I have 2016 M3W, bought October 2017. I am the second owner. Almost immediately i noticed small drops of oil appear on the garage floor after i go for a drive. Dealer assured me its not a big deal. The source of the oil is a big hole in the transmission housing. I have pictures that show the source. Dealer told me its transmission oil vapors that settle on the bottom of the housing and slowly drip when i park. Anyone else? I would say 2-5 drops are on the floor the next day. is this fixable? warranty? any help would be be appreciated.
