Keydiy KD-MP MQB48 Stuck on Self-Checking Page Solution

Problem:

Tried to read an original Audi A3 2018 MQB48 key data with Keydiy KD-MP tool and KD’s MQB48 clip adapter.
Kd Mp keeps failing. Tried replacing the key in different positions.
Tried putting pcb flat, etc
How to fix it?

Possible reasons and solutions:

1. The GND connection is wrong. Put the clip in the battery + place.
(Top side of cr2032 +, bottom part -).

2. Try put the spunge in and power the device.
