Broad support for VAG models from 1997 to roughly 2003 (e.g., Golf Mk4, Passat B5, Octavia A4). Core Functionalities EEPROM Operations:
Select the specific module (e.g., RB4 for certain Audi/VW clusters) from the dropdown and click the desired action like "Read Login Code" or "Write New Mileage". Verification:
The VAG EEPROM Programmer 120 offers a range of features that make it an essential tool for any serious car enthusiast or mechanic. Some of the key features include:
Used to remove the immobilizer functionality (useful in engine swaps).
Excellent for direct reading of MCU or EEPROM chips via soldering.
Extracts the security secret login PIN from instrument clusters (dashboards) and Engine Control Units (ECUs). This PIN is mandatory for programming new keys via tools like VCDS.
Unlike VCDS (VAG-COM), which reads OBD data, the EEPROM Programmer reads the raw memory—the EEPROM chip—within the dashboard. This allows users to view and modify "hidden" data that standard diagnostic tools cannot reach. Key Capabilities and Features
The software does not work with standard ELM327 Bluetooth adapters. It strictly requires a featuring the FTDI FT232 series chip . Cables marketed as "VAG-COM 409.1 KKL" are typically the most compatible and affordable options. 2. Driver Configuration
Select your specific cluster manufacturer type (typically or Motometer for older K-line vehicles). Click on Read EEPROM .
Correcting odometer displays after replacing a damaged instrument cluster to ensure the mileage matches the vehicle's actual history.
