Pressure accumulator BMW E60 M5 E63 M6 SMG III
Our refurbished pressure accumulators are equipped with a filling valve and freshly filled with 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.

New SMG III pump motor for BMW M5 and M6
- Equipped with original plug
- Perfect for sporty driving style & frequent shifts

The pump supplies the hydraulic pressure for the different consumers (actuators) of the SMG and stores it in the pressure accumulator. The pump consists of a small gear pump and an electric motor. If the pump motor fails, pressure is lacking in the system and the SMG cannot perform any clutch operations or gear changes.
Pump relay BMW E60 M5 E63 M6 SMG III
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. The relay in your car may have a different color.
Transmission speed sensor BMW E60 M5 E63 M6 SMG III
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.
