Perhaps what I mean by needing a log in number, is that when I go to try and recode something the program asks me for the code for that control module. I don't get the key/car symbol when I turn it on. Even the dealerships don't know it, it get's downloaded electronically and input directly by the service tool. The login code is what you need, and it's a Fort Knox like secret kept by VW. As far as I know, only VW can service the newer immobilizers. If it is the immobilizer that's giving you difficulty, you will have to take it to the dealership to get resolved. If either are not paired to the cluster, engine start is prohibited (Actually, it runs for a couple of seconds than dies.)ĭo you get any lights on the instrument cluster (Namely a car outline with a key over part of it., or a message in the MFD?) VCDS- Windows Based VAG/VAS Emulator VCDS Version: 14. It reads the RFID of the key and the pairing of the ECU. The Immobilizer function resides in the instrument cluster. As far as I know, the only time an ECU needs re-mating is when there's some kind of immobilizer service being performed.
