z4 2.2i central locking confirmation

Hello together, I have a question: After the conclusion by FFB my old 320td had always “linked” me. So I wanted to have the z4 again. Unfortunately it did not at the pickup!! The statement of the master was: “That’s not possible with the model” My salesman could only wonder about this statement and the master was not there anymore. Now the question: Can he do that or nciht?? Who of you also has a 2.2i and can tell me what is going on and what is not. Point: I accept this light on the mirror, for the alarm system. ABer I now have one or not??? Is not on the invoice as a special equipment/series equipment. The vehicle is probably from end 2003/ beginning 2004 (how can I find out?) Thank you already for your help. PS: With my 320td compact the master also said it wouldn’t work (hahaha, gone) Greetings from Düsseldorf Swen
