How to Activate the Cornering Function of the Fog Lights on the Renault Megane IV

Model: Renault Megane Megane 4, Megane IV - Years 2015-2023
Part: Fog lights

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.

How to Bleed the Clutch on a Renault Clio?

To bleed the clutch on a Renault Clio, open the bonnet to access the components located in the engine bay: here, you will need to undo the screws that secure the battery in its housing, the intake manifold, and the coolant reservoir. This will allow you to locate the pipe through which the brake fluid flows: by inserting the other end of the pipe into a container, you can press the clutch pedal to expel all the fluid until it fills the container.
