	Remove/install
1	Place front wheels in straight-ahead position
2	Drain left or right suspension strut (40) using diagnostic system
			AD00.00-P-2000-04A
		The suspension strut (40) must be filled according to specification. Otherwise, the suspension strut (40) may suffer initial damage and malfunction later at a later stage.
3.1	Switch off ignition and remove transmitter key from electronic ignition lock control unit	MODEL 212 with CODE 489 (AIRMATIC) without CODE 889 (KEYLESS-GO) MODEL 218 with CODE 489 (AIRMATIC) without CODE 889 (KEYLESS-GO)
3.2	Switch off ignition and remove transmitter key or KEYLESS-GO start/stop button from electronic ignition lock control unit	MODEL 212 with CODE 489 (AIRMATIC) with CODE 889 (KEYLESS-GO) MODEL 218 with CODE 489 (AIRMATIC) with CODE 889 (KEYLESS-GO)
4	Remove cover (10) from left or right suspension strut (40)
5	Detach pressure line (40a) from suspension strut (40).	When reinstalling the old suspension strut (40), make sure that the pressure line (40a) is carefully screwed on to the plastic thread. Otherwise, if not screwed on properly, the plastic thread will be damaged thereby causing irreparable damage to the suspension strut (40). Seal pressure line (40a) with blind plugs during repair work. When replacing the suspension strut (40): ↓ Detach old pressure line connection to the pressure line (40a). To do this break open the clamping ring, detach pressure line connection and insert the pressure line (40a) up to the marking in the new pressure line connection. Pull back pressure line (40a) a short distance so that the peripheral retaining edges in the inside of the clamping ring engage in the line outer surface. If pressure line (40a) or pressure line connection is damaged or leaky: ↓ Repair pressure line (40a) or damaged pressure line connection.
