Went to view an A4 B8 at the weekend and the LED DRLs only came on when you turned the switch to sidelights. This also put on the rear tail lights. The 'Auto' setting didn't have them on when stationary. Is this right on the A4?? I thought there would be a DRL setting. My A3 has DRL for the first turn of the switch and just puts the front DRLs on.
