So to make that clearer.

In Step 2 don’t select Smart Vin or Imput it by typing in the VIN.

Manually input YOUR cars data..... so BMW....X5(e53)......2005.....Diesel/Petrol.....so on and so on.

That should work then, if not.... if you car is within a year of the LCI model you can select a differnt year so for example my car is a 2005 and the LCI was 2004. I would select 2004 and then see if I could connect to the module.
