BMW F10 523i 2010 CAS4 error 0x930725 Comfort Start Line A_S_START: Short Circuit
Hello,


 BMW 523i F10 from 2010. 

Since today, I have an error in the CAS4:

0x930725 Comfort Start Line A_S_START: Short Circuit to Ground 


After clearing it, it keeps reappearing...

 I googled the error, but found nothing...

 Can anyone interpret this error? 

What is the Comfort Start Line A_S_START? 


cas4 defective ?

Has anybody solution for this failure ?

Best Regards
