I bought an audi tt but found out that my car doesn't have headlight warning buzzer, also upon exiting the car I don't get any kind of reminder to turn off headlights when I take the key out and open the door. once it was missing radiator fluids and it heated up it dint buzz. I forgot my lights on a few times would like to get my buzzer working, Anything need's to be replaced, or any fuse checks? and yes when i open the door the window drop and the dash light up when door opened.

thanks for any help.
