How to Clone Ford Focus MK2 Cluster with Xhorse VVDI Prog

In this tutorial, we’ll walk through the process of cloning a Ford Focus MK2 instrument cluster (Part No.: 8V4T-10849-HH) by reading and writing its EEPROM and Flash data using the Xhorse VVDI Prog tool. This procedure is useful for replacing a faulty cluster or performing repairs while retaining the original vehicle data.

Tools Required

1. Xhorse VVDI Prog

2. MC9S12 Cable

3. Screwdriver/Pry Tool (to open the cluster housing)

4. Replacement Cluster (same part number as the original)

Step-by-Step Procedure

1. Accessing the Instrument Cluster

• Remove the instrument cluster from the dashboard by gently prying it out. Releasing the clips on both sides allows the cluster to slide out easily.

• Once removed, locate the EEPROM and Flash memory chips on the circuit board.

2. Connecting VVDI Prog

• Use the MC9S12 cable to connect the cluster to the VVDI Prog tool.

• Follow the pinout diagram in the software to ensure correct wiring:

  • Power (VCC)

  • Ground (GND)

  • Reset (RST)

  • Communication lines (PCC, etc.)

3. Reading EEPROM & Flash Data

• Open VVDI Prog software and select the Ford Focus 09-10 dashboard option.

• Click “Read” to extract:

  • EEPROM data and save.

  • Flash data (saved separately)

• Verify that the readings are successful before proceeding.

4. Writing Data to the New Cluster

• Once the replacement cluster arrives, connect it to VVDI Prog.

• Load the previously saved EEPROM and Flash files and click “Write” to transfer the data.

• Ensure all mileage, immobilizer, and settings match the original cluster.

5. Reinstalling the Cluster

• Carefully reinstall the cloned cluster into the dashboard, securing all clips.

• Test the cluster by turning on the ignition to confirm functionality.

Important Notes

• Compatibility is critical—the replacement cluster must have the exact same part number.

• Improper wiring or data transfer may corrupt the cluster, so double-check connections.

• This process may require additional coding for full vehicle integration (e.g., immobilizer sync).
