Well, there are two options: 1) You do it the safe way. Have it installed at the dealership, submit an inquiry, wait, hope for approval, learn how to do it, remove it, and adjust the mileage. 2) You learn as a child never to listen to your parents or anyone else, so you do it yourself and stubbornly insist on your own way, which usually ends badly. (Applying the Seat dump to Skoda is a bad idea.) I opted for the second option and made things complicated for myself. Long story short, I ran into a TPI situation, meaning the control unit is fully diagnostic-capable, but the display remains dark. This often affects 2019 model years, specifically the first generation XXX920790 without an index or with index A Virtual Cockpit Generation. So, Immobilizer Generation 5A. If the software glitched, it can be fixed by flashing the complete firmware. If the software has glitched, it can be fixed by flashing the entire firmware. Long story short, I ran into a TPI issue. Then I remembered I bought a defective Kodiaq Virtual Cockpit last year with the same problem... Okay, Virtual Cockpit can only be flashed with an unlocked immobilizer... Great, I have two Virtual Cockpits, both with different VINs, of course, and I need an unlocked immobilizer... What do you do? Right, screw it, get down in the car, remove my own Virtual Cockpit, make a data dump (praying the rosary that the thing stays intact), and flash the dump to both Skoda Virtual Cockpits... What can I say, it worked perfectly. The immobilizer, CP, key, etc., were all transferred correctly. Back in the car, connected the defective "Virtual Cockpits," didn't give a damn, turned on the ignition, and started it (note: if a different VIN is detected, the ABS coding is automatically set to 0, and all basic settings of the ABS block are lost). The car started right up, the coolant temperature and fuel gauges worked immediately, the turn signals worked, etc. That means the immobilizer was completely transferred. What can I say? It worked perfectly. That means expecting a long flash this weekend.
