Hi all,

 

when i turn my car off and the engine stops, a couple of seconds afterwards a distinct squeak seems to come from the engine bay. 

 

It sounds like its a pulley or such stopping. Any ideas? i will try and get a video recording of it this evening.

 

thanks

 

Is it like a electronic squeak? 

Like a buzz? Most cars do this as it’s the electrical system turning off and also I believe the system is given a charge of current to give it a clean of sorts? No 100% on this but it’s my theory 

Hi please see video attached. Not sure if it's the electronic noise you are talking about 

 

 

Normal, vacuum control unit closing.
