Control Unit 5-speed SMG
The transmission control unit (ECU / TCU) is the main computer responsible for the control of the 5-speed SMG.
Please mind: The product photo is for illustrative purposes only. Please ask us which specific part number we have in stock before purchase. There are various part numbers of this ECU, some of which are compatible with each other. Some ECUs need to be coded or flashed after installation. Checking the compatibility is your responsibility, a return is not possible.
Pressure Accumulator 5-speed SMG
The pressure accumulator is responsible to store the pressure of the hydraulic system for later access by the actuators. This piston type accumulator has two cells: one cell storing the hydraulic fluid and one cell containing a Nitrogen gas filling which creates the counterpressure. Both cells are separated by a moving piston. Typical symptoms of a faulty pressure accumulator are frequent and short pump cycles. If there is no more preload pressure left in the accumulator, the pump runs every few seconds, which ultimately leads to a consequential damage of the pump motor. Along with the pump motor, a faulty pressure accumulator is one of the most common causes of pressure build-up issues and is one of the few wear parts in the system that should be regularly checked and replaced if necessary.
We offer a brand-new replacement accumulator.
Selection Solenoid Valve 5-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 Motor 5-speed SMG
The pump motor drives the gear pump, which generates the pressure for the SMG transmission. Both parts together form the hydraulic pump. Without hydraulic pressure, the transmission cannot perform any action – neither change gears, nor operate the clutch. Therefore, the hydraulic pump is the most important component in the system.
In most cases, it is sufficient to replace only the electric motor, as this is a wearing part. The gear pump fails only very rarely. Another advantage is that when only the pump motor is changed, the hydraulic system does not need to be bled afterwards, unless it has been opened.
We sell an original, brand new Magneti Marelli spare part – the same part you would get from BMW.
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.
Shift Sensor 5-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.
Shift Solenoid Valve 5-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.
Pressure Sensor 5-speed SMG
The pressure sensor measures the hydraulic pressure in the accumulator. Based on this value, the SMG enables and disables the hydraulic pump to fill up pressure. This is a brand-new original part.
