Go to to store this EEPROM binary file ( .bin or .eep ) as a backup on your local drive. Risks and Safety Best Practices
The limitation stems from its reliance on the K-Line for communication. Newer vehicles use more advanced, encrypted CAN-Bus (Controller Area Network) systems that this older tool cannot access.
The tool is designed to interact directly with a car's (Electrically Erasable Programmable Read-Only Memory), which stores critical configuration data that remains even when the power is cut. Key tasks often performed with V1.20 include:
: Adjust the digital odometer display if you replace a broken instrument cluster.
The is a Windows-based software suite designed to read, modify, and write this data. It communicates with the vehicle’s modules via a specific hardware interface, most commonly a VAG KKL cable (a 409.1 OBD2 cable) or a dedicated EEPROM reader like the UPA-USB or Carprog .

The software is designed for Windows-based PCs and supports the following operating systems:
Common on Motometer/Bosch clusters. If this occurs, look for the "Testing code" in the progress window, record it, and use the function to manually resume the process. Resetting the Cluster: After writing a new dump, it is best practice to click to power-cycle the instrument cluster and apply changes.
One rain-soft afternoon a local mechanic named Marta pushed open Luca’s garage door with a problem: a 2006 VW Golf that stalled intermittently. The car’s owner had been told the issue might be a faulty EEPROM—corrupted data inside the vehicle’s electronic brain. Marta had tried standard diagnostics but needed a low-level programmer to read and write the module’s memory. She’d heard Luca could coax secrets from stubborn chips.
Modify the required data and click "Write" to upload the new configuration. Supported Vehicles (Approximate) Go to to store this EEPROM binary file (
: The user connects the vehicle's OBD port to the computer, usually via a compatible cable or interface.
Connect a battery maintainer or charger to the vehicle during read/write sequences. A sudden drop in voltage will corrupt the chip data mid-transfer.
Select your cluster type (e.g., RB4), enter the new value, and click Write New Mileage Clear Airbag Data SRS Airbag from the dropdown and click Clear SRS Airbag Errors 4. Troubleshooting Common Errors "No ECU Found":
The software interfaces with the vehicle via a standard OBD-II port using an inexpensive , typically powered by the FTDI FT232RL chip. Unlike modern diagnostic suites that only read fault codes, this tool interacts directly with the non-volatile memory chips (such as the 24C02, 24C04, or 95040) inside the vehicle's modules. Key Capabilities and Functions The tool is designed to interact directly with
Flashes a modified memory file back to the cluster.
Navigate to the Mileage tab. Enter the desired value in the Mileage field. Click Write . The cluster will accept the new value and display it upon restart.
The tool provides deep access to older vehicles built between . Popular supported models include the Golf Mk4, Passat B5, Audi A4, and Skoda Octavia A4.
Plug your KKL cable into the laptop and the car’s OBD port.
