Gear oil smell inside

[Ducati1098]

Do you happen to have a mishimoto catch can installed? If so, that's your smell issue. I have one installed and vapors will permeate the rubber hose and cause the issue since the can is located near the air inlet for the dash. Relocating the can will help.

Interesting.. I've had their catch cans on for probably 30k miles now and never smelled anything out of the ordinary

Front diff pinion seals are known for failing.

2023 Blk Diamond. 2.7 SAS… no drips on garage floor, no obvious signs of leaks underneath… its a very distinctive odor,,,cabin filter new, any thoughts?

Yup. I've been getting the same gear oil smell from my 24 Big Bend. I do all of my own maintenance and have checked for leaks every time, none found. No TSB's or SSM's on FMCDEALER either. I only smell it when the weather is warmer and only after using 4wd, haven't smelled it at all in winter, so I'm chalking it up to be normal venting from the front axle vent tube. That's really the only conclusion that I have at the moment.
