VAG ECU EEPROM Calculator v2 is a specialized and highly effective tool for workshops and technicians who work on Volkswagen Auto Group (VAG) vehicles from the late 1990s to mid-2000s. Its primary purpose is to analyze and automatically patch EEPROM files from the extremely common Bosch EDC15 (Diesel) and ME7 (Gasoline) engine control units. This utility simplifies complex tasks like immobilizer removal and PIN code retrieval into just a few clicks.
Key Functions:
• One-Click Immobilizer Disable (Immo Off): The most powerful feature of this tool. It allows you to permanently disable the factory immobilizer system by automatically patching the EEPROM file. This is an essential function for ECU swaps, or in situations with lost keys where programming is not possible.
• PIN Code / Login Retrieval: Automatically reads and displays the 4-digit Secret Key Code (SKC) or Login PIN from the EEPROM data. This code is required for key programming and other diagnostic procedures.
• Odometer Reading (EDC15): Accurately reads the mileage value stored within the EEPROM of Bosch EDC15 ECUs.
• VIN & Immo Number Display: Clearly shows the Vehicle Identification Number (FIN/VIN) and Immobilizer Number stored in the ECU.
• Basic ME7 Tuning Tweaks: The "Channels" tab for ME7 provides an easy-to-use interface for making simple performance adjustments to parameters like idle speed, fuel enrichment, ignition timing, and more, without needing complex tuning software like WinOLS.
Simple Workflow:
Read the EEPROM data (e.g., 95040, 24c04, etc.) from the ECU using a serial programmer (like XPROG, UPA, etc.).
Load the saved .bin file into the VAG ECU EEPROM Calculator.
The tool will instantly display the SKC/PIN, VIN, and other information.
Click the "Immo Off" button or make other adjustments as needed.
Save the new, modified .bin file.
Write the new file back to the EEPROM chip on the ECU.
System Compatibility
This software has been fully tested and is confirmed to be working perfectly on Windows 10 LTSC (2019).
