Dear all

I have a MB S550 2015, Japanese imported.

From time to time, the car makes a very strong beep while parked. Please see the video uploaded in the link below.

Can anyone help ?

Can't find the attachment... Is the car in gear when you say it is parked?

I have never heard anything like that before coming from a MB. Sounds like a reverse warning beep that a large truck makes.

I have updated the post.you can now see the video.

the car makes this sound after parking it. Engine off.

I think I see and hear what it is. It is a proximity sensor that deters anyone from getting near the car when it is locked. The mirrors are folded back indicating the car is locked and I keep seeing a small blue light flashing on the dash in the dead center at the bottom of the windshield. Walk away from the car and it will probably stop. Previous owner must have had it installed.

Not really.
The car does not beep when someone is nearby.

I have noticed the blue light flashing .. that device has got another device installed next to it which I think is related to the ETC toll gate system in Japan.

Then take it to a dealership service department.

This is the device that is flashing blue.



is this installed in all 2015 s550 or an accessory ?
what is it for?
