Weird digital chirping sound after starting car randomly
So just like in this video, I get this strange sound. It usually happens in the morning, but sometimes after getting out of the grocery store or something short like that. https://www.youtube.com/shorts/FOTbTSp7DcY
What the heck is it, am I screwed? |

Hello
I don't know for sure what your problem is but I've tried listening multiple times. I noticed the idle goes down (at I'm guessing normal idle RPM, coming down from its "cold start" RPM) at the same time this sound appears. Thus I feel like this is more of a valve closing or opening that's making this sound, maybe it's on its way out or maybe it needs lubrication it doesn't have, I'm not sure. If it is a valve, I don't know your engine but it might be a secondary air pump, a idle valve or something Good luck with it |

It is exhaust flap! 😂 my friend have same issue for few days, today we found out it is exhaust flap 😆 we'll try to grease it or something, to make that sound go away.
