VAG MEDC17 ECUS - StefanDST - 08-20-2026

Main Features:
  • Support for modules with Immo 4 and Immo 5 , 6 and 6 SHE.
  • Editing all immobilizer data stored in the EEPROM Immo 4 and Immo 5 , 6 for immo 6 SHE only vin mac powerclass and immo off available.
  • Disabling the immobilizer and changing its status on Immo 4 ,5 ,6 , 6 SHE modules.
  • Changing the immobilizer status on Immo 4 5 6 6 SHE modules.
Working with the Module

To begin, load the flash and EEPROM files .
During loading, the file sizes are checked to ensure they are valid. 
After the data has been loaded successfully, you can begin working with the immobilizer data.
For Immo 4 modules, the following data can be modified: Fazit, VIN, Immo ID, CS, MAC, PIN, and immobilizer status. The following statuses are available:
  • Not Learned
  • Learned
  • Immo Off
For Immo 5 ,6  modules, the following data can be modified: Fazit, VIN, CS, MAC, PowerClass, and immobilizer status. The following statuses are available:
  • Not Learned
  • Learned
  • Bad Learned
Immobilizer data can be edited manually or by copying values into the corresponding fields.
After making the required changes, save the data by clicking the “Save Files” button. The entered data is validated before it is saved.
Important Notes:
To process the immobilizer data correctly, the flash and EEPROM files must come from the same ECU. Using files from different ECUs will result in incorrect data decryption.
When changing the PowerClass, remember that this value is also stored in the flash memory. If the PowerClass values in the EEPROM and flash do not match, the ECU will fail immobilizer authorization. The value can be checked and modified using a separate module  .
