In my 2013 Mii left water ran into the trunk without rain. The reason was the already known from the Golf VI riffle hose in the rubber cover to the tailgate, which was broken. I patched the first with thick self-welding tape, since I rarely use the useless system anyway and only need it for the TÜV. If I want to replace the hose completely in the area of the rubber cover, the sky has to go out, doesn’t it? At the same time, I found that also the rest of the wire harness overwhelm In the photo you can see only a part of the broken insulations. Actually it is all pipes except the brown and white, which were led separately on the water pipe. The reason besides the inferior cable quality is that the tree is wrapped only one piece in the rubber cover pure with this textile tape, that then abruptly ends. At the place it pinches especially strongly then, so that the pipes break. Who saves the fun to patch in a new wire harness, Will, maybe you should join me and wrap the tree on a larger scale…
