Light warning buzzer no longer works after renovation KI

Hello!
I exchanged my old KI (MFA with pixel errors) for a new one last week.
My old (Passat, year 2000) had CAN-Bus and WFS II, the new (Passat, year 2003) of course also has CAN-Bus but with WFS III.
But everything still worked perfectly with the login and key encoding, and everything is also working.
The only exception: the light alarm buzzer no longer works!
Initially, I didn't mind, but now that I've forgotten to turn the light on several times, I'm realizing how useful this function is.
During the contact point diagnosis, the buzzer functions correctly.
Does anyone know how I can reactivate the summer?
Thank you in advance!
