I would like to ask , Benz W164 Diesel, SRS system shows code 9013 91B4 9600. I can't delete the code. Then the Autel device told me to update. So I updated the SRS system. And now the old code is gone but the new code has come up instead : 91B7 90E3 90F3 9600. I deleted the code but it didn't work. I tried coding in expert coding mode but it didn't work. How should I solve this problem?
