Polo daytime running lights

Was asked to look at a VW Polo with drls and asked to turn them off! Found this info but decided not to try it as they are on for a reason. To turn them off, switch them off as follows on a Polo. Insert key in ignition, but don't turn it. Turn the headlight switch to the "0" position. Move the indicator stalk to the left position and pull towards you, as though you were flashing a warning at another car. Turn the ignition on, but not the engine. Wait at least four seconds and you should hear three bleeps to indicate that the DRLs have been deactivated."
