Ford Fiesta | Rain Water Leaks

Video transcript

0:02 Hi there. So today we have a Ford Fiesta in for a water leak as well as odour. So what I'm going to show you right here is our moisture tester. So if I turn this on, it straight away beeps at us, which shows that the floor is wet. So there is water coming in from somewhere.

0:24 This is especially important to get sorted out this time of year due to the weather being quite damp. So it's not going to dry out by itself, so that is something that we would recommend getting sorted as soon as possible. This can also cause mould to build up in your car, which we have seen already, as well as the strong odour that you have mentioned to us. This can also cause electrical problems if the water were to get to any of the wiring underneath the floors or behind the dash

1:01 area. But what I'm going to do next is show you what we have found, which will be in the door membranes. So what I'll do here is I will get a bucket of water, and then we'll see some drippage coming down from here. Okay, so now what we're going to do is tip a bucket of water down the window here, which will simulate rainfall. So what's supposed to happen here is water is only supposed to come out of these small holes, but you can see under this plastic here water is trickling out

1:43 quite a lot. What this can cause is the wet floors that we have found. This is on all four door membranes, so what we would have to do is strip this whole plastic here, take it all off, reseal all of that, so the water is only coming out of those drain holes and not into your car.

2:05 Okay, so moving on now, as you can see here your scuttle area is full of debris. So this also is a drainage area for water to go through, but with it filled up like this, that prevents the water from trickling all the way through and could end up, like, inside the vehicle.

2:27 So what we can do is clean that all out and make sure that the water is flowing nice and smoothly through that. Moving forward, we can see here that your rubber seals are quite loose. So what this can cause is, when water comes onto the roof, rain can trickle into this seam here and then all the way down into the footwell, which can also cause your wet carpets. These do need to be fully tight and sealed, otherwise rain can find a small little gap and get through.

3:04 This is on all four doors, so that is something that we will need to sort for you. And then we've also got your boot seal here, so it is once again also quite loose there. So that just all comes off very easily. It should be proper tight and sealed onto the metal framework, just to prevent water from coming in. So that is also something that we will do for you, which just seal that all up for you and then fit it all on there nice and tightly, to prevent any water access in the vehicle.

3:38 We have also got some rear air vents behind the bumper area, so if I can show you there. So it's just that black plastic that you see in there. So it's quite common on Fiestas, so you have one either side, which is just underneath the light, so around about this area. So when water is put onto this area here, water does leak through, so that can cause the water in your boot, which we have got just under this wheel here. So what we will do for you is remove this bumper,

4:16 remove the lights, and then we will replace those air vents for you and proper put that all back together and seal it up, so then you won't get any more leaks from that area. So what I'm going to do now is I'm going to show you the welded seams. As you can see, you've got a very small pin hole which is bubbling up over time, and that's going to allow water into the car to trickle down and into the boot. And then if you come

4:55 round to the other side, this side's even worse. So just find the right spot. So again, obviously you've got that welded seam all the way up here. So we'll just find the right spot for it to start bubbling through, as you can see where it's been blowing up previously. There we go, you can start to see a lot of bubbles coming through. So again, that should be an area where you're finding that water in the vehicle, and that should be all coming the right way. So that is everything that we have found on the Ford Fiesta, so what we will

5:35 do next is put an estimate together for you, and we will send that to you via text and email, and you'll also get this video sent along too. Okay, just thought we'd give you a quick update on the vehicle. So we've stripped all the door cards there all off on both sides. Obviously the seats have all come out as well. We'll just like to take some of the trim up as well, and there was this bit here and it was just sort of loose in the car, so we're not too sure

6:07 where that's come from. We can try and figure that out for you. I believe it is part of this car, but yeah, just wanted to say that we found that underneath the seat. Apart from that, I just wanted to show you that obviously we're getting on with it all, and there are a few bits and pieces where, I say, you start to see bits of mould in it and stuff, which is obviously gonna be causing some of that smell. And you can see on the headliner a bit more there as well. So obviously

6:34 we're gonna go through the order repair work, get it all nice and clean, and it will be looking really really good. So we've ordered the parts and stuff. They will be on our way, probably get those Monday or Tuesday. But yeah, just wanted to show you our progress so far. We've also taken the scuttle area apart at the front, because that was obviously draining slowly, and you can see how much it's just built up over time. It's just a lot of, you know, leaves and stuff that mulch down. So yeah, just wanted

7:09 to show you that. It's already making good progress on it. Okay, so just a quick update video for you on the vehicle. The door membranes are all done, they're all sealing, and what we're doing now is we've got our smoke machine in there. As you can see, it's just been turned on, and that's basically going to help to deodorise the vehicle. That's got a really nice neutralising smell in it.

7:32 It doesn't really have a particular scent to it at all, so it's just very neutral. It's going to help throughout the vehicle. Coming around to the front, all these scuttle areas have been taken apart. All of it underneath, we can kind of see through there, all being cleaned out. We've got all pictures of before and after of all of that. And then all the scuttle drainage has all been cleared out. So that's all really good. Obviously you can see the bumper's been taken off. We've just put some old cloths in the holes for now,

8:00 just to seal them up, just to not let any smoke come out. But obviously, that will be resealed shortly. You see a little bit of smoke coming out just from the back, obviously, where the rubber goes and off of the rear lights. But all of that will be sealed up as well. So we're just waiting on the rear air vents to arrive for those.

