	Inspecting
	Ignition: OFF
1	Inspect ease of operation and condition of Bowden cable (30) and throttle control rods	If necessary replace
2	Detach connecting rod (2) at one side
3	Inspect CTP stop	Crank lever must be resting against CTP stop (arrow) of electronic accelerator (EA) actuator (M16/1) (stop audible)
4	Attach connecting rod (2) at one side
	Adjusting control pressure Bowden cable (11)
5.1	Turn connecting rod (2)	Left-hand steering For this step, the tips at the crank lever (8) and lever (7) must be positioned exactly opposite when control pressure Bowden cable is attached. Lock nuts at ball sockets	*BE30.10-P-1001-01C
	Crank lever of right-hand steering/left-hand steering standardized		BT30.10-P-0001-01A
5.2	Turn connecting rod	Right-hand steering	AR30.10-P-1010-01E
	Crank lever of right-hand steering/left-hand steering standardized		BT30.10-P-0001-01A
	Setting WOT
6	Ignition: ON	The ignition must be switched on otherwise the throttle valve does not move to wide open throttle (WOT)
7	With engine switched off, depress accelerator pedal (24) from inside the car as far as the stop at kickdown switch (S16/7) (do not operate kickdown switch!)	Crank lever (1) must be resting against WOT stop of electronic accelerator (EA) actuator (M16/1) (stop audible); alter position of adjusting nut (29), if necessary. If the throttle control linkage is operated from the engine compartment when the ignition is switched on, the EA control module switches to emergency running mode and a fault is stored in the fault memory. Read fault memory
	Setting CTP
8	Inspect CTP stop	Driver spring (26) at Bowden cable must be making contact free of play; alter position with adjusting bolt (32), if necessary
9	Grease Bowden cable (30) with corrosion protection grease between end pieces and guide piece		*BR00.45-Z-1006-06A
