M340i w/ adaptive front suspension noise??!

I have own my car for about half a year now, lately I have noticed front suspension sound going over bump at low speed. Sounds like the top mount isn't tight but which i doubt that is possible. Does anyone share this strange noise with me? Also my alignment is off after 1 month had it redone at the dealership which costed me $200 I am bringing back to the dealer this Friday to have have a final inspection before slapping on the Dinan exhaust so frustrating.

I have had noise coming from front suspension , my car is a 330i without adaptative suspension - the silent blocks were identified as root cause of the problem - silent blocks alone cannot be changed and suspension triangles (inc silent blocks) have been changed - now problem fixed. Done under warranty .
I think if alignment cannot stand more than a month , it's certainly due to a car problem and it should not be redone at your cost . First they should have search why after a month is was off.

Another dealer tried to charge me 249 lol. It sucks as outside shops (called 3) doesn't have alignment update on the newer cars yet as of 5/8/20 so my only shot was to bring back to dealer.

The dealer did the alignment was not able to replicate the sound so they returned my car back to me exactly how it was. I then recorded some vid of the sounds it makes and brought in another dealer on Thursday. They called and told me they were able to replicate the sound after third road test, now they said it'll take them some time to identify the sound and repair it. Finger crossed they will fix it as my Dinan exhaust arrived last week and cannot wait to install it

I know this is an old thread, but were you ever able to get this fixed? I'm having the same issue and can never get it to occur consistently enough when road testing w/ the dealer. Have several videos, but they say this is not enough for them to do anything about it.
