Clutch Solenoid Valve 6-speed SMG
The clutch solenoid valve (marked with ‘QPV’) is responsible for actuating the clutch in the SMG 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.

Pump Relay 6-speed SMG E46
The pump relay is responsible to turn on / off the hydraulic pump of the SMG system. A broken relay causes the pump to fail priming. Without hydraulic pressure, the system cannot engage the clutch or change gears.
Pictures shown are for illustration purpose only. Fits only E46 models.

Shift Solenoid Valve 6-speed SMG
The shift solenoid valves (marked ‘PPV’) are responsible for engaging the gears in the SMG 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.

Selection Solenoid Valve 6-speed SMG
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.

Pump Relay 6-speed SMG E60 E63 Z4 E85
The pump relay is responsible to turn on / off the hydraulic pump of the SMG system. A broken relay causes the pump to fail priming. Without hydraulic pressure, the system cannot engage the clutch or change gears.
Pictures shown are for illustration purpose only. Not for E46 models.

Selection Sensor 6-speed SMG
This sensor is located on top of the gearbox and responsible to monitor the shift process. Our sensors are brand-new OE aftermarket replacement parts.

Transmission Speed Sensor 5- / 6-speed SMG
This sensor provides the speed signal of the transmission input shaft. The speed signal is required by the SMG control unit to control the transmission system, adjusting properly the shaft speeds before engaging and disengaging the different gears.
