Everytime I shut the engine off, there is some sort of grinding sound that is real quick coming from the back of the car. My car is completely stock aside from BMC filter. its an '07 with 22k miles. I will get a video clip soon. It doesn't bother me but I was just wondering if this was normal, or if anybody else has encountered this?

 

Eek. Sounds like it would bother me. Sound clip/vid please.

 

same noise for me, I don't worry about it

 

You must have a 6sp car? Maybe a dual mass flywheel you hear.

 

Forgot to mention that the car is a tip

 

Nobody else besides Bob have this problem?

 

My car does it, but it's a 6spd. My old M3 and Z06 did it too, it's the clutch/flywheel. If I clutch in while shutting off it doesn't do it. Not sure about the TIP though.

 

my car does it too, I have a manual.

It almost sounds like a fuel heater from a diesel, but it's not diesel. I've never thought anything of it, but would be interesting to know what it is.

 

My car does it, I wondered the same thing about the sound??? Let us know what you find....

 

My car does it, I have a manual.

 

On a 6speed, I would expect it to do it. On a tip - it's kinda odd. I will try to get a video by Sat.

 

Hey whats up Nico mine does this too! i 'am almost used to it now but it sure sounds wrong i just figured it must me normal & maybe it is if everyone 's hearing the same thing .It's a real quick grinding noise right ,maybe a sec in my case.

 

Hows its going Adam? Yeah it must be normal if others are encountering it. Yeah it really is quick, only like a second like you said.

 

I think I know what you are talking about. It's like a 1/4 second noise that isn't necessarily a grinding noise, but a mechanical noise as if a valve or solenoid is moving. Unfortunately. I have no idea what it is.
