsible for the cigarette lighter.
Due to the fact that the Volkswagen Caddy was produced with different body variants, trim levels and electrical equipment, and also underwent a facelift in 2010, there is no single general description for all units. We will present for your reference the most common ones.
General arrangement of blocks Volkswagen Caddy
- Fuse links in the fuse block (A -SA-), additional relay block under the switch block
- Fuses and relays in the switchboard (B -SB-)
- Fuse and relay block under the front panel on the left (C -SC-)
- Relay in the footwell
