	Removing
1.1	Open reservoir cap (30g) and extract oil from reservoir of power steering pump.	Model 129, 163, 170, 202, 208, 211, 220 Model 210 without Adaptive damping system (ADS) with level control, code 216b.
		Hand pump	Figure
1.2	Clamp off feed line from reservoir	Model 210 with Adaptive damping system (ADS) with level control, code 216b.
		Clamping device	Fig 6
2	Detach high pressure expansion hose (30i) on power steering pump	On vehicles with tandem pump the testing unit must not be connected to the pressure oil pump for adaptive damping system (ADS) with level control, code 216b.
3	Attach connection fitting (038a) to high-pressure expansion hose (30i).	Special tool 210 589 09 63 00 was replaced by special tool 215 589 01 63 00. Both special tools can be used for carrying out the test.
		Connection fitting	Fig 7
4	Attach connection fitting (038b) to power steering pump	Special tool 210 589 09 63 00 was replaced by special tool 215 589 01 63 00. Both special tools can be used for carrying out the test.
		Connection fitting	Fig 7
5	Connect testing unit (039) between the connection fitting (038a) and connection fitting (038b)	Tester	Fig 8
6	Remove clamp from feed line from reservoir	Model 210 with adaptive damping system (ADS) with level control, code 216b.
7	Fill supply reservoir
	Check and correct power steering fluid level		AP46.00-P-4611BB
	Risk of accident from vehicle starting off by itself when engine running. Risk of injury from bruises and burns if you hold your hand into engine when it is started or when it is running.	Secure vehicle to prevent it from moving by itself. Wear closed and snug-fitting work clothes. Do not grasp hot or rotating parts.	AS00.00-Z-0005-01A
8	Start engine
9	Increase engine speed to approx. 1000 rpm
	Checking
10	Close throttle cock (039a) and check maximum operating pressure.	Only carry out the test briefly so that the oil temperature does not rise unacceptably.
