ABC valve units repair and new parts

SYMPTOMS OF DAMAGE:

1. The vehicle sags on the front and / or rear axle.

2. The correct pressure supply with the ABC hydraulic pump is impaired (pressure fluctuations from 120 bar to 180 bar). For safety reasons, the suction throttle valve on the ABC pump is closed again and again to reduce pressure in order to prevent further damage. Possible error messages in white and red, ABC defect, please contact the workshop. If the drop is more than 63 mm, there is a red error message, attention, vehicle too low, please drive carefully, or even stop. Start the engine and shift the selector lever to D or R, the vehicle starts up again, provided the ABC hydraulic pump brings the required pressure.

Drives the vehicle no longer high lies, the mistake somewhere else.
