Is the ASD sound on all the time?

Is the fake sound on all the time or only in certain mode like Sport & Sport+
or would it be on in Eco Pro and Comfort mode as well?

If you have a US F3x 3-series you probably don't have an ASD. I wanted to use a bypass harness to get rid of an ASD. My dealer told me my VIN showed my car having an ASD. But I removed the trunk panels on the left side exposing my amplifier. There wasn't one and the H/K amp didn't have the wiring harness to connect one. Technicpnp who make the ASD Bypass harness said that they haven't seen an ASD in a US 3-series but they see them in European 3-Series.

I have a MY19 F36 430i and I can certainly hear it when in Sport and Sport+ mode. There is a distinct rumble when it's turned on. It's quiet in Comfort and EcoPro mode but the engine just sounds too smooth as if it's an inline 6 which it isn't. Did they actually piped in fake 6 cylinder sound or is that the actual sound my car makes?

Yup. you are hearing a prerecorded sound from an I6. When it sounds too good to be true, it generally is.
