Whistle sound while accelerating
Hi guys,
I have been hearing a whistling sound while accelerateing. This mainly happens in fourth gear under 4k rpm. It almost sound like a wire ground issues. Any thoughts? And no I don't have a super charger before you jokers chime in. |

Does it sound like its coming from the rear of the car, drivetrain/differential etc.
Or from engine bay/intake?

What gear and rpm do you notice it? I mainly notice it in 4th through 6th gear under 4K rpm. It also depends on my throttle position, and if I coast I don't hear it. |

I have a faint whistle as well...around 2-4K rpms, I thought it was my actuators because noise started before one of them died, but after getting it fixed theres still a faint whistle...i just assume its normal as the car gets older. How many miles does your M have? im at 36K

I installed an active autowerke filter last week and I'm getting a whistle too, at low rpms 1500-2500. This definitely started right after I installed it. Is this normal? At first I thought it was but now I'm thinking there may be something going on. I made sure that the air filter didn't have any gaps, now I'm thinking it may have moved or maybe it's normal?
