Early production NAR Cabrios with 25- Immobilizer part numbers beginning with 6H0 are Immo 2/Gen 2. The North American Region (NAR) market VW Cabrio used two different generations of Immo 2, depending on whether the vehicle was built before or after 05/1999.

If in doubt, check the Factory Repair Manual for your specific vehicle. There should NOT be a 17 digit VIN Number in the Extra Fields. You should see a 14 digit Immobilizer ID Number such as Immo-ID VWZ7Z0W0648696. To identify an Immobilizer 2 Vehicle, use VCDS to Select the Instrument Cluster (or Address 25 - Immobilizer in Vehicles with a separate Immobilizer Control Module) and look in the Extra Field. Many 2000-2001 Model Year Vehicles sold in the North American Region (NAR) have Immobilizer 2 and there are other Rest of World (RoW) Vehicles with Immobilizer 2 which started earlier than that around Model Year 1998.

#What is vcds 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). 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.
