VAG EDC15 Immobilizer Utility is a compact tool for Bosch EDC15 ECUs used in VAG vehicles. It reads login PIN from EEPROM dumps, verifies or recalculates checksum and allows safe immobilizer state switching for ECU bench testing and replacement scenarios.
Highlights
- Reads VIN, immobilizer ID and stored mileage from EDC15 EEPROM
- Displays and extracts login PIN for service operations
- Checksum calculation to validate edited dumps
- Immo On / Immo Off switching for controlled test environments
- Load and save BIN files with quick presets
- Clean GUI by VAGdashCOM for fast workflow
Package contents
- EDC15Calc V1.0.0.0 (application)
Compatibility notes
Intended for Bosch EDC15 ECUs in VAG platforms. Functions depend on ECU variant and EEPROM content quality. Use only for diagnostics, ECU cloning or replacement where permitted. Vehicle behavior and immobilizer policies vary by market and model year.
Basic usage
- Open the EEPROM BIN and review VIN, Immo ID and mileage
- Use “Calc CheckSumm” after any change to validate the file
- Apply Immo On/Off only for bench tests and documented ECU service
- Save backups of all original files before writing to any ECU
Operating systems
- Windows and macOS (via virtualization) with a compatible EEPROM read/write setup
Minimum system requirements
