Renault Clio 2008 | Water leaks found | Sunroof and Vents

Video transcript

0:00 OK, so we've got Renault Clio in today, 2008. We're just going to obviously show you what we've found so far. So first thing we're going to focus on is the panoramic sunroof. So my colleague's just going to spray, we'll put a little bit of water down where the channel is for the drains. OK, so we can see there that it's not running off. That's it, if you leave that there for a minute. So there we go. So we can see that that's not draining off there, and it should drain off through the front arch, so there's no water coming

0:34 out of there. If we just quickly go on to the passenger front drain and do the same again. So my colleague's just going to put a bit of water. There's obviously previous water still there from last time. Okay, so we can see that the water's not running away yet. So if we go down to the front arch, so we can see there's no forms of water coming in there at all. And the second one we've found, if we just come to the rear of the car, and we can see on this bit of bumper, we can see that's not lined up

1:08 properly just here, and we can see that this bit has been snapped, so it's possibly had a bit of damage on this corner end. Basically what we're going to do is we're going to stick the hose up the back of the bumper, and then what I've got is I've got a little twisty camera here, which goes down into the box section where your air vents are. And there we go, so we can see we've got an air vent here. Okay, so you can just see it's not the best picture in the

2:06 world. And but we can see just on the top edge there that it's dirty, and it is letting in a little bit of water, and that shiny point there is obviously a drip bit of water there, and then it's filling up the box section. It's not a heavy leak, but it's a tiny leak there. So that would be the rear air vent on the driver's side, which corresponds with damage. And as you can see there, there's a bit of dirt on that corner there, so it's showing that there's water passing

2:31 through. And if we just quickly come to the driver's side, what we've done is we've just lifted up some trim so we can get underneath the carpet. And if we just quickly lift up this driver's side, so we've got the carpet under here. And if we just lift this underlay up, give me a second, I've just got to get myself rearranged. Okay, so we can see down in that little hole there that we have a pocket of water, and so we can see how much water is actually under the

3:07 underlay. And as well as if we come to the back and we look underneath this carpet here, there we go, so we can see that it's completely soaking wet under there. So it's completely wet on the driver's side, but it is not wet on the passenger side. So that's what we've found so far.

This car had blocked sunroof drainage holes, blocked on both sides, which often causes problems as the water can then run down from the roof, but as there doesn't seem to be much water on the passenger side this doesn't seem to be the main culprit.

There is also a small leak on one of the rear outlet vents. As has been shown on many, many of our videos, this is a common problem on many makes and models of cars.

Even though we have found these three issues, it probably doesn't seem to account for the amount of water in the car, so we will keep looking. The results can be seen here.

Solution: The sunroof drainage holes can be unblocked and that rear vent will be removed and looked at and then either repaired or replaced; probably replaced.

Question: "How do I unblock the sunroof?"

Answer: The best way is with a sink and drain unblocking wire. You can buy them very cheaply on eBay, but sometimes it's hard from the photos to tell exactly the scale of what you are getting. What you want is one which is a thin wire coated in plastic with a tiny brush at the end.  You can get these at the hardware store. I think it goes without saying that you shouldn't put chemical drain unblockers down these holes, and we'd also advise again poking a coat hanger down there. The pipes are usually a fairly soft silicone connected together with plastic connectors. You need to be quite gentle to avoid damaging the pipes or popping off the connectors. 

If possible, work from the bottom, and sometimes it is possible to clear the blockage (which is typically at the bottom) with a few squirts of a hose pipe. Just take your time and be gentle.
