Mechatronic Solenoid Valves (MV), Pressure Regulator (EDS) (Without M54 Engine Up to 2004_03)

Mechatronic Solenoid Valves (MV), Pressure Regulator (EDS)

The Mechatronic (E-module and hydraulic selector unit) has 3 solenoid valves and 6 pressure actuators.

Each pressure actuator is individually geared to the Mechatronic and cannot be replaced.

Brief description of components (solenoid valves)
The solenoid valves are 3/2-way valves, i.e. valves with 3 connections and 2 switch positions.

They are activated by the E module. A solenoid valve can have the position OPEN or CLOSED.

Brief description of components (electronic pressure actuators)
The electronic pressure actuators convert electrical current into a proportional hydraulic pressure. This energizes the hydraulic valves in the switching unit that are part of the switching elements.

Two types of electronic pressure actuators are fitted:
- Electronic pressure actuators with rising characteristic curve.
Electronic pressure actuators 1, 3 and 6 can be recognized by their green caps.

Pressure range 0 to 4.6 bar
Operating voltage 12 V
Resistance at 20 degree C = 5 Ohms

- Electronic pressure actuators with falling characteristic curve
Electronic pressure actuators 2, 4 and 5 can be recognized by their black caps.

Pressure range 4.6 to 0 bar
Operating voltage 12 V
Resistance at 20 degree C = 5 Ohms
