Hi, thanks for the heads up. But I dont think its that simple.
CIC has been replaced, TCU, antennas, and a whole lot of modules swapped and changed - still the same.
It is inteference and happens near cell towers or high tension cable.
Service centre know how to reproduce it already ( drive around, park, turn off engine, wait a few seconds , audio cut)
Apparently it is not isolated, it happens on a few other F10, and even their demo car.
BMW Malaysia is working hard on it - and I hope to hear a solution next week.
