Not a pressing issue, I'm just curious why some cars have one and some cars have the other...
My 2008 GTI has the AC button, whereas I've noticed on some pics that instead of saying 'AC' it says 'ECON' - my assumption is that this button has the opposite effect of the AC button on my car, i.e. when it is illuminated, the aircon is switched off.
Was it the earlier versions that had the ECON button?
