I'm quite annoyed by this. I recently sent my Mavic 2 Pro to be repaired because one of the front indicator LED lights stopped working (never crashed just stopped turning on). I was told that the repair would be free as it was still covered by warranty, however when I finally got my drone back I realised they had sent a completely different one back (different serial number). I contacted DJI about this and was told that was normal, and from what I could tell it was brand new.

However, starting up my replacement Mavic it makes the sounds you can hear in the video! Has anyone seen this before? I don't know why my other drone, which was fine apart from the light, wasn't just repaired and returned. Now I have another faulty drone!

Anyone have any ideas on what would cause this noise? The drones firmware is fully updated. I'm really not happy with the QC DJI seems to run on their products. Following my repair case it said they checked the drone was fucntioning correctly, I guess not?

I’m a “glass half full” kind of guy, I think it sounds pretty cool?

Maybe you could buy Roamingskies a new M2 in exchange for his "pretty cool" sounding M2?