8:20 They should come in the next couple of days. But yes, we'll let that sit in there for a while, let that all smoke before we go through onto the next stage with obviously cleaning. The seats are all out there ready to be cleaned as well. So on the surface they don't look too bad, but obviously when we do start to clean them we'll show you how much we get out of them as well, and obviously all your parts there and everything like that. So yeah, just wanted to show you a

8:49 little update on there, just show you that we're going along nicely at the moment. And yeah, we'll be making some big changes to the vehicle soon. Okay, just another quick update video for you. So all of the door cards are all now back on. We've just shampooed the carpet and the rear seats there.

9:10 My colleague is just going through and shampooing all of the carpets and all the mats and everything at the moment. We're gonna put the normal Fiesta mats, the black ones, in, and we'll just put the grey ones in the boot now, obviously, that they don't quite fit at all. So yeah, we'll just pop those ones, they'll still go back into the carpet, they'll go back into the boot for now. So that's obviously a hot extraction, so that's going to be pushing hot shampooed water into the carpet, or into the seat in this case,

9:42 and then it's actually sucking all of the dirt and grime out of it. So if we just have a little look, you can see all of that. That should obviously be a clear colour, and you can see that's just obviously the years of dirt and grime fills up. It's just obviously, you know, when you're sitting down on the seats a lot, it's very common. And again, I feel, so we're doing that on all the fabrics inside the vehicle. But yes, we just

10:06 show you that obviously we're making good progress throughout the day. So just one more quick video for you to end the day. So obviously this is the water that we've extracted from the vehicle, and that obviously just shows you, just over time, what gets built up inside the car. And then what I'll get my colleague Max has shown me is just inside the bucket. In a second you can see all of their sludge and everything that builds up, which is all coming out the car,

10:32 fixing up the seats and everything. So really good. The odour, we're about halfway through the odour removal process as well, so the car's already smelling much better, no longer has sort of that damp smell to it. So yeah, that's probably all the updates you're going to get today. We're going to try and get this stuff back in the car, and so the car will start to dry tonight, and we're probably going to put some of our bigger machines in as well, try and get it to dry a little bit quicker for you. But yeah, so obviously just keeping

11:01 you updated throughout the process. Hi there, so this is just an update on the Ford Fiesta. So it has just had its courtesy wash now, so it looks extremely clean and in tip-top shape. It is just now under our rain arch here, which is just simulating some rainfalls, just to test all of our repairs on the car, just to ensure there's no further leaks. So we'll keep this on here for about 30 to 45 minutes, just to get as much water in the areas as possible

11:36 to ensure that there are no apparent leaks. What we do say though is that because we'll need to go out in a real world test, so when you're driving it about, obviously water will stick up into other areas that may be missed by the rain arch. Hopefully all in all it should be fine, but just when you're out and about driving around, just keep an eye, just in case you do notice anything that wasn't showing up during our rain arch procedure. But yeah, we'll keep you updated. Okay, so we have our Ford Fiesta

12:18 here that originally came in for a water leak. This is the final update. It has now had its exterior courtesy cleaned, so it's looking much cleaner than what it was when it first came to us. It has also had the interior cleaned out, so it's smelling a lot nicer than original. The seats are much cleaner and looking pretty pretty good. The floors are nice and dry, which is happy days. So after all of our testing and the wash it's had, everything seems to be working as it should. It will still need its real life

13:10 test. So if you could check the car as you use it, so drive it as normal, park it as normal, and just check it, just to ensure that there are no leaks that have been missed. But everything should be working as it should. But yep, so this the final update. All nice and clean, all nice and dry, and we'll send you this video. Amazing!

This Fiesta came to us with wet carpets, and we performed our leak diagnostic service to find the points of water ingress.

The car was also suffering from odour problems and mould as a result of the water having been in the car for an extended period. 

The Diagnosis service revealed that the vapour barriers in the doors were leaking, air vents behind the back bumper were leaking and the seams at the top of the tailgate were also letting in water.

As far as we know, there were no leaks through the bulkhead, but leaves and organic debris in the scuttle area can block drainage holes, causing the scuttle to fill up, which can then leak through fixtures such as the pollen filter, so it pays to keep this area clean.

Solution
We replaced the rear vents, refitted the door and boot rubbers with a sealant, re-sealed the welded seams at the top of the tailgate and re-fitted the leaking door membranes.

The interior of the car was treated with antifungal, shampooed and fogged with a product which kills mould spores. 

When the car was put back together, it was given a courtesy wash and wax, and put under our rain arch for a final test to ensure we hadn't missed any leaks.

Conclusion
Although a lot of work was done on this car, it makes sense as the owner has already paid the cost of devaluation. After a car is three years old, it's cheap motoring, especially with a small, 5-door car which is perfect for town driving. Fiestas are reliable, run for years and parts are cheap, so if it's the right car for you, why not make it like new again and run it for many more years? While many people would look at an old car with lots of leaks and decide to trade it in, repair and refurbishments is far cheaper than the cost of a new car.
