CAS3++ Editor v1.2 - Advanced Repair & Recovery Tool
Introducing the CAS3++ Editor v1.2, a free and highly advanced software utility designed for automotive professionals and security experts. This tool goes beyond simple data editing, offering powerful functions to repair, recover, and extract critical data from complex and encrypted BMW CAS3+ and CAS3++ immobilizer systems.
This is the go-to solution for many "last resort" scenarios where other tools fail.
Advanced Repair & Recovery Functions
Before using this tool, it's critical to understand which version of the CAS3 module you are working on.
To read the required 4KB EEPROM dump from the CAS3+ module (MC9S12XDP512), you will need a reliable hardware programmer. Commonly used tools include:

Advanced Repair & Recovery Functions
- Repair CAS3+: A crucial function designed to recover modules that have been "bricked" or are unresponsive after a failed firmware downgrade. (Note: This function is powerful but comes with a "Not 100% guaranteed!!!" warning).
- Repair CAS3+ ISN: For situations where the ISN is unknown and encrypted within the module. This feature attempts to decrypt the stored Secret Key (SK) to reveal the ISN. (Note: This function is also "Not 100% guaranteed!!!").
- All Keys Lost Solution (EDC16): A dedicated function to create a working key file when all keys are lost on E60, E70, and E71 models equipped with an EDC16 DME.
- Crypto OFF Save Mode: Allows you to save the EEPROM file with the EWS4 crypto-sync disabled.
- EGS + DME Sync: Manually synchronize the 4-byte ISN between the CAS, EGS (gearbox), and DME (engine) modules.
- Edit Core Data: Full control to change VIN, ISN, Mileage (KM), Power Class, EGS Status, and key frequency.
- ELV OFF: Programmatically disable the Electronic Steering Lock (ELV).
- Full Key Management: View, save, and load data for all 10 key slots in the CAS module.
Hardware & System Information
Important: How to Identify Your CAS3 Version (CAS3 vs. CAS3+)Before using this tool, it's critical to understand which version of the CAS3 module you are working on.
- Check the Part Number on the Sticker (Easiest Method): Look at the label on the white plastic case of the CAS module. If the BMW part number (P/N) starts with a 9 (e.g., 61.35-9147227), it is CAS3+. If it starts with a 6 (e.g., 61.35-6943834), it is the older CAS3.
- Read the Processor (MCU) Mask (Most Accurate Method): This requires opening the module. CAS3 typically uses mask 0L01Y. CAS3+ uses the more secure masks 0L15Y or 0M23S, which this software is designed for.
- Operating System: This software was tested and confirmed to be working on Windows 10 Enterprise LTSC (2019). It is expected to be compatible with other versions of Windows 7, 8, and 10.
To read the required 4KB EEPROM dump from the CAS3+ module (MC9S12XDP512), you will need a reliable hardware programmer. Commonly used tools include:
- XPROG-M
- UPA-S (UPA-USB)
- Orange5
- VVDI Prog
- Rosfar
