Set Clutch Parts 6-speed SMG (2.5)

The selection solenoid valve (marked with “OOV”) is responsible to move the gear selector sideways to select the gear pairs. In the case of failure of this valve, the car will refuse to go into one or more gears.

This is an original and new Magneti Marelli spare part.

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.

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 shift solenoid valves (marked with “PPV”) are responsible for changing the gears of the SMG system. There are two of these valves on the hydraulic unit. Together with the selection valve, they operate the shift actuator. If one of the valves is faulty, the car will refuse to go into one or more gears.
