3	Spray pressure line connections with leak detector spray	Cover objects (rear shelf, head restraints etc.) in the vicinity of the spraying area with a clean rag. Spray the following pressure line connections: Connections (4SP, 5VL, 6P, 7HR, 8HL, 9VR) on valve unit (Y36/6), connection (4SP) of compressor unit (A9/1), connection (4SP) on central reservoir (2), connections (5VL, 9VR) and areas of adhesive on front suspension struts (10), connections (7HR, 8HL) and areas of adhesive on rear suspension struts (11, 12). Wait for approx. 10 to 15 min after spraying the pressure line connections with leak detection spray. This allows smaller leaks to be detected (bubbles form). Larger leaks are visible immediately.
