Hi guys, I know this is a common problem water in a Z4. I know it's not the third brake light I have taken that out and sealed it. The covers over the lights I have poured water around there and no signs coming in through the fittings. Is there any chance you guys can point me in the direction of drains on the vehicle , I know the two roof drains are ok . It looks to me like it's gathering from the top of the battery as the plastic casing that the battery sits in there is a small level of water all around it. The seats in the front are dry . Any help would be much appreciated. Cheers Adrian
 
ONly other ingress options I can think of are the vents behind the carpet near the rear light clusters or ingress via the battery well itself.
I plugged the drain holes where the amp sits in the battery well, as well as waterproofing the bottom of the amp.
There are also drain holes in the battery compartment where water can get in as well as out.
Have you been driving it on wet roads?
