Yea so I was cleaning out my car, vacuuming the carpets and I notice that my rear floor mat was bulged upwards. I go to straighten it and it is straight. I pull up on the carpeting and notice that the plastic casing for all the wires that runs under the carpet has busted from its mounting points and is being forced upwards. WTF im thinking to myself and I look at the opposite side and it is even worse! The carpeting is all deformed and the same bulge is present. About 2 months ago I replaced all the seats in the car and surely would have noticed this problem then. So I conclude that this has happened within the last 2 months. You know what else I did around 2 months ago??? I lowered it. I am pretty certain that from lowering it the subframe couldnt handle the pressure and something is warping. My car rides fine, but certainly something is not right. She is going to BMW tonight to have it diagnosed. I will keep you guys posted..
