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.
Important: You will need to pay a core charge (deposit) of 300,00€ which will be refunded when you return your used part. You can learn more here. This is a repair service (no purchase of a product). Our terms and conditions and the right of withdrawal for the order of services apply.

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.
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.
Pressure sensor BMW E60 M5 E63 M6 SMG III
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.
