So after a nice Westcoast rain strom...i spotted small drops of water coming down fron the sunroof switch and the drivers side floor mats completely soaked.
Brought the SAV in for some work under the BMW certified warranty and mentioned the leak in the switch and wet floor. They call ma a couple of days later saying that I have a crack in the sunroof housing and it would cost me $2040 (which includes parts and labour) to have a new one installed. This was the problem for the leak in the sunroof switch. Then they mentioned that the would not look at the floor until they fixed the sunroof since they believe this might be the cause of the floor leak....and the kicker, not of this is covered under the certified warranty.
Now....it this full of crap?

Just wondering what you guys think, am I getting the run around? How can a small leak in the sunroof make its way to the floor board on the drivers side only?
Has anyone replace a sunroof housing? Anyone have pics/instructions for a DIY and should i tell them to sill lift up the carpet and check the floors for the leak?
