0:00 Okay, today we have a BMW 5 Series 2004 for our water leak procedure. So we're just going to show you what we've found so far. So the first thing we're going to concentrate is on the sunroof. So what we're going to do is, we can see the trough here. So if I can just get my torch on up here, so we can see what's going on. Right, okay, so we're going to fill this reservoir up with water, and as we can see there the water isn't running

0:31 away, and so it's just staying in the reservoir. And if we just quickly look up here, we can see that the water is still sitting in the top rales. Now that should release through the front arch and the back arch, but as you can see there's no evidence of any water coming down. And so what is going to happen is, if we put a bit more water in that guide there, and then what that then should do is it should back up on itself and then come out where the pipes join into the

1:10 sunroof. So we can see that we've got a drip here, and as you can see it's getting faster. And then what that's then doing is it's dribbling down on the seat, and then obviously it's going under here, so we've got signs of mould underneath the seat. And if we push down here we can see that this is wet as well. As on the passenger rear footwell, we can't feel any wetness on the top, but if I put my hand down inside here where the earthing cable goes, or the live cable should I

1:40 say. There we go, so it's absolutely soaking wet underneath here. And if we now come across to the driver's side sunroof, and we're just going to do exactly the same thing, so if we put some water just in this front cassette. Okay, so we can see that the water's still sitting in this bar here and it's not going away, and then what that's causing it to do is it causes it to back up. And then what we're getting is we're getting water dripping out of here. So we can see just

2:19 here you've got a tiny run mark, and as well as it's dripping out of here onto here. And then what that's then doing is it's filling up the footwell. And let's quickly come round to the drivers rear. And drivers rear on the back seat looks like it's doing exactly the same on the driver's rear seat. And if we then put a hand down here, quite soaking wet under this driver's side. So there we go, so it's absolutely soaking wet under there as well. It has got thick

2:51 underlay, so it is going to take a bit of time to dry on this one here. So that's what we've found so far on the first lot of leaks. And so I'm just going to set us up for the rear, and we can show you what we found in the boot area. Okay.

This BMW is leaking from the sunroof. At this stage in the inspection, it isn't immediately clear what is actually causing the leaks.

But it doesn't really matter because there are a number of possible reasons, and they all need to be checked.

A sunroof could leak because the drainage holes in the cassette are blocked, causing the cassette to overflow. It could be that the drainage pipes are blocked at the cassette, at the opposite end where they drain out, or some place in between.

It could be that with age, the silicone pipes have shrunk and pulled off their connectors, or they could have split. We also sometimes see that pipe connectors become old and brittle, and they can crack or break. In addition to this, there can be other issues, such as the sunroof being so clogged up with dirt that it isn't causing a good seal and letting in too much water.

Whatever the reason, (and it could be any of them or a combination of a couple), they all need to be checked and dealt with. If it's just a blockage, then it's just an easy fix, but if it's broken connectors or shrunken pipes, the best solution is to get replacement sets and put in new.

The car has mould in the back which needs to be dealt with appropriately, and the car needs to be dried properly if we are to avoid the mould coming back.

Question: "My sunroof won't close properly, can you repair that too?"

Answer: We aren't really geared up to do repairs. We aren't a conventional garage. Obviously, we can do repairs and repair things in the course of our work. But if you have a something like a faulty sunroof, the hood on your convertible won't go down or the electric windows are not working, it is best to send it to a specialist who can fix those before brining the car to us. Keep in mind, though, this could all be related. Electrical problems are often caused because water was leaking into the car, which then means you can't properly close your window, so then even more water gets inside your car.
