Question:
2005 Audi A8 Siemens kessy has lost all keys. Read 93c86 with VVDI prog and clip adapter. Not sure what to do next. It’s also a smart key and keyed ignition. Don’t know where to go next? Some insight would be great.
Solution:
Get pin. Program virgin key with login pin with vcds or vvdi2.
With Xhorse Vvdi2 go under VW immo4 you will see A8 last option load the file you will get the CS and the pin make a dealer remote and connect the Vvdi2 to the car and learn the key (only if your chip is ID46)
If it’s ID48 you can write it straight to the Eeprom with vvdi2.
If you try to open to get cs says unknown version. You should desolder and read again. Always de solder it just because the crystal.
We have a customer who did 2006 A8 today so it’s the same.
