AUDI-DECODE-SECRET-PIN

Get your secret PIN and other info from your dump EEPROM file directly, without the need for any hardware or other software etc.

This project is created as part of the effort spent to populate my PIN code from my J518 module. This has been tested on J518 units running several software versions including 3.0 and 3.1, for 2KB EEPROM dumps from Motorola MC9S12 family (e.g., MC9S12DG128).

Features:

• Reads and decodes EEPROM binary dump
• Extracts VIN, PIN, Component Security bytes (CS1/CS2), MACs, Power Class
• Lists up to 4 stored EZS keys and key count
• WOrks on VAG cars between 2004 and 2012 (mostly)

No Need For:

• OBD tools
• Third-party commercial software
• Hardware

For GUI version, we use Python and tkinter to allow drag-n-drop EEPROM decoding across platforms (Linux & Windows), with GitHub Actions pipeline that builds `.exe

For running GUI in linux:

python eeprom.decoder.j518.py
