So, I am cautiously optimistic the new part does, in fact, correct the problem.
It also seems to me that the system is louder, i.e., I don't have to have the volume bar as close to max to achieve the desired volume. It always seemed like it needed to be turned up more than on my 2018 540. I have read that the spec for the 2021 reduces the power of the amp from prior levels. Curious if that could have caused the problems many of us have experienced and if the new amp is putting out the prior power level.

Is this applicable for the cars build in Mexico?? because even my car has same issue, built in Oct 2020. |
My car having same issues, also mexico build from October.
Brought in to service and referenced the PUMA number here, was told they can't replace based off that and there was nothing in their tech database officially from BMW.
Was told they won't replace the amp and they couldn't replicate the issue.
Since it is very sporadic when it occurs, I'm not sure how to change their opinion and get a replacement.
