2012 Mercedes Benz E350 4Matic engine noises when I turn off the car
The car makes this noise and I noticed it just today. I also turned it off one time and didn't hear it but then turned the car off couple times and this noise keeps happening when the car is off and it goes away after 5-25 seconds. Is this normal? If not what is wrong with it?
I never heard this before and it just started today from what I can recall. Car turns on and drives fine and nothing seems wrong accept this noise when the car shuts off.

Haven't heard that but maybe someone will chime in. Can you locate the source of the sound? Can't see anything on the video at that point.

Coming from front engine driver side
Could this be caused electrically? I did have rodent poop and pee in car and I wonder if this could be damaged by the rodents? Or is this normal?

I can't say the sound is normal since I don't notice it. But perhaps someone else had heard that before.
You don't have the led headlights by chance? Those have fans to cool the lights after turning off. Not sure if they sound like that though.

Can you answer the question regarding whether or not you have LED lighting?

if you had electrical issues I would think you'd get signs of that while the car is running, like error messages or certain systems not running properly. Have you had any signs of that? Were there chew marks or other pest damage?

I have the standard lights in the car. I noticed it happens and it doesn't have the boing sound but still does make the noise when I turn off the car. Car runs fine and no service lights but this noise happens when the car shuts off.
i noticed to another sound when I don't drive the car overnight and open the trunk and this thump/thud sound happens then the trunk releasing pressing/holding the trunk release button the key and today when I locked the car the passenger side when locking with my car key I heard a loud "pop"
I wonder if this is all linked to the same issue?
The trunk unlock sound and door lock sounds don't happen all the time but random times too. Is this electrical?

I will say that these W212 and W211 cars are the noisiest cars I have ever owned, especially with Airmatic. Noises come from everywhere and at all times of the day. I have the full LED lighting package and your noise sounds like my cooling fans. If you don't have the LED package, then this is a noise that I am not familiar with. Take it to your dealer or independent shop for further analysis.

My trunk lid does make a pop sound when it is released and springs open. I haven't heard a door lock pop yet although the sound of all 4 doors locking at one time is noticeable (not a pop though).
I agree with Key08 that you should get it checked out. I don't think you're in danger or anything. With no warning lights and no battery drain, I would just until the next service. Keep track of the sounds and take photos or video of the locations if you notice the exact spot.
Also, hopefully your pest problem is gone but be sure to stay on top of that. Don't want to be cruising along and have something skitter across the dash.

Nothing new. They said it could be mechanical but didn't really give me a firm answer.
Below is my lights
