Keydiy KD-MP MQB48 Server Self-Check Failed Error

Problem:

Keydiy KD-MP tool reads original MLB keys without problem. It’s not a network issue.

But it does not work with MQB48.

It reads key ID, load it up to the server then comes back with this error: Server self-check failed.

Where is the issue with it?

 

Solution:

Keydiy released new software version for KD-MP MQB48/MLB data collection.
Current version: V1.8.7 (Feb. 2026).
New software version fix key reading bugs.

If the problem exists when the software is up-to-date, change key position and try again.
If all failed, contact Keyidy customer service.
