The TCB Module and Antenna failed due to a water leak through the sealed roof mounted "Shark Fin" Antenna on top of my vehicle. The vehicle is not completely safe to drive due to the failure of the TCB Module in which the Module activates the "Intelligent Emergency Call" in the case of an accident. Crash and airbag sensors activate an emergency call to the BMW call center in the process, a set of relevant data such as how many passengers and their presumed condition or injury as well as the exact position of the my vehicle is sent automatically to the BMW call center and the nearest emergency service provider. The problem has been inspected and confirmed by my local BMW dealer. There is a warning on my odometer that states "Emergency call system not available."
