Noise behind dash

ncrypt22 · 11-12-2020, 12:17 PM

Evening, could anyone advise what this whirring kind of sound is and if it's normal?

Seems to mostly happen after adjusting the climate control (even with AC off), but also sometimes just by itself (either engine on or off).

I have a video example here:

Fuel pump?

I've noticed this in mine at times. although the pitch is a little different and not as loud as yours, but that may be the recording itself. I don't think mine lasts that long either.

I have this problem too, but only after I installed the dinan sport tune, don't know how the slight bump in power cause some frequency sync vibration for the dash to make that noise.

Hm, no tuning on mine -yet.

I always thought that was normal, my F30 makes that same exact noise and my B8 A4 used to as well.
