Looks like I got a leak on my shark fin that has slowly been damaging my tcb unit for the emergency call system. I've been trying to read everything on this common issue and found that there is a class action lawsuit recently filled against bmw for this!! Hopefully they take responsibility for this issue and recall it.

A little crazy they know of this problem and have refused to cop to the design flaw.

Looks. Like this is a 2300 dollar repair and bmw doesn't stand by there flaw !

Seeing this problem in here, I'm going to run a small bead of silicone seal around the base of mine before this bites me, too. (Taped and nicely sealed, or course...)

It's sad tho for 100k vehicle to put silicone on a design flaw. Bmw should step up and just fix it. Noone is complaining it happened but not to stand by there product is sad
