Seat Leon 2016 | Water Leak Detection

Video transcript

0:00 OK, today we have a Seat Leon in today 2016 for our water leak procedure. So we're just going to show you what we've found through our test. So focus is on the passenger front door to begin with. It did originally come in with water coming in the boot area, but my colleague's just going to put a bit of water down the back of the window to simulate and say that it's raining. And if we look very closely, we can see that there's a run mark coming out from the bottom of the door membrane. And then what that would then do

0:27 is it would sit on this rubber seal. Then when it builds up, it will then slowly work its way in. And we have checked underneath the carpet, there doesn't seem to be any moisture or any water under there. So obviously we have to note that one, and obviously if we replace that one and fix it, we normally do all four because they're all the same sort of age. And coming into the boot area, and so this is where obviously the customer is finding the water in the spare wheel

0:49 holder. We've got the rear hose up behind the rear bumper to test the rear air vents. And if we just quickly come behind here, we can see the air vents there. And if I just quickly focus my camera in, we can see that the water is coming through the air vent, but as well as it's coming in through the bottom. So we can see here there's a giant puddle here. Once that puddle fills up, it will then work its way over this step, and then it would then fill up the spare

1:19 wheel holder. And so there's, it's leaking quite heavily. They're both leaking on either side, so we would obviously have to replace them. And so there we go, that's what we found so far.

Here we have a Seat Leon with wet carpets, and although there is evidence of leaking through the door membranes, this doesn't tally up with the large amounts of water in the boot.

Upon further inspection, the culprit is the rear air vents, which we will address. Sometimes if the air vents are leaking from around the seal, they can just be resealed, however these vents act as a kind of one-way-valve which can wear out over time, in which case it's best to replace them. They can also get clogged with dirt which sprays up from the road.

We would recommend the carpets be lifted, and the car properly dried overnight.
