		Dust protection cap to service connection	*BA07.03-P-1005-01H
		Pressure hose	Fig 3
3	Release and disconnect electrical connector at right fuel pressure and temperature sensor (B42/1)
4	Clean rail in the area of right fuel pressure and temperature sensor (B42/1)	Absolute cleanliness is essential when working on the high-pressure fuel circuit. Use only lint-free cleaning cloths Damage will occur otherwise on the high-pressure fuel circuit. Assembly cleaner	*BR00.45-Z-1028-04A
5	Cover area around right fuel pressure and temperature sensor (B42/1) with suitable rags and carefully slightly release right fuel pressure and temperature sensor (B42/1)	Wear oil-resistant, fiber-free gloves lined with rubber. Box wrench attachment, 27 mm	Fig 2
6	Unscrew right fuel pressure and temperature sensor (B42/1) from rail and remove	Use new right fuel pressure and temperature sensor (B42/1), as right fuel pressure and temperature sensor (B42/1) is only designed to be screwed on once. Leaks can occur otherwise.
		Collect exuded fuel using a suitable absorbent rag.
7	Install in the reverse order
