I went to the dealer and ride togher with an technican, unfortunately we had trouble finding a "perfect" speed bump to test on. We drove around for 15 minutes on diffrent type of bumpy roads, but it was hard to re-create the clunk sound. So he didn't think it was any problem with the car or suspension and this was normal behavior. However he told me that my car needed 3 major ECU(?) updates and one of the updates was for driving assistane or something like that, the other two updates didn't he have any information about. So I let them update the car, took around 3-4 hours. When I finally drove away, I tested the "perfect" speed bump near my house and no "clunk" sound! Drove past it several times to make sure, and in higher speed, no problem, just simple smooth suspenion!

The software of my iDrive was 07.2018 before the update, now it's 03.2020. But as someone said ealier in this thread, the FW for the ECU/control blocks are something else.
