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.
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.
Clutch valve 6-speed SMG
The clutch solenoid valve (marked with “QPV”) is responsible for the clutch actuation of the SMG system. A faulty valve can cause problems while engaging the clutch (for example shuttering) and in consequence the car refuses to change gears.
This is an original and new Magneti Marelli spare part.
Pressure accumulator 6-speed SMG
Our refurbished pressure accumulators are equipped with a filling valve and freshly filled with new nitrogen gas.
The accumulator is responsible to store the pressure of the SMG system for later access by the actuators. The piston type accumulator has two cells: one cell storing the hydraulic fluid and one cell containing a gas to create counterpressure. Both cells are separated by a moving piston. A broken accumulator causes the pump to prime permanently.
