I bought it to get PIN code to code additional keys and transponders for remote start on my D2 S8 and C5 A6 which I have done successfully and since I have PIN's now I have no more use for it now. It does offer pretty much all of the diagnostics that VCDS would and also single function key coding but for me if I just did key coding straight from it engine would work with the key but immo lkght were flashing and it was showing error code 'key incorrectly coded' so I just used code I got from it with VCDS and it worked just fine. I bought it as it was a cheapest way to code key on my S8, there are cheaper tools that will do D2 1994 -1996 with white immo box but very few for black immo box 1997-1998. It will not work on petrol FL D2's but should work on early D3's from what I understand but never tried myself.
Here is an example with details;

I paid £80 couple of years ago, the price has gone down since and I will be happy with £40 +postage costs
