hear of a faint siren sound
2015 E Class AMG when switched off not always even if I open a door 0r I just came in from a run I hear like a faint siren noise coming from the engine compartment, I know that it is not something is wrong but would love to know what it is. Thank you.

Could be water pump cycling fluid after car is shut off, Can also be the headlight cooling fans running to cool down the led lights until the car is locked.

Hahaha this is so hilarious! Yeah that air suspension sound really like farts… I also hear all kinds of noises. I’m thinking the siren might be some fan noise.
