It's not exactly a leak, but I still get wet

So, I mentioned in another thread that I bought my first BMW. I've never really been into cars before, but I'm already planning on upgrades and additions. But first! A few small repairs.

After a rain, water will stored up in these thingies (I couldn't find any mention of them in theBentley Publisher's service manual):



When I turn a corner, the water drips out onto the person in the seat below. If Iturn right, I get dripped on, if I turn left, the right one drips.

When the roof is closed, I think the water is getting in through here:



So what goes in there to keep water out? Was there something there originally?

Suggestion on what to do?

It looks like you have some piece of rubber in your seal. I'll post a pic of mine in a minute to compare.

It's at the bottom of the curved cup in the corner of the windshield. It looks like you have some type of rubber grommet there that I don't have. They may have changed the design from 03 to 04.

For my car, the weatherstripping goes across the top of the windshield, down both doors, across the door sills, and up the rear of the doors. It's all one piece, and very expensive, like $450.

I've read people have fixed this issue by putting a bead of silicone behind the weather stripping on the front edge of the top. This pushes the weather striping out a bit and allows it to make a tighter seal.

If water gets inside, it is a leak. I had exact same problem. In my case it was torn weather seal on front edge of roof seal. I need a new seal. But it is expensive and I've not found a DIY for replacing it yet. Once I know how to replace it I'm willing to buy a new one. IF somebody knows how to replace that seal, please post here and let us know.

In the mean time I did the silicone/RTV fix described here

http://forum.e46fanatics.com/showthr...front+top+seal

That, along with Gummi-Pfledge to condition the rubber, seems to have worked so far.
If it starts leaking again - I'll either buy a new seal and try to DIY, or just try more silicone.
I wonder what BMW would charge to replace this seal - I'm afraid to find out - but might if
I can't stop leaking - like I said, so far so good.

For now I still carry a towel in the back seat - just in case. Can be used for many things . . .

The circled hole in your second picture is a drain. Water flowing in there should flow through the windshield pillar and drain out under the car. If that drain is plugged it could cause problems. But that drain is only designed to drain water outside the seal. In my case, what I think was happening is that water was getting through the seal (since it was cracked) then when I turned it sloshed to one side and dripped inside.

Again, Let us know if you find a proper solution to this - and what it costs, and how to do it. I don't expect my fix to last more than a few years - if that.

No, that's the water that spills into the cabin.

I didn't see that particular thread; I saw this one. I've already done that. Maybe I'll give it another go.

Ah! A man who knows where his towel is!

I've had the same problem in the past. There is a drain hole located there, it is clogged. You need to unclog it and all will be better. I was able to use an air compressor to blow air through it on one side, the other side I needed to use some thin, but stiff, but still flexible wire. I know that sounds like an oxymoron, but it's do-able.

Where does it go. Down the A pillar legs or just down the sides. Does it have a entry hole, where is it?

ok i found the drain...

drop your top, look down where at that corner rubber where the roof meets the A pillar...you will see a small gap and a tiny lil hole. thats it... that microfelt rubber on the side of your A pillar, the drain is BEHIND that... if you go to the bottom of the A pillar with the door open where the rubber gets smooth, you can kinda reach a finger under the upper part and see where the rubber folds, and makes a drain... follow that all the way up, stick a finger in it and slide your finger all the way back to the roof.
youll see.. mine didnt looked clogged at all, but i still used my finger to wipe out some dust on both sides.

Here u see my finger inserted in the drain and not inserted just pointing at it.
This is with the door open, standing looking at the side of the A pillar. Just to the right is that corner where someone took a pic of. Where the window, a pillar and roof all meet. Click image for larger version

This pic shows the whole from the top. It's visible top up too. Seem water fwd of the roof and rear of the windshield all gets channelled down these on both sides and drain out by the door/front fender gap where u always see water come from when u wash the car.

That's what she said!




I had a one-time vulnerability at that point. It was in a crappy touchless car wash. Both sides dripped a bit.

But it has never happened again since, even in very very hard rain like today.

You can adjust the top to close more firmly against the windshield. There are 2 bolts on either side of the top that adjust the final stopping point of the top. Adjust them down to bring the top closer to the windshield. Just don't go crazy or the locks won't line up with the windshield... as me how I know.

The nuts can be seen by pulling back the covers on the sides of the top with the top down. Tighten the bolt.
