I will post the scan here my brand new friends. I'm really happy by eventually found a fora which actually gives me a good feeling about my questions really are making progress allready. Thank you very much...... Back to the car..... Ok it had a quite har hit but for some reason non of the airbags deployed. And no ecues have ever been replaced. I have another used ecu which somone delivered to me but still not replaced it. Correct me if I think wrong... But I have an idea abt, if my diagnose equipment are able to communicate whit the ecues in a high speed and no sign of faults, which I can do all the programming or read all live data en so on, I belive the ecu is just fine. But what that causes this ecu to sudden lost the authorization as a member of the security circle I really can not understand. And when that ecu are not athorized I belive that to also be the reason why the message about the immo system are active in the dash also. I have a few thoughts about it, but I really need to get it started ASAP since no car, no work and nothing to have food on the table. I have an obd 2 immo deactivation that works at least on 2000 Audi s8 but I don't dare try it on my t6 since it's about 4 generations between them. But at the other side I have my autel Pro that they guarantee should do about whatever I want but I have really not been able to redraw the immo security code whit it either
