1	Detach tires	Replace tires Model 463 (except 463.234/255/274) up to model year 2019 with code 475 (Tire pressure monitor (TPM)) with code 979 (Special protection MB Guard) except code ZQ0 (G 500 4x42 ) with Rodgard run flat system	AR40.10-P-1030PM
		Replace tires Model 463.234 up to model year 2019 with code 475 (Tire pressure monitor (TPM)) with code ZQ0 (G 500 4x42 ) Model 463.255 up to model year 2019 with code 475 (Tire pressure monitor (TPM)) with code MUK2 (USA or Canada vehicle model designation) with code ZQ0 (G 500 4x42 ) Model 463.274 up to model year 2019 with code 475 (Tire pressure monitor (TPM)) with code LQ0 (G650 Landaulet)	AR40.10-P-1030GWX
2	Unscrew collar nut (2) from valve body (3) and remove
3	Remove tire pressure sensor (A69/1 to A69/4) with valve body (3) from disk wheel
4	Remove seal (5) and support ring (6) from valve body (3)
5	Remove valve body (3) of tire pressure sensor (A69/1 to A69/4)	When reusing the tire pressure sensor (A69/1 to A69/4).
	Clean
6	Clean tire pressure sensor (A69/1 to A69/4)	When reusing the tire pressure sensor (A69/1 to A69/4). Only remove dirt with a clean, lint-free cloth. Do not use any compressed air, solvent and cleaner. The tire pressure sensor (A69/1 to A69/4) can also be reused after using TIREFIT tire sealant.
7	Clean the disk wheel in the area of the valve bore
	Check
8	Carry out visual check of tire pressure sensor (A69/1 to A69/4)	Replace tire pressure sensor (A69/1 to A69/4) if damage is apparent.
9	Check disk wheel for damage in the area of the valve bore
	Install
10	Detach label (4) with identification number (I) of tire pressure sensor (A69/1 to A69/4) and affix to maintenance booklet	When replacing the tire pressure sensor (A69/1 to A69/4).
11	Replace valve body (3) and valve element (7)	When reusing the tire pressure sensor (A69/1 to A69/4). Insert square of valve body (3) into guide at tire pressure sensor (A69/1 to A69/4) so that this is fixed into position. Observe transmission frequency (F) of tire pressure sensor (A69/1 to A69/4): Vehicles with 315 MHz Vehicles with 433 MHz
12	Mount support ring (6) and seal (5) on valve body	The cone on the support ring (6) must sit correctly in the contour of the tire pressure sensor (A69/1 to A69/4).
13	Insert valve body (3) with free-moving tire pressure sensor (A69/1 to A69/4) from inside to outside into valve bore of disk wheel
14	Tighten collar nut (2) on valve body (3)	Take into account correct collar nut design for steel wheels or light alloy wheels. When tightening the collar nut (2), lightly press tire pressure sensor (A69/1 to A69/4) into drop center and in direction of valve bore of disk wheel. Nut to valve	*BA40.15-P-1001-01G
15	Mount tire	Model 463 (except 463.234/255/274) up to model year 2019 with code 475 (Tire pressure monitor (TPM)) with code 979 (Special protection MB Guard) except code ZQ0 (G 500 4x42 ) with Rodgard run flat system	AR40.10-P-1030PM
		Replace tires Model 463.234 up to model year 2019 with code 475 (Tire pressure monitor (TPM)) with code ZQ0 (G 500 4x42 ) Model 463.255 up to model year 2019 with code 475 (Tire pressure monitor (TPM)) with code MUK2 (USA or Canada vehicle model designation) with code ZQ0 (G 500 4x42 ) Model 463.274 up to model year 2019 with code 475 (Tire pressure monitor (TPM)) with code LQ0 (G650 Landaulet)	AR40.10-P-1030GWX
16	Using Star Diagnosis, code identification number (I) of tire pressure sensor (A69/1, to A69/4) and specified tire pressure in tire pressure monitor control unit (N88).	When replacing the tire pressure sensor (A69/1 to A69/4). Process all steps under: "Control units" -"Chassis" - "TPM tire pressure monitor" -"Commissioning" - "Commissioning with manual adjustment of new control unit".
17	Activate the tire pressure monitoring system	When replacing the tire pressure sensor (A69/1 to A69/4).
