	Remove
1	Unscrew valve cap (1).
2	Detach tire.		AR40.10-P-1030XG
3	Unscrew valve nut (2) from valve body (3).
4	Remove tire pressure sensor (A69/1, A69/2, A69/3, A69/4) with valve body (3) from disk wheel.
5	Remove seal (4) and hoist ring (5) from valve body (3).
6	Remove valve body (3) from tire pressure sensor (A69/1, A69/2, A69/3, A69/4).	When reusing tire pressure sensor (A69/1, A69/2, A69/3, A69/4).
	Clean
7	Clean tire pressure sensor (A69/1, A69/2, A69/3, A69/4).	When reusing tire pressure sensor (A69/1, A69/2, A69/3, A69/4). Only remove contamination using a clean, lint-free cloth and do not use any compressed air or solvent or cleaner. Otherwise the tire pressure sensor (A69/1, A69/2, A69/3, A69/4) will be damaged. Reuse tire pressure sensor (A69/1, A69/2, A69/3, A69/4) even after using TIREFIT tire sealant.
8	Clean disk wheel in area of valve bore.
	Install
9	Replace valve body (3) and valve element (6).	When reusing tire pressure sensor (A69/1, A69/2, A69/3, A69/4). Insert square of valve body (3) into guide at tire pressure sensor (A69/1, A69/2, A69/3, A69/4) so that this is fixed in its position.
10	Slide hoist ring (5) and seal (4) onto valve body (3).	Observe installation position (see arrow). The centering cone on the hoist ring (5) must sit correctly in the contour of the tire pressure sensor (A69/1, A69/2, A69/3, A69/4).
11	Insert valve body (3) with freely moving tire pressure sensor (A69/1, A69/2, A69/3, A69/4) from inside to outside into valve bore of disk wheel.
12	Tighten valve nut (2) to valve body (3).	When tightening the valve nut (2), gently press tire pressure sensor (A69/1, A69/2, A69/3, A69/4) into drop center and in the direction of the disk wheel valve bore. Nut to valve	*BA40.15-P-1001-01G
13	Mount tire.		AR40.10-P-1030XG
14	Screw on valve cap (1).	Only use plastic valve caps (1). Otherwise corrosion damage may occur.
15	Restart tire pressure monitoring system.		AR54.30-P-1001-01XG
