They actually blamed it on the transmission.

They just upgraded my car to the latest program, and now I hear the low tone whirrrr of the turbos under moderate acceleration. Never ever noticed it before. I have only noticed it when the car is cold and the radio is off.

As opposed to a siren-like high pitch sound? |

It is quite audible when the car is just started, but after a little while it goes away. After a hard thrashing at the drag strip this past weekend, the sound is louder now, but the car still pulls like a bat out of hell, no problems.

Funny thing with mine is that if I beat on the car and get it nice and warm.....the siren noise almost disappears entirely for the duration of the drive.
