Hello, I notice wierd sound after unlock car like a whistle, its about 1 sec after I ulock car, but only when car been locked for some long time, I suggest that after car go “deep sleep”, previously I dont notice that sound, so want to ask what it can be, or maybe its normal and I just dont pay attention before

Unless I am not hearing the correct sound, mine makes that same sound every time I unlock it. It is both outside mirrors folding outwards.

 

I upload more video to YouTube, you also have like this sound that is after unlock can? I mean not mirrors, but a “whistle” like sound? its only appear when car is locked long, like a every morning first unlock, then when I lock/unlock there is no this sound

 

Your 3 videos sound perfectly normal to me.

 

I don't think I've ever heard that, but will have to listen next time I unlock in the morning. Interesting.

 

Fuel pump priming?

 

Do you manage to try? Very interesting

 

UPDATE

This sound make me crazy, still not go to dealer, but find out that this sound came somewhere near fuel door/rear right door but somewhere like below fuel door.

Its only appear when I came on morning to car, maybe its somehow connected that now here is cold winter... But car in closed parking. So car make this sound at morning then all day with short/mid staying locked there is no that sound. But I also hear one/two times this sound but not as loud and not as fast like on videos when car was stay locked long, but not all night. DD

Very odd thing for me

 

Bump, still don’t understand this sound is ok or not, can someone confirm that have this sound?

 

i got the same sound. must be normal. you unlock the car or open the door in the morning. it must be doing something real....

 

I don't know what the high pitched squeak sound is but my 2019 550 did this and so does my 2021 G-63. I'm sure its normal as its something activating.

 

Fuel pump priming

 

Thank you very much for answers, I already also think its ok, but dealer even dont understand what sound I mean, so I make new one without mirror close open enabled.


onlu strange why I don’t mention it before...
