I'm John and I have a 2000 jetta. I am a mechanic and I found this website while I was seeking immobilizer info as mine activated when I changed the battery. I hope to find some useful information and maybe I can help some others as well.
If you're a mechanic definitely get vag com. It's an invaluable tool. Too bad it can't get the SKC number for you. If someone wants to steal something in the car they can just break the window. If they want to steal your car, they can just call a tow truck.
