Electronic sound after reversing.

[lasancaya]

This sound started yesterday afer reversing car off drive and continued until switched of engine.
Today no sound until I reversed out of parking space. Sound is very quiet but continuous. A bit like a ringtone.

Any help/suggestions appreciated. Its drving me barmy.

Car is 2018 C Class Estate 250 diesel.

I have attached a recording of sound. File needs downloading and rename to .mp3 extension to play.
Oh file deleted by moderator. If you need to hear it message me please.

You could upload to YouTube and link it back here

Mine also does this, as you get nearer to something, like a tree or a bollard, the bleeping noise gets louder. There is a button to turn it off.

Mine also has it on the front. I am not a huge fan, but it does stop you hitting stuff.

Doh ! Does not get louder, its not parking sensors. Blobcat suggestion works here is the url to YouTube video playing the sound.

No idea what that is, no one’s left any electronic device in the back of the car have they?

Sounds like a dashcam startup noise on repeat. If you have one, I suspect it's dying.

alexanderfoti well done ! Got in car today, started up sound was going off.
Sounded like it was coming from lower dashboard but sure enough it was the nextbase dashcam.
Maybe the subzero temps (-6/8) affected it, anyway its warming up in my kitchen so will test later.

Thanks for the helpful replies. 10/10 for alex.
