It’s either coolant or oil. What does the fluid smell like when you wipe some with your fiber and smell it? Is it dripping on the driveway/garage floor?

definitley oil. Reason i found out is the “check oil level next refueling” popped up that made me look around. Very scant drippage in the driveway, undercarriage cover is catching it so far.

Not uncommon. Try the search feature - turbo oil leaks on M278 and M157 are posted on this site. A V8 owner will be along soon with more input.

Well finally able to look under and this is what I saw. Looking at passenger side turbo bottom part. Hoping its just a simple o-ring replacement and not the whole turbo assembly itself

Yep, seems to be a fair sized leak. Try the search feature. Turbo oil lines seem to come up now and then for the M278 engine on this site.
