Hi there

Ive notices almost like a hiss, pressure release type noise, almost like a mini-dump valve 'puutuuuuuuu' noise after i turn the engine off, after about a second. Could you tell me exactly what it is?

fuel pressure?

cheers

do you have an intake thats probably what it is

 

My 04 used to do that...sounded like throttle body to me. Put the hood up and have someone turn the car off while you are standing beside the engine bay. My 07HR doesn't do it.

 

Mine does it; it's normal. I think it's just the vacuum system equalizing pressure with atmosphere after the engine shuts off.

 

+1 to all the above. Its normal.
