I have a 2014 335DS, got a leak in the bedroom in the area behind the fuse boxes about a month ago. Found that the seal on the roof between the end cap beside the trim rail had a crack in it. The water was getting in and coming down the end cap, where there is a wiring chase, water got into the wiring wrap, and worked its way into the area by the fuse panels. So it is out of warranty, and figured i would just deal with it on my own. So i bought Eternabond tape, you can get it in black, tan and white, and taped over the trim rail from the drip rail on the side up to and over the dicor on top of seam, did all 4 corners of the roof. Used black on the front, tan on the back, now i will never have to worry about water getting into the seams on the front or rear end caps again. Going to run white Eternabond tape on top of the roof, over the dicor sealant all the way across both ends. I noticed a bulge like in some of the pictures earlier in this post, if i see any cracking at all i will be covering them with Eternabond as well. If FR is going to fix this up for other owners then i would like to hear about it, might just chase after them as well myself.
