When I got the code read out, I didn't have the 'new' key with me so I note down the code thinking I will use a VAGCOM interface in order to have the key matched some days after. So it's a 5 digit one instead of 4 digit one having the first digit '5'. The software told me that my LOGIN code is 5****. I didn't find a Tacho but I did find a Commander and after a few tries regarding my cluster ( or ECU - not sure ) type I managed to log into my ECU using the Bosch Something setting so I figured that's the one I have. I don't have any 4/7 digit SKC code that came with the car so since the dealers no longer give these away since 2005, my only hope was to get the login code read out from the ECU via a Vag-Techo or Vag-Commander interface. Got the key blade cut, it works fine - it opens the door mechanically and gets the car to the START position, of course it doesn't start the car as the chip is not programmed to the car so I needed to do that.
I bought a used key off e-bay with a blank blade + a virgin transponder chip ( id48 ) and the remote of course matches the code/frequency of my single key that I have. So, I need to make myself another key for my 2002 Audi A4B6 ( 1.9TDI ).
