Noob needing help!!!!!!

Same problem here! Started about a week ago. After car sat for an hour or two it would start but with bad “misfire” feel. But ran great with good power after warming up. Then two nights after stopping by a friends house it wouldn’t start at all. Just cranks over. Now I need to also add that I too started getting puffs of white clouds accompanied by strong diesel smell. Once even through my ac vents. And car has slight chatter... almost like a lifter tick? Seems to get louder with different types of different fuels I run. (Usually a BP bio blend) I absolutely love this car. Please Help!!! 2005 Passat 2.0 TDI. AT with 149k miles.

What's the computer saying for codes?

Hey thanks for your reply. There is currently no check engine light coming on for this issue.

"burn your money' wants you to read your computer with a vag-com, something should be stored in your ECU
