Volkswagen Caddy fuse and relay

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 designation of fuses and relays for the third generation Volkswagen Caddy (Caddy Typ 2K) produced in 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013 and 2014. We will also show you where the boxes are, their photos and diagrams. Separately, we 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 general designation for all units. We will present the most common ones for your reference.

  • The viper washer in vw caddy reg. 2017. Where in the fuse box is it?
    Regards Aki

  • My left back light unit is complete dead.No light working,not even the emergencylights.Where can I start.Caddy maxi crewbus 2018

  • This is a very good site to check your fuse locations.When you look at the above fuse locations dont forget that you will not have all the listed locations with fuses fitted in the coloured photo of the fuse box is upside down.My problem was that the heater fan in my Caddy was not working at all so I found the location from the numbered fuse drawing (it was number 33 showing as 40A heater switch and operating mode selection, air conditioning control unit).I now know that it has a 40amp fuse so now I know to look for a 40amp fuse on the coloured photo of the fuses above and also the location on my Caddy van fuse box.Next I checked the voltage over my 40 amp fuse in my van and all was well 12 volts.Then looking at the coloured photo of the fuse box above I counted the location from left to rite and the 40 amp fuse was located in the 9th fuse holder (40 amp).Now I looked at where my own 40amp fuse was located by again counting the number of slot locations and mine was in the 8th slot not the 9th as it should be.I moved my 40amp fuse to the 9th fuse holder and the heater works fine.

  • Can i turn off my cigarette socket when i turn off the ignition
