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.
