Are you sure its the seals? - passenger microphone/door jamb/water on the all-weather mat. Points at the drains that run down, get blocked slightly and let water back up and sit in there - eventually leaking out into the car via exactly these places.
Have you tried slowly pouring water down the drain holes at the front of the sunroof? Water should be running out from under the wheel arches. It should be running out at the bottom, not slowly draining away. When BMW blow air down the pipes, it often doesn't clear at the blockage is usually right at the bottom of the drain and the air escapes way before that. Mine were clogged on both sides and I used a very small and long wire snake brush cleaner down the drain. I took awhile to get it around the several bends, but I kept going and eventually the 2 metre long metal pipe cleared the blockage. When I poured water through the drain holes at the top, it was pouring out by the wheels. Once clear, I poured hot soapy water through the drain holes until all of the muck and gunk was gone and the water was running clean. Don't expect BMW to follow the same procedure, they will blow air down it, replace the seals and say its all fixed... Last edited by csm7djs; 04-04-2024 at 10:42 AM.. |

I can say with near certainty that wasn’t the point of ingress for my car. while water leaks can be insidious, I can’t picture a route from the shark fin to above the front passenger seat as the headliner was completely dry aft of that seat. I also installed a carbon fiber shark fin cover over 3 years ago

Water leaks are so annoying most likely it’s the drain tubes that rundown the pillars. They’ve probably got a kink on them. You’re gonna have to get them to take them out and install new ones. Something is small Particle can clog these up

Update -
Sunroof replaced. Upon taking down the headliner they ‘evidently’ noticed a crack in the cassette frame. 10hrs labor (warranty). Has not yet rained so we will just wait and see…and I’ll certainly update if it starts leaking again… |

Marty, it wasn’t my regular service advisor, so the service advisor I picked it up said the crack was in the rear, and that’s all I know. Sorry I didn’t get more details for the group.

That's ok, it is what it is. Being in the rear makes it almost impossible to see without removing it which none of us would do anyway. I think I recall a few others saying they also had a crack and had to have it replaced. That's why I was asking as I'm wondering if this will become a trend with age.

got my car back today after warranty replacement of the weather stripping and clearance of the drain tubes. they ran water on the sunroof for 2h without any leaking noted. hopefully a repeat incident won’t occur and find the frame is an issue as they did not inspect for it even after I mentioned it to them at drop-off

my SA showed me their list of common service items outside of warranty (so they have the equipment necessary), clearing drain tubes being one of them at a cost of $130 (though he got mine covered under warranty) |

When I took the cowl off his car I could see the water pool, wish I had taken a pic of it cause it was a LOT of water sitting in there. Here's a pic of what the drains looked like after we sucked the water out. The drain holes are about 1" x 2" in size and were completely plugged with years of debris that had decayed and become quite hard and packed. . |
