Hello everyone, I have a question regarding the high beam assistance systems of the Audi A4 B9 — more specifically, how to identify the different lighting features from the outside without turning on the ignition. Background: I am considering buying an Audi A4 g-tron. Unfortunately, many sellers do not really know which equipment their vehicle actually has. Therefore, I would like to be able to identify these features directly from the pictures on mobile.de listings. As far as I know, there are the following lighting assistance systems: a) Classic high beam assist This system has existed since the late 1990s. It simply switches the high beams fully on or off when detecting oncoming or preceding vehicles. b) Matrix LED / selective high beam assist With this system, individual sections of the high beam can be switched on or off separately, usually via Matrix LED headlights. This makes it possible, for example, to avoid dazzling a vehicle ahead while still illuminating the roadside areas to the left and right. c) Cornering light In this case, the headlights actively swivel into the corner when steering. I do not mean the common solution where only the left or right fog light turns on, but an actual swiveling low or high beam system. Now to my actual questions: a) How can I recognize from the outside whether the car has Matrix LED headlights / selective high beam assist installed? I assume there are visible differences in the headlights themselves. b) Are cornering lights and Matrix LED / selective high beam assist always combined? In other words: Can I assume that a car equipped with Matrix LED / selective high beam assist automatically also has cornering lights, or were these systems available independently from each other? Thanks in advance for your help!
