Im looking to upgrade my 2002 S3 to an A5 Sportback. I went to look at one yesterday (2010 S-Line 2.0TDi) but i'm confused about the DRL's. I always thought that when the keyfob is pressed to open the car, the front LED's illuminate, however this didnt happen on this particular car. Also, ive noticed some cars have "Auto" on the light switch, the car I looked had didnt have this. What is the purpose of the Auto function.
I turned the switch to the side-lights to have a look at the DRL's, but when I looked at the LED's they didnt seem very bright, just like a dim LED backlight. Im now confused, any explanation would be handy please.
