So I hear some kind of buzzer, which comes from the passenger's side of the dashboard. It's directly related to the engine RPM.

So is this some kind of buzzer so I can hear how much RPM my engine is running, or is there something wrong? It sounds like a very tiny turbine in a high-pitched tone.

I'll see if I can make a video tomorrow.

 

it's let you know you should shift to the next gear, as you are approaching the upper RPM limit.

 

^^ not the rev limiter

He's probably talking about coolant induced MIAC

 

It's either MIAC or just the transmission. Mine sounds abit like a turbine especially when engine braking, the transmissions in these cars are super noisy.

It will be easier to tell with a video.

 

What RPM do you hear it at?

 

I hear it in all the RPM's, and it sounds as if it comes from the glovebox, which indicates a MIAC. But it sounds rather like a turbine or a very small fan running at ridiculously high rpm's. It reminds me of something between a turbine and a dentist drill.

I will get the video tomorrow.

 

Try turning the ac off for several miniutes and see if it goes away.

 

It could also be something Grounding out. Many call it alternator whine.
