Yesterday i was coming back home from mountains and after the highway i slowed down because of the highway payment:i was in 5th, passed in 4th, then in 3th , in 2nd and then i pressed the clutch and the brakes both and...the engine stopped!!!!
My doubt is: did this engine stop damage turbo system?
The car run as usual.
But how can i know if turbo is ok?
Any opinions and suggestions are WELCOME !
Thanks Mates.
