Perform initialization of DTR control unit after replacing steering angle sensor, added

Step 6

	Remove/install
	Steering angle sensor (N49) and steering column module (N80) form one component and can only be replaced together where necessary
1	Remove clock spring contact		AR46.10-P-0200TX
2.1	Remove bolt (1)	On vehicles up to 2.3.08 or without code (809) Model year 2009
2.2	Lift steering angle sensor (N49) over the guide pin	On vehicles as of 3.3.08 or with code (809) Model year 2009 Bolt (1) replaced by a guide pin.
3	Unclip retaining lugs (a) of steering column module (N80) from carrier plate (5)
4	Pull out steering angle sensor (N49) from carrier plate (5)	Check basic position of steering angle sensor (N49) (observe arrows on steering angle sensor (N49) and inner race (2). If the steering angle sensor (N49) twists, move the steering angle sensor (N49) into the center position before installing it again:
		To do so, carefully turn the inner race (2) of the steering angle sensor (N49) in a counterclockwise direction all the way to the limit stop.
		Turn inner race (2) of steering angle sensor (N49) lightly up to the limit stop, as otherwise it may be damaged.
		Finally, turn the inner race (2) through approx. two rotations in a clockwise direction, until the arrows on the steering angle sensor (N49) and inner race (2) line up.
5	Install in the reverse order
6	Perform initialization of DTR control unit with STAR DIAGNOSIS	After replacing steering angle sensor (N49) on vehicles with code (219) Distronic (DTR)
