Climatics

Hello, everybody.

I have a brief question about the climate control part. I've already looked in the search, but I haven't found a definite answer. What part number does the control panel have in the V8 year 93, i.e. the "large" display?
Do devices fit with other end letters?

Then I read something that the part had to be "re-learned" after the replacement...What's the matter with it?

Thank you!

Greetings Luke
