You connect to the meter, i.e. choose the address meter 17.
Later, when it connects, it will show you the meter number 8P0920xxx, VIN number of the car and below on the right you can choose something like coding (address 07). You choose coding and change what I wrote earlier there, before changing what you write there.
Below is an example, but in English, the addresses are identical, Coding [07] and the current coding can be seen on the top left, Soft Coding, VAG Number is the driver number with which you connected and there you should see No. 8P0 920 XXX and in these empty windows below you will see VIN of the car.
