BMW Germany has a TSB saying that when a M240i G42 is noisy in the rear on bad roads to replace the shock absorbers, and if that doesn't help to open a TSARA case. This was formerly known as a PuMA case.

As a lot of people found out replacing the shock absorbers does nothing, and BMW then tells the dealer to put in a different shock absorber bearing/mount from a 3 series: 33 50 6 889 267
This seems to fix the noise, a lot of people in a German forum wrote that this fixed the noise completely. Some had both shock absorbers and mounts replaced, others only the mounts and it seems to work.

Interesting news. I wonder if we can get the TSB number. I imagine that would be a helpful reference when contacting a US dealer and discussing this work.

This is a helpful and promising post, thank you.

These mounts are pretty inexpensive, and I am more prone to just purchase them and install myself. I think I could install these parts in 3-4 hours, which is at least as much time as I would spend working with the dealer to do it... and the $200 in parts to not have to worry about them driving or damaging my car isn't a bad compromise.

My concern with attempting this potential resolution is that Tegs200 eliminated the sound by installing Bilstein replacement shocks, which photos do not show including a replacement for this mount... so if the problem was the mount, I would not expect the shock replacement to have resolved the noise in his car.

Unless the issue was due to a poor interface of the combination of original shock and mount together.
