Xhorse VVDI BIMTool Cannot Update CAS3+ ISTAP Firmware via OBD Solution

  Problem: It is a BMW CAS3+ ISTAP. I was trying to get the ISN from the DME but I got a fail to connect message (Current CAS can’t update firmware via OBD). however, the  Xhorse VVDI BIMTool Pro  can successfully read the DME information. I have another question, for DME/CAS what would be the ideal specs of a power supply? Volts/Amps. for bench test and coding. Solution: You will need 12V 3A power supply.   If CAS3 is ISTAP version, there will prompt update CAS flash when the first time read key info (see image below). Upgrade CAS flash only need 10 minutes, after update flash turn to next step. If the update CAS failed for some reasons, you can fix it with the function in  Menu->Special Function->CAS Repair (EEPROM OBDII) , choose type“ OBDII-CAS3+ISTAP Version ” , CAS Repair with OBD ->Enter CAS ID to repair. If with  Xhorse CAS Plug , follow instruction here How to Repair BMW CAS3++ with Xhorse VVDI BIMTool Pro & CAS Plug?
