So pretty much this issue has been bugging me for a while now.
It only happens time to time (like literally only sometimes , right now been running fine for like 3-4 days , before that issue was for like 2 days in row) - basically happens once or twice a week (sometimes have gone even week without issue)
Issue : car sounds like a tractor, sounds are fine when revving on spot.

I tried to make a video for sound but you can only hear beginning due wind.

Adding to attachment.



Maybe someone's could assist what could be the issue , not sure if it's turbo or anything else
