Oil pan leaking?

Most of the 2014+ BMWs I've worked on are dry FWIW, it seems like after about 10 years give or take a couple, they just start leaking like crazy.

My brothers E90 had a oil pan gasket leak and oil filter housing as did my BMW X-5 ( E70). On mine I replaced Valve cover gasket, oil plan, oil filter housing. Then all that brittle plastic on the interior and coolant hoses and outlet pipe from the block. They don't age well... Sounds like the new ones are better? there's just something about the 07-13's where they cut corners or the bean counters used the cheapest gaskets and plastics.

That makes sense. My older X3 E89 was bone dry for the most part. Much better built.. Well... Except for the transfercase " worm gear" that broke apart. BMW used plastic on a transfercase drive gear.. That was a real hoot taking it out in pieces. Amazon actually makes a aluminum replacement from China.. The Irony... the Chinese coming to the rescue. No idea why BMW engineers thought was good choice for a X drive AWD system. Planned obsolesce?
