brand new C400X - stalls

the engine is totally controlled digitally and the dealer cannot raise or alter anything. there has to be an update to the engine ECM. This is BMW's totally digitally controlled engine.. the 650 doesn't even have this.

What is your firmware ? Mine was updated last week 021-004-040 i know the latest one is close to this version. They seem to vary depending on location.
yet to see if mine stalls after the update. So far all seems the same (i was on 001 version)
