1	Remove engine compartment lining	 Only on the right-hand side of the vehicle for testing the AIRmatic compressor unit (A9/1)	AR61.20-P-1105M
2	Remove part of the wheel house inner panel in front fender	 Only on the right-hand side of the vehicle for testing the level control valve unit (Y36/6)
3	Spray the pressure line connections (1VL, 2VR, 3HL, 4HR, 5SP,P) of the level control valve unit (Y36/6), the pressure line connection of the AIRmatic compressor unit (A9/1) and the pressure line connection (42a) of the central reservoir (42) with leak detecting spray	 Wait for approx. 10-15 minutes after spraying. This means that minor leaks can be recognized (forming a white cap). Severe leaks are evident immediately.
		 Use leak detecting spray
4	Spray the area of the casting compound and pressure line connections (40a, 41a) on the spring struts (40, 41) with leak detecting spray	 Wait for approx. 10-15 minutes after spraying. This means that minor leaks can be recognized (forming a foam crown). Severe leaks are evident immediately.
