I,ve got bm3 on my 435 and disabled active sound but I’m pretty sure I still hear it. It kinda sounds like an electronic gurgling sound coming from the back speakers. How can I very if this the cause and stop it? It’s killing the driving experience.

From my understanding, disabling ASD from BM3 config menu will disable burbles as well. I would try coding ASD off with Bimmercode (or any other coding devices) first before messing with BM3.

Also coding ASD off is a proven way of doing it

If you want to physically eliminate the ASD then get a bypass harness from Technicpnp. About $55

Make sure that you actually have an ASD. My VIN said that I did but I could not find it. Supposed to be near the H/K amp. Technicpnp told me that they have not seen a US 3-series have an ASD.

Whoops it was disabled in bimmercode. I’ll check to make sure it is still coded out.

So I checked bimmercode and it is turned off. Not sure what is going on but I have about 600 lbs of tile in the trunk with the seats folded down and I heard a strange fake motor sound coming from the rear speakers. The strange part is with the car loaded down it was more prevalent. Just about any throttle input would create the sound. Without the car loaded It would only happen when accelerating fast past 5k rpms.
