CAS2 to CAS3 Converter v1.2 - The Ultimate Upgrade Utility
Introducing the CAS2 to CAS3 Converter v1.2, a free and powerful software utility designed to make upgrading your BMW's immobilizer system simple and efficient. This tool allows you to convert the data from an older CAS2 module to a format that can be written directly to a newer CAS3 or CAS3+ (C4 Index) module.
This is the perfect solution for technicians replacing a faulty CAS2 unit or performing a vehicle retrofit.
Core Conversion Features
This converter offers two distinct upgrade paths:
Key Functionality
Crucial Final Step (Mandatory After Installation)
After you have written the converted file to your new CAS3/3+ module and installed it in the vehicle, you MUST perform the final coding steps to ensure full functionality. As the software reminds you:
This means you need to use coding software (like NCS-Expert) to:
Hardware & System Information
Prerequisites:
To use this software, you first need to read the EEPROM dump from your original CAS2 module. This requires a compatible hardware programmer (e.g., XPROG-M, UPA-S, Rosfar).
System Requirements:
Disclaimer
This is an expert-level tool. An incorrect module upgrade process can render a vehicle immobile. The user must understand the full procedure, including the mandatory final coding step. The user is fully responsible for all actions performed with this software.

This is the perfect solution for technicians replacing a faulty CAS2 unit or performing a vehicle retrofit.
Core Conversion Features
This converter offers two distinct upgrade paths:
- CAS2 to CAS3 (C3 Index): Converts an eeprom dump from a CAS2 module (typically with a 2K79X processor) into a file ready to be programmed into a standard CAS3 module (typically with a 0L01Y processor).
- CAS2/CAS3 C3 to CAS3+ (C4 Index): This advanced function automatically generates a compatible file for the newest CAS3+ modules. As the software notes, "No need CAS3++ eeprom file. Its will automatic create for you!".
Key Functionality
- Full Data Transfer: The software automatically and accurately transfers all critical data from your old module to the new file, including: VIN, Mileage, Power Class, all stored Key Information, and Key Frequency.
- Built-in ELV OFF Function: Includes a dedicated "ELV off Flash save" button. This allows you to create a converted file with the Electronic Steering Lock (ELV) already disabled, which is incredibly useful for preventing future ELV failures.
- Simple Workflow: The process is straightforward: open your original CAS2 eeprom dump, select the desired conversion type, and click "Convert and save". The software shows the progress and notifies you upon completion.
Crucial Final Step (Mandatory After Installation)
After you have written the converted file to your new CAS3/3+ module and installed it in the vehicle, you MUST perform the final coding steps to ensure full functionality. As the software reminds you:
This means you need to use coding software (like NCS-Expert) to:
- Copy the Vehicle Order (FA) from the Light Module (LM) or Footwell Module (FRM) to your new CAS module.
- Perform a default coding of the CAS module so it learns the car's specific configuration.
Hardware & System Information
Prerequisites:
To use this software, you first need to read the EEPROM dump from your original CAS2 module. This requires a compatible hardware programmer (e.g., XPROG-M, UPA-S, Rosfar).
System Requirements:
- Operating System: This software was tested on Windows 10 Enterprise LTSC (2019) and should be compatible with other recent Windows versions.
