WFS Code: Definition and Examples

Hi, I received the four-digit WFS code today.
I'd like to try it out now to see if it works with VAG vehicles.
Where do I need to enter something to see if it works?
I entered it under "immobilizer (25)" in the login section, and then it reported an incorrect code and instructed me to turn off the ignition.
And then again, when I tried accessing the "Kombiinstrument" (17) under "Login," it didn't work, and it just went back.
Okay, so now I'm in a fix. The immobilizer warning light is constantly illuminated on the dashboard, but the car still starts. However, there are no error codes stored in the system.

Does anyone have any advice?

Best regards, Dominik.

What car are we talking about? What code did you enter, and for what purpose? Are you trying to play a game, or are you trying to pair a key?

I have a Seat Leon, model year 2001.
"Please provide the exact code for key programming and speedometer calibration."
I just wanted to see if the code works.

Best regards, Dominik.

I don't want to start picking everything out of you. I would like to ask for more information. That means the process, which code, where it comes from, how exactly it is entered, lock-out times, etc. Otherwise, just go to a Seat dealer, they can do it.
