Some users encountered Error N820 while attempting online programming for VW or Renault vehicles using the Launch X431 Pro5, and also failed to download the ECU refresh file. Error images are attached for reference.
Here is the solution:
1. Limited Online Programming Support:
The X431 Pro5 only supports built-in online programming for Benz and BMW.
It does not support online programming for VW, Renault, or similar brands.
2. Software Availability:
Online programming software cannot be purchased through the Launch Mall.
3. Recommended Tools for Full Online Programming:
To program modules for VW, Renault, Nissan, JLR, Porsche, Subaru, Hyundai, and other brands, you will need advanced diagnostic systems such as:
Launch X431 PAD IX
For comprehensive programming tasks, ensure you use the appropriate diagnostic system to avoid compatibility issues.
