	Remove/install
1	Remove bracket for engine management control unit (MCM)		AR07.08-P-7016MNM
		: Only install upper engine cover after the leak test.
2	Remove coolant expansion reservoir for low-temperature circuit upwards out of the elastomer bearings and place with attached lines to one side		AR09.41-P-0001MNM
3	Relieve fuel pressure over diagnostic socket		AR07.03-P-1460-01MNL
		Dust protection cap to service connection	*BA07.03-P-1005-01H
		Pressure hose	Fig 3
4	Release and disconnect electrical connector on right fuel pressure and temperature sensor (B42/1)
5	Thoroughly clean rail in area of right fuel pressure and temperature sensor (B42/1)	Absolute cleanliness is essential when working on the high-pressure fuel circuit. Only lint-free cleaning cloths may be used. Damage will occur otherwise on the high-pressure fuel circuit.
		Assembly cleaner	*BR00.45-Z-1028-04A
6	Cover connecting point of right fuel pressure and temperature sensor (B42/1) with suitable rag and carefully and slightly loosen right fuel pressure and temperature sensor (B42/1)	No fuel should flow over the engine. Damage will occur otherwise.
		Wear oil-resistant, fiber-free gloves lined with rubber.

		Box wrench attachment, 27_mm	Fig 2
7	Remove right fuel pressure and temperature sensor (B42/1)	: Use new right fuel pressure and temperature sensor (B42/1), since the right fuel pressure and temperature sensor (B42/1) is only designed to be screwed in once. Leaks can occur otherwise.
		Collect exuded fuel using a suitable absorbent rag.
		Box wrench attachment, 27_mm	Fig 2
8	Install in the reverse order
9	Read out and erase fault memory

	Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running.	Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts.	AS00.00-Z-0005-01A
11	Perform an engine test run and check engine for proper operation and leaktightness
12	Install upper engine cover
