Haha sorry for the abbreviation Lee, it's the Driver Information System. I think on mine if you press the Car button the External Lights option is displayed. If you scroll down the it, the DRL's can be turned on/off and also the sensitivity to the ambient light for the headlights to come on when set to the Auto position. If you are still having issues getting the DRL's to work it may be worth calling in the services of a local VCDS specialist to sort it for you.
