Volkswagen Transporter (T6.1; 2019 – 2021) – fuse box diagram

Posted on 8 September 20249 September 2024 by admin

Volkswagen Transporter (T6.1; 2019 – 2021) – fuse box diagram

Year of production: 2019, 2020, 2021

The Volkswagen Caravelle and Multivan are very similar both in terms of technology and exterior design. The key difference lies in the interior trim and panels. Both models are built on the same platform as the VW Transporter and serve as its passenger version. This article covers the seventh-generation Volkswagen Multivan (T7), produced from 2022 to 2024, as well as the facelifted sixth-generation Volkswagen Transporter/Multivan (T6.1), produced from 2019 to 2021. It provides details on the location of the fuse panels and explains the function of each fuse (fuse layout) and relay.
