Question:
How can we read with Opel Astra BCM D70F3469 with xhorse vvdi prog? Follow the wiring diagram but it failed to read.
Solution:
That mcu is protected, can’t read by vvdi prog. only write.
immo data is on EPROM 95160 , but all configurations on Mcu , full clone only with i/o terminal.
if you only clone the eeprom then the car will start. but if there is a different software and configuration in the used one, something will not work correctly, for example, lights or something else, just like if you had an automatic gearbox and you buy a module from a manual one, it will also be bad.
