An Electronic-Hydraulic Actuator (EHA) in a Mercedes is a component that controls the fuel pressure in the fuel injection system. It sits on top of the fuel distributor and contains a solenoid valve that regulates the pressure. The EHA uses an electric signal from the car's computer to open or close the valve, which changes the pressure and adjusts the amount of fuel being delivered to the engine. The EHA helps to ensure efficient fuel delivery and optimal performance of the engine.

The EHA is an important component in the Mercedes fuel injection system and can often be the cause of engine performance issues if it fails. Signs of a faulty EHA can include rough idling, poor acceleration, and decreased fuel efficiency. It is essential to have a functioning EHA in order to maintain the overall health and performance of your Mercedes engine. Regular maintenance and inspection can help to prevent issues with the EHA and ensure that your engine is running at its best.
