Hi I have a customer who has lost his brakes on his sl500 Mercedes, on checking the vehicle i found that it had a warning sign on the dash and bleeping with the massage vist workshop.
so i checked for dtc and found C26DE, C26BB, C223C, C25D4, C22BC. I cleared the faults and one come back malfunction in pressure supply. what are my options and can the maxisys program a new unit

Thanks mike
