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 designation of the purpose of fuses and relays in the Volkswagen T5 transporter with detailed boxes diagrams and their photographs. We will show the location of all control units and highlight the fuse responsible for the cigarette lighter for T5 and T6.
The number of elements in the boxes 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.

Hi, is this diagram OK for the 57 plate bnz engine (2.5 t5)?
Also, we noticed a lot of auxiliary heater fuses are missing or wrong type compared to the diagram… should we follow the diagram or trust the fuses (auxiliary heater seems to be playing up.)
Thanks in advance.
I can’t seem to see the ECM relay designated anywhere, is it described as something else on here.
Thanks
Hi did you find ecm relay as I have problems with mine 2015 transporter.?
Where is the glowplug relay situated on the kombi 1.9tdi T5?
58 plate T5..My wipers only work for a short time then may start again a little later but not always until vehicle is switched off for a while…already changed wiper motor, would this issue be relay if so where is it or could it be the stalk
Hi Kevin,
Did you ever find out what it was as I have the same issue! like you I have replaced the motor and have half pulled the dash out trying to find relays etc. Starting to loose the will to live.
Anything you found out would be greatly welcomed.
Thank Andy.
My indicator repeaters on both front wings don’t work. How are they wired and are they fuse indepentantly from the front and rear flashers which work ok.
I have a transporter T5 2009 model and has missed the connection flip for fuse no 30 – and need to take the fuse box out for getting it back in place. How do I demount the fuse box? Do I need to demount the whole dashboard? Thank you very much for your advice.
Hi,
Does a 2006 ( pre facelift ) have high capacity fuse box under battery ,,
Thanks
Sean
Evening guys, been looking at your diagrams, have a 2015 t5.1 with drivers side drl out, changed bulbs, no joy, no power at the bulb holder, and can’t see a listing for it, incase there is a dedicated fuse. Thank you
