Variable valve timing (VVT) in the Renault Megane optimizes engine performance by adjusting the timing of the opening and closing of the engine's intake and exhaust valves. This technology allows for improved efficiency, reduced emissions, and enhanced power delivery across different engine speeds and loads. By varying the valve timing, the Megane can adapt to driving conditions, providing a balance between performance and fuel economy. Renault's implementation of VVT contributes to its engines' responsiveness and overall driving experience.

You turn the valve cap anti-clockwise!
According to Wikipedia, a variable valve timing is a "process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions".
there isn't a drain plug, you will have to remove the bottom hose
For a Renault Megane 2.0 8-valve engine, the timing marks are typically located on the crankshaft pulley, camshaft, and sometimes an auxiliary belt cover. When aligning the timing marks, the crankshaft should be positioned at TDC (top dead center) for cylinder one, with the camshaft marks aligned accordingly. It’s crucial to ensure that the timing belt is installed correctly to maintain proper engine synchronization and avoid potential damage. Always refer to the specific service manual for your vehicle to verify the exact positioning and procedures.
Common problem have Solenoid replaced Usually the pressure regulator valve.

Variable timing valve train
Variable valve timing.
The idling speed is automatically sensed ....and set by the Air control valve
This component is electrically operated by the engine computer. It (on most vehicles) changes the oil pressure in the variable valve timing system to adjust the valve timing. It is very similar to the solenoids in use inside an automatic transmission.
