The Volkswagen Jetta 6 generation was presented in 2010 in the USA. Sales began in Europe in 2011. In Russia, this car was produced in 2012, 2013, 2014, 2015, 2016, 2017, 2018 and 2019. During this time, it underwent a restyle. In this publication, we will provide a description of the fuse and relay blocks of the Volkswagen Jetta 6, show diagrams and photos of the blocks in which they are located. We will highlight the fuse responsible for the cigarette lighter. We will also show the location of all electronic control units and offer a service manual for downloading.
