Sometime earlier this year I noticed light gray exhaust smoke on starting my 2024 4BW after three or more days of being parked, pretty good telltale for an oil leak somewhere. I suspected turbo shaft seals or valve stem seals. Turns out it was the R/H turbo leaking. I'm getting a new one under warranty at 6,000 miles. Just wondering if anyone else has experienced this or is mine (hopefully) a fluke.
 
ouch...
 
That's not common at all. The factory turbos on these engines are excellent.
