I changed the oil and while just driving a couple of miles and driving back home noticed a tremendous amount of oil in the driveway. So took down the underneath protector and the seal is so bad that I can see part of it and is leaking constantly. I have an extended warranty through BMW My car has 70K miles and the warranty is to 90K and I have almost two years left. Called and is covered. I am having it tow on the 27th because that is when I can have a loaner. Will let you guys know the end result. I will have them checked on everything else since I have this coverage and no deductible. Oh Btw is a 2013 EB M sport 335I F30.
