Hi friends. I can not read this MCU from BMW CAS4. I am use some diagram but not succes. How much i can see i have problem with Reset pin, not have 5V. I have and some VVDI diagram but not try it. If someone succeed to read it with XPROGM please help with diagram and instruction. This diagram not work for me (i did not use 12v than 5v) and after trying CAS work.
Thank you

With this setup you can read and write successfully? What xprog do you use?
