The 4th generation Volkswagen Caddy was produced from 2015 to 2020. However, this light commercial vehicle (LCV) is essentially a deep facelift of the 3rd-generation model. In this guide, we provide a detailed breakdown of the fuse box diagrams for the VW Caddy IV (fourth generation; chassis codes SA, SE; MQB A5 / PQ35 platform) for the 2015, 2016, 2017, 2018, 2019, and 2020 model years.
Below you will find fuse box locations, layout diagrams, and photos of the power distribution centers. Fuses for critical components such as the “Cigarette lighter” and “Fuel pump” are highlighted in bold.
In the passenger compartment
The cabin fuse box is located on the driver’s side behind the lower dashboard panel.
