: Can read, write, and modify immobilizer data to help swap ECUs or instrument clusters.
The only compatible interface is a with a USB connector, often based on the VAG-COM 409.1 standard. These are widely available as inexpensive "blue cables" and are sometimes branded as "Vag K+Can Commander 1.4".

Correcting mileage after replacing an instrument cluster with a used unit. 4. Immobilizer On/Off (IMM OFF)
Download the VAG EEPROM Programmer 1.19g. The "G" suffix is important, as this version introduced the necessary optimizations for Virtual COM Port (VCP) USB-to-Serial communication.
: Downloads complete .bin memory maps, allowing users to toggle between encrypted and decrypted views to find configuration bytes. : Can read, write, and modify immobilizer data
: To program new keys or swap an instrument cluster, you need the vehicle’s 4-digit or 5-digit SKC (also known as the PIN). The software reads the encrypted cluster data and decrypts it to display this code directly.
Retrieves the 4-digit or 5-digit Secret Key Code (SKC) needed to adapt new keys or match replacement clusters using platforms like VCDS.
such as the Golf Mk5, Passat B6, Audi A4 B8, or any vehicle that primarily uses the CAN-Bus protocol for diagnostics. Attempting to use it on these cars will likely result in a "No ECU Found" error. Drop the down from the default 16ms to 1ms
The software reads and writes to the Electrically Erasable Programmable Read-Only Memory (EEPROM) embedded within vehicle Electronic Control Units (ECUs) and instrument clusters. Unlike generic diagnostic scanners that only clear fault codes, this tool targets the raw hexadecimal data where the vehicle’s identity and security profiles live. Key Functions
Choose the appropriate option (e.g., "Bosch," "VDO," or "Magneti Marelli") based on the vehicle manufacturer.
Expand and open the properties of your USB Serial Port. Navigate to Port Settings > Advanced .
For VAG vehicles with early immobilizers (Immo 1, Immo 2, and early Immo 3), the 119g can read the EEPROM from the instrument cluster or ECU to extract the SKC (Secret Key Code) or apply "Immo Off" patches.
The most common use case. VAG vehicles store mileage in EEPROM chips (usually 93C66, 93C86, or 24C64) on the cluster PCB.
