Help! Engine buzz noise at 60 MPH 2018 AUDI A3 1.5 tfsi

[shaza]

Hello can somebody please help. I would greatly appreciate it.

 

When I drive my Audi A3 at exact 60 mph, I hear a buzzing noise coming from the engine. The noise is to the effect of a mobile phone vibrating when on silent and lost behind a sofa..

 

The buzz

 

 

The buzzing starts stops, then starts for a little longer and then stops, at various lengths of time.

 

It only happens at 60 mph, not at any higher speed or any less speed which makes it really bizarre.

 

I have recently tracked the car and wheel balanced it. Changed all 4 tyres.

Its definitely a noise coming from the engine area from the drivers side.

 

I have attached a video of the noise so you can hear it. If you listen carefully and ignore the typical road noise, you can hear it

 

Any help would be really appreciated.

 

Thank you
