Im getting a strange noise when engine is hot on a 2016 G63 AMG with under 10,000 KM on the clock.

It comes on and off only when the engine is reached maximum temperature.

Im attaching a video with the sound, I have uploaded it to dropbox. The sound Im referring to is not the normal fuel injectors pulsing its that wowowow noise that goes on and off.

Its like a wowowo noise.

Only happens after engine has reached maximum temperature.

Any suggestions/recommendations advice would be of maximum help.

Anyone had similar noise?

Thanks a lot in advance.

I don't hear any serious noise

what is the ambient temperature or what cause the engine to operate at the maximum temperature. Is it when you push the car very hard or slow traffic for example?

i hear the noise your talking about now.. its on and off.. sounds like how a fan switches on and off but its more quicker.. maybe you need a new thermostat?

There are L.I. documents pertaining to various engine noises but yours sounds almost like when a pulsation dampener goes bad. I dont believe your G wagon is equipped with that system though, but thats a similar sound. If you pull that front engine cover and shoot me a pic of whats under that cover, I would be able to tell you right away if you have one or not.
