2015 RAM 1500 EcoDiesel has smell in cab coming from motor

[SirGeek2u]

I have this smell coming thru my A/C Vents, smells like engine cleaning fluid but its not. When you open the hood, you can smell it in the back passenger side of the motor (See pic with red circle). Took lots of pics, nothing on th motor but sure does smell. Any clues?

There's a flex pipe that's on the exhaust to the turbo that has been be reported that it cracked. It's sorta rare but it happens.
It's possible the truck may still be under the AEM extended warranty.
