Your exhaust! LolHi, just bought a JT Ecodiesel.
Frind of mine told me, Jeep makes hissing sound on right rear end when idling. checked out myself: correct, like hissing air. what is this? diesel pump? AC Converter?
thx
That makes sense! Thank you very much!It's likely the wastegate releasing unused pressurized air from the turbo. Haven't noticed it on mine but that would be my first thought.
Other than that it could be something with the emissions considering there is recirculating gasses that help reduce NOx.
All just speculation though, I'll take a listen the next time I start mine up.
