Hello everyone, question about immobilizer audi a4 b5 1.9tdi 2000 immo2 or immo3

Hello, I'm a new user, I write from Italy. I want to change tacho to my a4 b5, I have the pin of the new tacho, but I do not have the old one! I can not tell if my car is immo 2 (so I do not need of the old pins) or immo 3 (so I need an old pin)! in channel 17 vcds in the extra field I have "xxxxxxxxxxxxxxxxx auz5z0s4057019"!
I know that immo 2 does not know the vin auto, but it should be different from the "x", so I do not understand.thanks

Please post an Auo-Scan for context.

I think these cars had Immo-2, but the cluster was "Immo-3 ready".
