WHY SAFE ERROR ON DASH AFTER IMMO OFF? There may be more than one reason why the "SAFE" message appears on the screen after the immo off process in VAG group vehicles. But usually the main reason comes from communication failure between BCM or DASH and the KEY. The reason for the error messages on the screen is 99% not caused by the ECU If you do not want to receive such messages on the screen, you will need to add a key to BCM or DASH or repair bcm/dash to key communication This message may also appear in some cases with incompatible engine ECU type. This can also happen if only flash immo-off is done on old type VAG ECUs. In these type of ECUs, you can only perform immo-off from EPROM. The same applies to PSA and other brand vehicles. WHAT IS THE MCU ID ? Some new type immo off operations need MCU ID You can see the mcu id information on the main screen or in the file name while reading the ECU with the flasher. It can be like 400XXX ...0000, usually consisting of 16 or 32 characters.This information is also encrypted in the files Some devices show the MCU id information incorrectly. In this case, the immo off file does not work in the vehicle. It closes the ECU communication. HOW SHOULD READ 93Cxx 16bit or 8bit? Read/write as 16 bit The pin 6 (ORG) is connected to pin 8 (VCC) or The pin 6 (ORG) is left unconnected. Read/write as 8 bit if: The pin 6 (ORG) is connected to pin 5 (GND)
