Video: Weird Whirring/low Siren sounds at low rpms
I’m getting a weird whirring/siren like sound when accelerating. I can hear it only in low rpms and when I’m going fairly slow speeds. My engine is stock and my mods include a cat back exhaust, aftermarket wheels and coilovers.
Here’s a clip. Kind of hard to hear but it’s the low pitched whir or hum. Not sure if it’s from the drive train or engine bay. Need some input! |

Mine makes a low pitched drone when I'm moving slowly. The source of the noise is probably the differential and I'm told it's normal for this car.

Hmm someone on a Facebook group just mentioned that it may be an exhaust cam bearing. Can anyone corroborate that statement? Very interesting.

By George, I think you’re right. I changed my diff fluid thinking it was my diff but the sound persisted. Then I noticed that it’s more prevalent in sport+ than in efficient. Also the sound is there when revving in neutral. It’s mainky between 1.5k to 2.5k rpm as well.
Is this normal? Doesn’t seem so. I wonder if my turbos are going bad? |
