 	Remove/install
1	Turn key in electronic ignition switch control unit to position "0"
2	Open engine hood		AR88.40-P-1000V
3	Detach engine air intake duct (1) upstream of air filter
4	Disconnect electrical connector (2) at throttle valve actuator (M16/6)
5	Detach pressure connection (3) from throttle valve actuator (M16/6), for this step loosen hose clamp (4) and unscrew bolts (5)	 Installation: Do not coat with grease openings of pressure connection (3). During pressure buildup of compressor, the pressure connection (3) from the throttle valve actuator (M16/6) is released.
			*BA09.41-P-1004-02A
6	Detach gasket (6) from throttle valve actuator (M16/6)
7	Remove bolts (7) and take out throttle valve actuator (M16/6)	 Installation: Observe guide lugs at throttle valve actuator (M16/6), otherwise this can cause damage to the sealing ring (8) due to leakage.
		 Installation: Replace seal (8).
			*BA30.20-P-1002-01C
8	Install in the reverse order
9	Connect STAR DIAGNOSIS, read out fault memory and erase if necessary
