Hey guys. i have a problem here. i went to get my oil changed and after i left about half a mile down i get to a stop light and my cars idle goes down a bit and my car starts to tremble as if its about to shut off, also there is a light whistling sound coming from the engine. when i accelerate to drive off everything goes away, whistling noise and all. when i come to another stop it comes back. but even with all the trembling going on the car never dies out. if i shut the car off and turn it back on, it doesn't happen anymore for a few minutes. this has happened to me once before few months back and i shut the car off turned it back on and the problem never returned till today. anyone here have the same issue and what could be the problem im having. i also posted a video on youtube, you might have to turn up your speakers because the volume is low. you can listen to the whistling noise. ive read that maybe it could be bad injectors? would very much appreciate anyones help. thank you.

My car makes the same noise. I have taken my car into bmw 3x for this and every time I get the same response, "We were not able to replicate the issue"

it comes and goes, it didnt come back today at all. i left it with my mechanic and see what he can come up with. i let him know that my idle was low so maybe that'll give him an idea where it would come from.

Did you ever get an answer?

The dealer finally acknowledged the noise and advised me that it was from my pulley but, they are still checking things out

My mechanic (friend of mine) who works at BMW told me i was having issues with the Vanos Solenoids so make sure you ask your mechanic before he rips you off to check that first. my issue is gone im happy with the work.
