Electric Frequency Noise

[viven]

Hi,

I recently been experiencing a high pitched electric frequency noise in the car and have no idea where it is coming from. I been experiencing it even when the radio and aircon is off.

Not sure if it is just a coincidence but I I only noticed it since I fitted a BMW Performance exhaust on the car. Strangely, it is only in the car though.

Any ideas where to look? The dealership has no idea where to begin.

Thanks,
Viven

hi I've got the same issue, i've done the Performance exhaust, but i've blocked the vacuum line. the issue started pretty recently so i guess the vacuum line may be perishing

just my 2 cents

Thanks guys. Will let you know if it resolves the issue

If it's from the dashboard I assume it's an electronic sort of sound? I had a similar issue and figured out it was coming from an old tracker unit installed in the vehicle.
