Here goes my attempt at showing you my fix for a convertible roof which leaks at the corners. Could possibly work if your roof leaks in other areas along the front seal.

When I bought my car in the summer, I didn't worry too much when I got a wet leg every time it rained, I just put a bit of kitchen roll in the gap and made do.

I researched this forum and saw other convertible owners suffered much the same thing. Reading up on the internet I watched people using silicone on their cars, so I too tried using silicone on the front seal to no avail.

Seeing as it costs hundreds of pounds for a replacement at BMW (even then it's not guaranteed to keep the water out) I decided to see if I could fix the leak myself.

My apologies for the noddy guide, but I'm an engineer and understand some people need war & peace for the simplest of tasks:hihi

Firstly, have a look at the seal, and see where it has aged/cracked/perished, as it is through this part where the water is getting in. In my case the corners.

I had a look online for a small adhesive backed rubber seal which would fit comfortably where the roof comes into contact with the top of the windscreen. Without being so big as to cause more problems than it solved!

I got a 1m length of seal from this website:

http://www.sealsdirect.co.uk/index.asp item no.SRS1706

(cost me about a fiver - 3.99 of which was postage!)


On a dry day (which is the most difficult part of this job with the recent change of weather!) open your roof and clean off any grease, dirt etc from the top of the windscreen - where the roof comes into contact.

This will help the seal to stick.

Once the windscreen is clean, cut your seal to the required length.
(Picture 1 shows how long I cut my seal & where it's positioned. It's flattened a lot near the corners since fitting)

Stick the seal down with the flat part of the seal to the front. (Picture 2)

Once you have made sure both sides are stuck down securely, close your roof (hope for the best) and leave to set. Leave for a day or 2 before/if you need to open the roof.

Now, hopefully, your leg will stay dry and you can stop robbing the kitchen roll!

Picture 3 shows just how wet it has been this week and I haven't had a drop of water get in - other than the ones I had taking the pictures for you!

Hope this helps, as you can see, if it works, it's a cheap fix, even cheaper if it wasn't for postage! Let me know how you get on.:thumbsup

I'm getting really stressed with mine now.
Over the weekend, while parked up, it has leaked and completely soaked my car through. Leaking in from exact same places as this.
I think my problem is with the corner piece of the seal at the top of the piece that runs up the a frame. There seams to be a little lip which will channel the water outside and down your window. When I close my door, it is very hard not to catch this flap of rubber and lock it inside/under the glass. I would assume that when this happens, all the water will be channelled inside the window rather than down the outside.
I will try and bodge it, who would be best off going to see? Maybe a mate who does double glazing or something?
What did you stick your rubber seals down with?

Thanks for the info and any more you can offer.:eek:ptimist

E36 convertible leaking roof Cure.

I had water dripping from the join on both sides of the roof where it joined the front pillars on my M3..
I tried everything from new seals, silicone here and there,vaseline, pieces of string to pad out the seals.....nothing seemed to work.
Then I discovered it was water ingression through the canvas itself which acummulated in the run above the windows inside the car and eventually overflowed at its lowest point.
I treated the roof with "FABSIL" which is an amazing proofing product which literally allows the water to run off like "water off a duck's back". Problem solved! No more leak!
I really hope this obvious cure helps someone as I know what it's like to have wet seats!

Hi mate

Thanks for your post.....going to give it a go....

Was on the website you got the seal from but cannot find SRS1706....there are SRS19.. so was just wanting to double check the order code number...

Also what did you use to seal it down with?

Thanks

Hi, thank you for the guide! :)
I'm waiting for good weather so I can take off the hard top and check the seals!

Currently, there is a little amount of water dripping from where the windscreen window and roof meet (on both passenger and driver's side) - which means we both get wet legs when it rains :(
do I need to put a seal all the way along the top of the windscreen? and along the corners?
and why use the SRS1706 over any other product the company sells?

Thank you so much!!!
Mike :)

Do you have any more pics on the positioning of the seals?
I have the same problem with water dripping but it happens with the soft top as well as the hard top so im hoping this will fix it.
Have ordered the seal today, what did you use to stick/bond it with?

Thanks for the info in the post - i was stuck wondering what might fix the problem.

This looks like a good solution to a common problem, will try myself at the weekend, only thing to note is my seals seem to be in excellent condition !

Also the op did say he looked on-line for a self adhesive seal so i'm guessing that's what he got and that answers the fixing questions !!

Hi this looks like a great idea but can I trouble you and ask how the seal meets at the corner of the windscreen and roof - ill admit to being a numpty at stuff like this.

Thank you for posting this. I picked up my first M3 convertible two weeks ago. The first week was sunny and great! The second, rainy and dripping from the same corners. I'm going to look for this seal locally today and if that produces no results I will order online.

I followed this advice trying to sort out our leaking z3 roof. Unfortunately it didn't have the desired effect and it continued to leak, therefore I found a way to rectify the flaw shown -> here <-.

We now have a watertight sealed z3 :thumbsup.

Hi mate, thank you for the guide. Really appreciated the well written instruction with fotos :D

Bought my E36 M3 vert couple of weeks ago. It came with the hard top fitted. After a couple of days of heavy rain i noticed my car was letting in drops of water where the hard top meets the top windscreen on the o/s (drivers side) A-pillar. I had placed a bath towel on the drivers seat to catch the drops and after 2 days of raining the towel was soaked, to the point where i had to put it on the radiator to dry out. I did this with alternate towels till i could find a solution to the problem. Also the weather never let up for next 2 weeks or so. The n/s (passenger side) A- pillar seemed to be fine no leaks at all.
I went to investigate and to my HORROR the foot well on drivers side was damp as well. Having searched these forums i decided to try the Vaseline on the A-pillar where the hardtop meets the top of the windscreen on the drivers side and this did reduce leak but did not stop it.
The damp foot well was due to another issue, it was the vapor barrier which hadn't been sealed properly behind the drivers side door panel. Once I sealed it no more damp foot well.
Having further researched this topic in this AWESOME forum, i found that using petroleum based lubricant it would actually dry and crack the rubber seals overtime. At this point i decided to remove the Vaseline and apply silicone based grease. I STILL had this damn leak and still having to place a towel on the drivers seat. After much deliberation i decided to remove the hardtop and give the soft top ago. I put up the soft top on a couple of days ago and this was letting in water from the A-pillar on drivers side and also about 6" in just above the drivers visor. The passenger side was fine. This was worse then the hardtop.
Eventually today this morning i decide to fit the seal as described by M9RC. Lets see how we get on. The dark clouds are moving in as i am typing this.
I'm hoping this seal will stop the water coming in above the visor but not to sure about the leak on the A-pillar. As i was finishing the job off i noticed a hair line crack on the rubber seal which sits on top of the A-pillar and goes around drivers door frame.
Gave the stealers a call for the black rubber seal for drivers door frame and was quoted £232. I'm hoping it wont come to this. Fingers crossed.

I will post the outcome after its rains today.

Curtangle - many thanks for your suggestion. I have the same problem and have been trying to stop it for ages, I checked the seal with the drain lip and found it did the same with my car when the door closed. All I had to do to release it was to drop the window and raise again. If I close the door with the window open then raise the window with the key (hold the key in the door locking position for a few seconds), the seal is positioned correctly. I also put a little smear of vaseline on the seal where the window glass locates and that seems to help - but not all the time. I'll let you know if the leak is cured after we have some more heavy rain.

My desire for heavy rain was quickly answered! The problem remains. I think I'll try changing the front seal above the door window.
