Hello everyone, I'm just coming from a disaster, and I'm about to go crazy if you don't help me. Apparently, this thing doesn't want to

.
I followed the instructions exactly, but this thing has a completely bizarre behavior. But let me explain in more detail.
One thing to mention upfront: The battery voltage was sufficient.
Zuerst RECODE ans M-STG durchgeführt, das WFS-Symbol blinkt die ganze Zeit. Dabei ist mir gleich was komisches aufgefallen, nämlich das das 'Soft.coding' gleich wie das vom alten KI ist

Gut, habe mir nichts gedacht und 'Do It' gedrückt. Dann Adaption-10 Channel 00 und Read. Links oben steht was von Satus:Save. Dann Done, Go Back. Close Controller, Go back und Zündung auf aus. Symbol hat vor Zündung=Aus immer geblinkt, auch jetzt nach Zündung=Ein um die Schlüssel anzulernen natürlich immer noch. Dann Login-11, den 4-stelligen code eingetippt (mit 0 vorne dran) und 'Do It'. Hat er brav geschluckt, denn ich komme danach super in Adaption-10 rein. Dann Channel 21 und Read. Er spuckt mir den Wert 2 aus. Den Value setzte ich mal auf 0 und mache Save, denn TEST ist immer deaktiviert! Dann auf 1 und mache Save (1 deshalb, weil ich schon verzweifelt war und 1 Schlüssel mal aktivieren wollte, bevor ich mich an den 2. wage). WFS-Symbol geht zum ersten mal aus! Juhu! Dann Done, Go back, Close Controller, Go back-06. Zündung auf aus und eigentlich wars das ja. If you want to program another key, you should insert the second key and wait until the symbol disappears after approximately 2 seconds.
So far, everything has worked. When I turn the ignition back on, everything is okay; I can start the car, and it runs. However, if I turn it off and then on again, the WFS (likely referring to a warning light system) starts blinking again. And now here's the thing: even though it's blinking, the car still starts and runs! Yes, it runs even with the blinking light! If I now use the other key, which I haven't programmed, the WFS continues to blink, and the car also starts with this second key. This works a few times, but then it won't start anymore. There are errors in the M-control unit and the instrument cluster. Here are some other funny things:
a) Even though the WFS (warning/fault system) light is flashing, it sometimes starts up, and then when I clear the error codes from the memory, it suddenly stops starting altogether!
b) Old AI will be immediately replaced with a mechanical system after the conversion.
c) The old key had a sticker with a code that needed to be scratched off. By chance, this is the 4-digit PIN that is also on the second key!
'Can anyone help me? I'm stuck and don't know what to do. Please help! I can answer any question, no matter how detailed, because I've been playing with this for over 2 hours! Could it be that it's not possible to adjust a Skoda instrument cluster using VAG-COM? I have a feeling that the RECODING didn't work correctly because the soft coding was identical to the old instrument cluster. But why does it work the first time, and then the WFS (warning flash symbol) starts blinking after the second start? It's possible that it still starts, and that works fine for a few starts. But it could also turn off after the second start. That's rare, though, usually happening after the 5th or 10th start. And why does the second key work (briefly), even though I didn't register it? Either I'm doing something wrong, and it's always the same thing, or the new/used instrument cluster has a problem with the WFS, and the seller misled me.'
Thank you for your help!
