Here the pinout to read this bcm2 of Audi A5 70F3380 in xhorse vvdi prog programmer.
Make sure you choose correct MCU.
I read one of these a few days ago. Don’t remove any components from the board and the connection is same as picture. The board does look slightly different from vvdi picture. I think all useful data will be inside the 95320.
Vvdi prog not have SPI, only UART, other programmers have.
Good luck!
