NHTSA's summary
The software update improves functions of numerous control units, most importantly the telematics control unit, drivers assistance camera and head unit. The software update improves the following: Check Contol message "Emergency call system failure". However, the emergency call function itself is not affected. The High-beam Assistant reacts too sensitively to oncoming light sources. Individual language packages in the vehicle are erroneously deleted. Prevents unwarranted Check Control messages. Overall theses faults can lead to uncertainty for the customer, but are not relevant to safety or model certification.
