Turbocharging; Pressure Regulating Valve - Renault 2000 Megane Technical Note

The LDA (A) of the pressure regulation valve is controlled by a solenoid valve (B) which is controlled by the injection
computer. This solenoid valve varies the underpressure as a function of the engine operating ranges, which allows
the turbocharging pressure to be regulated.
The pressure regulation valve is open in rest position. The engine operates as normally aspirated.
The solenoid valve, closed in rest position, is supplied after starting the engine, after a delay dependent on the coolant
temperature.
