Dynamic Ride Control (DRC), Draining And Filling: Filling
-- Open the needle valve -B- approximately 2 turns and let the oil run out of the oil reservoir on the :VAS 6544 into the evacuated DRC system.
Oil flows from the reservoir into the connected DRC system. This is shown by the decreasing oil level in the oil reservoir. Depending on the amount of oil remaining after extraction, the procedure may take several minutes. As the system fills up, the oil level goes down slower. If the level of the oil no longer moves, the first step of the filling process is complete.
-- Close the needle valve -B-.
-- Open the valve -A- and fill the DRC system to 22 bar by pumping the lever on the hand pump -1- several times.
While filling, make sure the oil reservoir on the :VAS 6544 does not run dry; fill with reservoir with new oil if necessary.
- When a pressure of 22 bar is reached, close the valve -A- and do not pump the hand pump lever any more.
Exceeding the maximum pressure of 22 bar does not improve the filling process. Caution! Danger of damaging DRC system components as well as the :VAS 6544 .
If the pressure does not reach 22 bar or if it continually drops, check all connections for damage or leaks. If no issues are found on the outside, the gas reservoir to the pressure clamps on the piston on the inside of the central valve is leaking. Replace the central valve.
-- Open the needle valve -B- slightly and let the pressure drop to 20 bar.
- Close the valve -B- when the indicator on the pressure manometer reaches the 20 bar marking.
The 16-bar graduation line on the scale is colored in green depending and the version and model of the pressure gauge. The marking has no meaning for this procedure.
DRC system is filled.
-- Disconnect the fill line and quick-release fastener on the :VAS 6544 ) DYNAMIC RIDE CONTROL (DRC), DRAINING AND FILLING - Fill Lines with Quick-Release Fastener from the rear and front suction/fill valve.
-- Mount the rear wheel.
-- Install the dust cap on the rear and front suction/fill valve.
