Everytime I shut the car off I get a funny noise coming from the engine bay. Sounds like thrrrrrr, if you can sound that out. It only happens after the engine is shut off. Any ideas.

 

man you are going to need to elaborate on that one, or make a wav file of it...

 

Definitely have to elaborate on that one.. There are some motors and solenoids that continue to run or move for a short period of time after shutting off the engine. I noticed that the car retains power for about 15 seconds after shutting off the engine and removing the key. (noticed it because my S-AFC doesnt power down immediately when I shut the car off)

 

I'm not sure but it may be the turbo coming to a stop after the engine has stoped.

 

I thought about that too.. Its possible, I don't recall ever hearing mine though.. do you?

 

I think I know what your talking about, its the big fan sitting in front of the radiator. If you stand in front of the car(while its running) you can hear it turn on and off at different intervals, your just turning the car off while its spinning and it makes that noise while its turning off.

 

I dont think its the fan. Maybe the turbo. I'll record it with my digicam. Someone else must have noticed something. By the way my car is stock. Thanks for the help so far.

 

I know what you're talking about I think...I don't think its anything to worry about

 

I think everyone needs to listen carefully when they shut off there cars. Thanks

 

I know what you are talking about. It is the IAC valve (Idle air control) resetting itsef everytime you turn off the car. it sounds almost like a fast clicking sound. nothing to worry about.

 

i think i know that noise, i only hear it when i shut the car off imediatly after driving, if i wait for 2 min for cool down i dont hear it.
