Guys, I have got myself a scanner 1.4/PASoft and am aware of a couple of issues with the car, but also aware that the scanner may report historical data, therefore whats the best approach when using the scanner. Is it best to clear all the error codes, drive around for a while and then run a error scan? Does the "Clear DTC" clear all errors?

Also, within PASoft, why are they 2 error columns? and you also have "faults currently present" and "faults not currently present" are the "not currently present" historical faults? and if so, how do you clear them to get a level playing field?
