Hi guys. In the process of converting my 2017 mk8. Come across a water leak in the column directly behind the sliding door. We have removed and sealed a bolt which is located there, we have sealed where the door mechanism cable comes in slightly lower. Still water leaking in when we hose down the door rail. Hard to track the water as we are having to peer in holes in the column and its very inaccessible.
Does anyone have experience of fixing a leak from the sliding door rail or has anyone changed the rail for other reasons and can advise whether this is straightforward to removed? then we can seal with sikaflex and stick it back on.
We've run water on the roof without it running over the door and there is no obvious water coming from the roof. There is so little on that side, literally the cable and bolt we have sealed, a rubber circular seal at the top and the rail.
