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, 2011,20. 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 the most common ones for your reference.
General arrangement of blocks
- Fuses in the fuse block (A -SA-), additional relay block under the switching 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
Blocks under the hood
Fuse and relay block
Located next to the battery. Consists of high-power fuses connected to the battery and a compartment with fuses and relays.
