How to Add 2020 Seat Leon MQB Key with VVDI Prog and VVDI2

We’ll walk through the process of reading EEPROM and immobilizer (immo) data from a 2020 Seat Leon MQB dashboard cluster and add a spare key using Xhorse VVDI Prog and VVDI2 key programmer.

 

Tools Required

 

Step 1: Disassembling the Dashboard Cluster

  1. Remove all screws securing the instrument cluster.
  2. Open the dashboard carefully to access the processor (MCU).
  3. Identify the processor type to determine which MQB adapter is needed.
  • The adapter must sit perfectly on the board. If misaligned, the tool may fail to read data (showing errors or incomplete extraction).

Step 2: Reading the EEPROM Data with VVDI Prog

  1. Connect the Xhorse MQB adapter to the processor.
  2. Start the reading process—the tool will extract the EEPROM data.
  3. Once complete (100% progress), save the file

Step 3: Extracting Immobilizer Data

  1. Open VVDI2 software and select:
    • Seat > Leon > MQB > BCM (Body Control Module)
  2. Load the saved EEPROM file.
  3. The software will calculate and generate an immo data file

The tool connects to a server to generate immo data, so a stable internet connection is necessary.

Step 4: Programming the New Key

  1. If inside the car:
    • Connect the vvdi2, load the immo file, and follow the prompts.
    • For adding a key, use the existing key for authentication.
    • For all-key-lost cases, sync data is required.
  2. Insert the new key when prompted, and the system will sync it.
