    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

    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.

    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.

    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!

    If you are having difficulty finding SRS 1706, here's the link to the correct page on the Seals Direct website.

    Scroll down the page until you get to the Sponge Rubber Section heading, SRS1706 is at the top of the list.

    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
