Transfer case leak?

insanesam · 08-29-2019, 06:51 PM

Hi All

I have a 2012 BMW X6 M50D with 50000km on it. Recently noticed some oily residue on the cross member holding up the transfer case. The residue did not have any smell to it. Upon closer inspection the transfer case was bone dry (I especially checked around the shaft seals, actuator motor and fill plug). I wiped the the cross member with brake clean. A week later the residue came back and I checked the transfer case again which was bone dry. Picture attached. Anyone can explain where this residue is coming from or what it is?

Thanks,

Hey OP,

Did you find out where the oil leak was coming from? I have the same issue with mine. Thanks.
