the mileage isnt as important as the time and speed the drive cycle does. it sets the parameters for the testing station to read. it has to be done in the specific pattern the link says to.
i dont know of a shop close to you i can recommend but buckhead imports in atl can read any issues with star das software. if you post the vin im sure the database here can tell you if its a forum car and any mods it may have
sorry i couldnt be more help
