Clutch Solenoid Valve – Mercedes Benz Sprintshift / Sequentronic
The clutch solenoid valve (marked with ‘QPV’) is responsible for actuating the clutch in the Sprintshift / Sequentronic system. A faulty valve can cause problems with clutch engagement, such as shuddering, delayed and harsh engagement, or even a complete failure of clutch actuation.
Selection Solenoid Valve – Mercedes Benz Sprintshift / Sequentronic
The selection solenoid valve (marked ‘OOV’) is responsible for moving the gear selector sideways to select gear pairs. If this two-way on/off valve fails, the car may be unable to engage one or more gears. Note: the product photo is for illustrative purposes only, the valve is supplied without the Magneti Marelli sticker.
Shift Solenoid Valve – Mercedes Benz Sprintshift / Sequentronic
The shift solenoid valves (marked ‘PPV’) are responsible for engaging the gears in the Sprintshift / Sequentronic gearbox. There are two of these pressure-proportional valves mounted on the hydraulic unit. Working in conjunction with the selection valve, they operate the shift actuator. If either valve is faulty, the car may be unable to engage one or more gears.
