SEAT Leon Copa Part 2 | Leaking Doors & Screen

Video transcript

0:00 OK, so onto the windows now. What we've got is we've got a high-pressure hose going in the inside of the window. If you want to go on the outside, what we're going to do is we're going to spray a bit of bubbles up in this area here. Can you see that bubble in there? So that's where the leak's coming. So the leak looks like it's on this welded sill here.

0:27 The problem is, we're not too sure how far that leak goes up. So what we're going to recommend is two hours investigation. That means we strip off the front wipers and the scuttle area and see if we can just reseal this. If we can't get to the top of the seal, the only way of resealing this would be we would have to take the front screen out, then seal it, and then reset the front screen.

0:52 And so there we go, but that's the main one which is fueling the problem there. So that's what we've found.

Testing the front screen shows that there is a leak in the welded seam for the windscreen surround.

Unfortunately, we don't know how far that crack goes up, or if water draining behind the screen flows over it. Without removing the screen, it is hard to know. So our best option is to remove as much trim as we can and seal what we can, then re-test it for leaks. If it is still leaking, the screen will need to be removed to gain access.

A crack in the weld does NOT mean the whole car is falling apart. The car is constructed with spot welding which is not waterproof, so in order to make it so, the welds are sealed with a putty. Over time, this putty hardens and can crack.
