Fuses and relays Volkswagen Caddy (2K), 2003 - 2015

Volkswagen Caddy is a light commercial vehicle produced with two body options: a van and a minivan, in 4 generations since 1980. In our material you will find a description of fuses and relays for the third generation Caddy (Typ 2K) produced in 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013 and 2014, 2015. We will also show you where the blocks are, their photos and diagrams. Separately, we will highlight the fuse responsible for the cigarette lighter.

Due to the fact that the Volkswagen Caddy was produced with various body options, equipment levels and electrical equipment, and also underwent a facelift in 2010, there is no one common description for all units. We will present the most common ones for review.

General arrangement of fuse blocks


1 - Fuse-links in the fuse holder (A -SA-), additional relay box under the electrical box
2 - Fuses and relays in the switching unit (B -SB-)
3 - Fuse and relay box under dash panel, left (C -SC-)
4 - Footwell relay

In engine compartment

Fuse and relay box


Located next to the battery. Consists of high power fuse-links connected to the battery and a compartment with fuses and relays.
