Mini Cooper Convertible Water Leak

Video transcript

0:05 Do you want to sort of show me through where you were finding moisture and what the... The whole carpet is wet. They're both wet on both sides. OK, both sides, yeah. And you can feel there's nothing on the top side, it's the underside just soaking wet. Someone showed me, you lift up the carpet and it's under the carpet, it's all wet.

0:27 I've got you. What I noticed, I've got photos I can show you also if you want. I get, on this side sometimes there's water dripping from about over here inside, by the just like the metal of where the roof comes in, yeah. Also sometimes I get condensation all the way along here, it's gonna be quite wet, a lot of the cold parts. Also sometimes when it's raining and I open the roof, as I open the window, I'll get dripping down water from here onto the carpet. Yep. So that's the only actual water I see. Okay. From it dripping into the car during rain.

1:04 Yeah, if I open the window. So it's probably, this is probably squished. I'm assuming this is a common thing on Minis. Okay, this is probably squashed, so it's not going down there, it's come out properly. There's contest that there was water in the place where all the tools were. Yeah. Yep, that's where I found water once, and then also here, it's kind of the same issue. I probably need from that thing, there's water that comes, I mean it's a bit wet because of the step, but there's water somewhere that comes next to the speaker, just over here.

1:39 Okay. Water comes in, not through this canker, but next to there. Okey dokey, no problem. Have you taken it anywhere else to get it looked at at all? So I took it to one place which was close to me, that's when they showed me that there was water underneath. And he just said, he assumes it's gonna be these.

1:57 Yeah. But I figured I might as well get it checked out properly, as opposed to just an assumption of what the issue is. Okay. Any electrical issues or anything like that at all? I had, the airbag sign was on, but I just went for a 70 two days ago and they just cleaned the sensors and it was fine.

2:17 Okay. All right, no problem. There's no concern there. When you park your car, how do you park it? Do you normally park it flat on a slope? Yeah, which is flat. Okay, no problem. Apart from, obviously, the water leaks itself, any other bits and pieces you'd like us to quote for whilst we got here?

2:32 No, just the water, anything else is fine. Yeah, just sort of focusing on the water. Okay, thank you. No problem, so both sides and in the boot, yeah? Yeah. Gotcha. Have you sort of had any ideas, if you were to guess, you're saying probably the drainage? I'm assuming it's the drainage, the water, like I said, the water comes straight down from here down.

2:50 Yeah. It goes around, there's water usually on the stair. Yeah. That part, that's personally what I think. Okay. Okay, you know, it's just any mould or anything like that? Yeah, I got you. There's definitely mould in the car, it's in the seat belts, it's very adequate. Any reason it's not as bad as it usually is? Yeah, I get a lot of condensation in the rear of course. Yeah. Okay, all right. So I can't remember what's brought in a Mini Cooper and complained that once we've been in the front wheels, both front and rear, if we grab our

3:22 we've got our moisture meter here, you can see, so that's damp. So yeah, that bit's soaked. If you go out to the driver's side, that'll check. So this one's soaked as well. We can move it forward. Check the rear just because when you have water in the vehicle, it can move about, just depending on how you park.

3:56 That one seems to be fairly dry. But yeah, obviously I have water under the underlay, it's not particularly good because the underlay is just a big sponge, so it managed to soak it up, and because there's no airflow down there, the water is stagnant, so it doesn't actually get moved, it can't go anywhere.

4:16 So you can see this one is pretty damp, as you can see there. So that one's damp, but yeah, obviously we've got water on top of the footwell, so we're also actually showing the carpet. That's when you can get mould. You can see signs all over the appearance. What we do is we've hoped for an overkill in this one, just to get rid of all the bits of mould.

4:43 Also, the client said that he's smelt some mould or had some mould, so we managed to get rid of that. Right, so on this one, windscreens are a placement. It's not leaking, which is good. Air vents are leaking. Scuttle seems to be fine. I mean if we go around you can see, you see where these are actually pinched, so they're actually not letting the water go into the holes, little drains there. The water is just missing that and coming into the car and dripping down. Same on the other side, if you take a look at the other side, you can see the walls are

5:28 actually not going in the hole, so when it overfills it just goes completely through where it should be, it drains straight out. Also on this one, these door rubbers aren't sealed on at all, so obviously we do the door rubbers. Door membranes are good on this one, which is good. We'll take a look at the back as well, we can see this tailgate rubber is very loose and it's not sealed on, so obviously water can get in there and then run down, and that way it can make its way through the vehicle.

5:59 So yeah, what we do is we try to do all four, I mean all the door rubbers, seal them up. Also with these, what we're going to do is we're going to take them off, Krytox, clean and flush them, because this is the actual sun roof drain pipes. So what we do is we flush all the pipes, make sure they're working perfectly. When we Krytox, clean them up, so they're basically given a nice seal so that if they last longer they won't crack.

6:30 And then in regards to drying this one, what we'd have to do is take out all the seats, lift up all the carpets, suspend the underlay in the air so that way there's no stagnant contact or anything. Because if the underlay is touching the side of the metal or anywhere, then the water can't go anywhere, it's stagnant.

6:47 So what we do is we pin it all up, make sure it's all suspended in the air, and then we'll get our water lapped in there, suck as much water out as we can, and then we will get our drying machines in there. Both footwells are wet, that rear passenger side over there is fairly wet.

7:07 This one's not so bad, so it's probably going to need about two to three nights. I'll have to confer first, but yeah, it's going to be two nights minimum, three nights maximum. Also what we do is we recommend to get these A-pillars done, because they're very common on these cars. So what we do is there's clips under there, and what happens is where you're going down, say for example you're going down the motorway, and the water's hitting it and setting more an hour, so it's going in there, and it can then go in the clips. It's just

7:36 a very common thing on Minis, that's all. So what we do is we take them out, get complete new clips and seal them up and put them back in, make sure that's all nice and watertight. But apart from that, I think that is all. Okay, just a quick update video for you. Obviously the seats are out, you've got the rear seat over there. They've all been cleaned and we're just going to pop them back in to get all dry. But just thought it'd be interesting, I'm just going to get my colleague to pull

8:03 this bucket. So this is obviously what has been inside the vehicle. You can see the soapy layer on the top, that's obviously where our conditioner has done. But if we get my colleague to pour down the vent, you can see that sort of dark, dirty water, and that's all the dirt and grime and stuff that's come out of the seat. So definitely worth doing. You can see all that silt layer at the top, and if we look back in the bucket now, you can see all that

8:33 the bottom. So yeah, just to demonstrate that it's definitely worth going ahead and getting all those seats cleaned. Okay, just a quick video of the Mini with it being on the test start, so it's just right to take it out in the storm. So we're going to leave that on there for about 15-20 minutes, make sure it gets completely soaked, and then we'll have a check inside and make sure that it's all dry.

This Mini Convertible had water leaking in and both front foot wells had wet carpets. We found the door and boot rubbers were loose and not sealed in properly.

The moisture meter found both front footwells soaked. We also found that the roof rubbers across the tops of the doors were distorted and not doing their job of channelling the water away from the windows. The car also had mould caused by standing water, which in turn caused bad odours.

We properly fitted the door rubbers, and cleaned and conditioned the roof rubbers to solve the leak. We also recommended waterproofing the locator studs on the door pillars, as this is a common problem on Minis.

After fixing the leaks, the interior was decontaminated, shampooed and dried to prevent mould.
