Control Unit 6-speed SMG
The transmission control unit (ECU / TCU) is the main computer responsible for the control of the 6-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.

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 Motor 6-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.

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.
