Question Asked: A very annoying high pitch sound
July 07, 2009, 10:50 PM
I recently acquired a 330i. Everything is good. Just when it speeds up to 20 mph, I can hear a high pitch sound. It goes to a higher frequency when I push the gas paddle. On freeway, it comes and goes. The noise usually comes back when I starts to accelerate, goes away when gas is let go, and comes back again when accelerating. Please help me! It drives me crazy!
