Note: it should appear each time when you diagnose that your VCI is old and blablabla, just click continue and it connects to the car

Note2:  it might not be 100% compatible with all cars as it is the old interface and does not do the multiplexing like the newer one. I tested on a few cars from 2000 to 2015 and for 300euro it is worth adding to collection!
