Clutch Solenoid Valve – Volkswagen Crafter Shiftmatic
The clutch solenoid valve (marked with “QPV”) is responsible for the clutch actuation of the Shiftmatic system. A faulty valve can cause problems when operating the clutch (for example shuttering) and in consequence the vehicle may refuse to change gears.
We are selling a brand new spare part.
Pressure Accumulator – Volkswagen Crafter Shiftmatic
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 hydraulic 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 more often.
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.
Pressure Sensor – Volkswagen Shiftmatic
The pressure sensor is responsible to detect the hydraulic pressure in the accumulator of the Shiftmatic system. This is an original and brandnew spare part.
Pump Motor – Volkswagen Shiftmatic
The pump motor drives the gear pump, which generates the pressure for the Shiftmatic 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 Volkswagen.
Pump Relay – Volkswagen Shiftmatic
The electromagnetic relay is responsible to turn on / off the hydraulic pump of the Volkswagen Shiftmatic system. A broken relay causes the pump to fail priming. Without hydraulic pressure, the system cannot engage the gears or clutch.
This is not an original part, but an OE part.
Selection Solenoid Valve – Volkswagen Crafter Shiftmatic
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 vehicle will refuse to go into one or more gears.
We offer a brand new spare part.
Shift Solenoid Valve – Volkswagen Crafter Shiftmatic
The shift solenoid valves (marked with “PPV”) are responsible for changing the gears of the Shiftmatic system. There are two of these valves on the hydraulic unit and together with the selection solenoid valve, they operate the shift actuator. If one of the valves is faulty, the car will refuse to go into one or more gears.
We offer a brand new spare part.
Solenoid Valve Seal Kit – Volkswagen Crafter Shiftmatic
- Seal kit for the solenoid valves
- Includes seals for all four valves
- Solution to eliminate internal leaks
Transmission Speed Sensor – Volkswagen Shiftmatic
This sensor provides the speed signal of the transmission input shaft. The speed signal is required by the control unit to control the transmission system, adjusting properly the shaft speeds before engaging and disengaging the different gears.
