Pressure Accumulator – Volkswagen Crafter Shiftmatic
The pressure accumulator is responsible for storing the pressure of the hydraulic system for later access by the actuators. This piston type accumulator has two cells: one cell storing the hydraulic fluid and one cell containing a nitrogen gas filling which creates the counterpressure. Both cells are separated by a moving piston. Typical symptoms of a faulty pressure accumulator are frequent and short pump cycles. If there is no more preload pressure left in the accumulator, the pump runs every few seconds, which ultimately leads to consequential damage to the pump motor. Along with the pump motor, a faulty pressure accumulator is one of the most common causes of pressure build-up issues and is one of the few wear parts in the system that should be regularly checked and replaced if necessary.
We offer a brand-new replacement accumulator.
Pressure Sensor – Volkswagen Shiftmatic
The pressure sensor is responsible for detecting the hydraulic pressure in the accumulator of the Shiftmatic system. This is an original and brand-new spare part.
