Roof leak on both sides…..

[Sebastalona]

I have water ingress into the cabin on both sides. I did a trickle test, and can see the water entering the cabin at this seal:




This is the internal view of the seal between the two shells (found on a YT video):


I’ve recently treated all the seals with gummi pflege but there is obviously a bigger issue?

Does anyone have any suggestions on where to start resolving this? I’ve put a rain cover on it for now, but I need to resolve this.

You could try some silicone rubber grease on the joint, I use it on all my rubbers as well as the gummi pflege

Thanks for that. Ordered a tube and collecting today. I’ll give all the seals another good clean, re-apply the gummi then apply the grease. I guess that’s the only option available to me now. Had a look out of curiosity at new seals and the price isn’t far off the value of the car!

Including fitting or not?

Supplied, not fitted. Granted I only looked on Sytner BMW’s page as I’ve bought parts from them before, but even a quick Google search doesn’t find the parts any cheaper.

If it’s a compression issue, is there any way to micro adjust the roof shells? It operates absolutely fine, and when I applied gummi last time, all seals looked to be in good condition.

Thanks for this. However, my issue is the seal between the two roof shells rather than windscreen frame and roof shell.

FWIW mine used to leak from the front trim and whistle with the wind...it magically fixed itself with some trim nourishment,,

TIS has all the details..

Thanks for all the replies. I’ve retreated the area on both seals with gummi, and also applied a layer of silicone grease on both.

Again, all seals look clean and in good condition, and they seem to mate fine when closing roof.

I should say that last night the rain was biblical! I can’t say I have noticed ingress when driver, but I suppose the water isn’t having time to run down when moving through the air.

Hopefully this will do the trick.
