In this video, you will see how to activate the cornering function of the fog lights on the Megane IV: you will use the DDT4ALL program and, of course, you will need an OBDII interface; the one recommended by our YouTuber can be found on Amazon with the code B074SD3VD5 at a price of £29.99, with free delivery.

Connect and search for your car model, go to the UPC-EMM control unit, then select the second USM-CMF1, and double-click on the lower cluster: the control unit takes a moment to load.

Look for the section related to lights, then select "lights" (it will prompt "configuration": confirm). A page will open, and you need to modify "cornering inhibition" to 1 (which is true in binary code); you need to set the inhibition to false, which means you should write 0 (false in binary code).

Press "send" and the modification is complete. For safety, turn off the car and leave it off for a few minutes.
