The pressure control valve can only be replaced if:
- Pressure control valve
- Socket insert
- it was damaged during removal and installation,
- it was damaged while disassembling and assembling the air-spring strut,
- the sealing ring is faulty,
- it does not allow any more air to come out (valve jammed).
