Audi models as well as the early VW Passat (3B) may show different Serial Numbers, so this does NOT apply to these models.
#VCDS VS VAGCOM SERIAL NUMBERS#
All VW, Seat and Skoda Immobilizer 1 Serial Numbers contain 3Z (for Example VWZ 3Z0S1101234), if you see something else there it is unlikely you have this Generation at hand. Immobilizer 1 can also be identified via the Immobilizer Identification/Serial Number.

If in doubt, check the Factory Repair Manual for your specific Vehicle. Immobilizer 1 Vehicles were sold in the Rest of World (RoW) Market only, not in the North American Region (NAR). Keys for vehicles with Immobilizer 1 usually have a small F on the key blade, which stands for Festcode (Fixed Code).
If in doubt, check the Factory Repair Manual for your specific vehicle. The key may also have a W with a strikethrough to indicate that Immobilizer isn't present. None: Cars without Immobilizer will not have a symbol in the instrument cluster showing a key inside a car and will start and run as long as you cut a new key that is able to turn the ignition.
In some cases other Modules or Parts may be Immobilizer related as well, for example newer Audi Models also have the Transmission as Part of the Immobilizer. The components of the Immobilizer system that require special procedures for replacement include the keys, Engine controller (ECU), and the Instrument Cluster (or the separate Immobilizer modules in vehicles so equipped). Several different Immobilizer schemes have been used for different years and different models of vehicles with different procedures that apply to them. The Immobilizer prevents the car from running unless an authorized key is present and has been properly matched to various components in the vehicle.
