Audi A4 1.8t B5

Hello everyone !!, I am new in this forum although I have been in MDM's blogs for more than a year, I am not very good to present myself but, I am a dragon40.Intetodo congratulations on the forum. As some of you I am fond of mechanics and I have made my steps in this mechanics , but I would not want to be rude or make any mistake.
I tell you my little problem, I have an Audi A4 1.8t B5 and I am failing in the immobile, I have checked the clauses, starting and drum connector and it seems that everything is ok, I have the vag 311.2n but I can not erase the failures because I have not activated it, I have looked for the Keygen but I do not get it anywhere.
It would be very helpful for someone to pass it to me.
Thank you so much.
