	000 588 03 82 00 Filling unit	Before each emptying procedure, the shutoff valves (6) of the respective suspension strut (1, 4) must be screwed in up to the end stop (arrows A). Otherwise the suspension strut (1, 4) will be irreparably damaged. The hydraulic pressure in the suspension strut (1, 4) can only be retained by closing the shutoff valves (6). It is not possible to fill the suspension strut (1, 4).	WS32.00-P-0032B
		Screw, shutoff valve to suspension strut If pressure release using diagnostic system is not possible, ↓ release pressure manually.	*BA32.50-P-1008-04B
		Manually reduce pressure in hydraulic system of electrohydraulic suspension if shutoff valves (6) are intact	AR32.50-P-0015-01S
		Screw, shutoff valve to suspension strut If shutoff valves (6) on suspension strut (1, 4) cannot be closed, ↓ release pressure in system and replace suspension strut (1, 4).	*BA32.50-P-1008-04B
		Manually reduce pressure in hydraulic system of electrohydraulic suspension if shutoff valves (6) are defective Remove suspension strut (1).	AR32.50-P-0015-02S
