Back in 2011, I bought a new MX-5. From new, there was an annoying buzzing sound at 3250 RPM.
I took it back to the dealer a couple of times. They took the dash out, but could find nothing wrong. Eventually I just had to put up with it. But it really took the edge off my otherwise lovely new car.
When the car got to nearly 10 years old, it had the MIL come on. The cause was the EGR actuation valve/motor.
As part of changing the motor, I had to take the strut brace out. When I put it back together, the buzzing had gone.
