1	Remove front seat (1) on passenger side		AR91.10-P-1000GZ
2	Unclip electrical line from right rear WSS sensor (weight sensing system) (B48/14) from circlips (arrow A and arrow B)	Do not damage electrical line on right rear WSS sensor (weight sensing system) (B48/14).
3	Disconnect electrical connector (4) from WSS control unit (weight sensing system) (N2/13) (arrow C)
4	Unscrew nut (3) and remove bolts (2)	Install bolt (2) only with associated left rear WSS sensor (weight sensing system) (B48/13) or right rear WSS sensor (weight sensing system) (B48/14). Lightly grease bolt (2) before installing and hold when tightening nut (3).
			*BA91.60-P-1011-01H
5	Remove bolts (5)		*BA91.60-P-1013-01H
6	Remove left rear WSS sensor (weight sensing system) (B48/13) or right rear WSS sensor (weight sensing system) (B48/14) together with installed bracket (6)	Never loosen or remove mount from left rear WSS sensor (weight sensing system) (B48/13) or right rear WSS sensor (weight sensing system) (B48/14)! This would render the left rear WSS sensor (weight sensing system) (B48/13) or right rear WSS sensor (weight sensing system) (B48/14) unusable
7	Check plastic bearing (7) for wear and replace if necessary	If required, remove retaining ring (8) and drive out plastic bearing with suitable tool. Install new plastic bearing by hand and fasten with circlip.
8	Install in the reverse order
9	Calibrate left front WSS sensor (weight sensing system) (B48/11), right front WSS sensor (weight sensing system) (B48/12), left rear WSS sensor (weight sensing system) (B48/13) and right rear WSS sensor (weight sensing system) (B48/14) with STAR diagnosis system.	Plates	Figure
	Connect STAR DIAGNOSIS and read out fault memory		AD00.00-P-2000-04A
