WHISTLING NOISE ON RUNDOWN AND AT IDLE

1999 BMW 316

Noises problem
1999 BMW 316 4 cyl Two Wheel Drive Manual 151000 miles

Hi. I am experiencing a high pitched whistle in my 99 E46 BMW 316i 1.9. It happens once the car warms up after 20 miles or so. It disappears if you fully press the accelerator but is louder as the car comes down to idle speed. Already changed the idle regulator at the advice of a shoddy mechanic who lied to me that he had fixed the problem. Please please please help. This noise is ruining my life. My vin is aw52308
