 	Remove/install
1	Remove top cylinder head cover trim.		AR01.20-P-5015MFE
		 Installation: Only install upper engine cover after the leak test.
2	Disconnect ground line of on-board electrical system battery (G1).		AR54.10-P-0003MFA
3	Remove engine air intake duct downstream of air filter housing.		AR09.10-P-8130MFE
4	Disconnect engine wiring harness to remove low-pressure lines (7).		AR15.18-P-1121-01MFE
		 Dismantling tool	*000589956300
5	Remove screws (1, 4).	 Bolt, fuel line to valve housing/fuel line holder	*BA47.25-P-1001-01K
		 Bolt, holder for fuel line to holder for high-pressure pump at rear	*BA47.25-P-1002-01K
6	Unclip electrical subharness from low-pressure lines (7) (arrows).	 Dismantling tool	*000589956300
7	Clamp off fuel lines (2, 5).	 Clamp	*000589403700
8	Clean low-pressure lines (7) in the area of the fuel lines (2, 5).	Assembly cleaner	*BR00.45-Z-1028-04A
9	Release click clamps (3), detach fuel lines (2) from the low-pressure lines (7), and capture escaping fuel with a suitable container.	 Installation: Install new click clamps (3).
		 Pliers for click clamps	*177589003700
10	Release and disconnect hose couplings of the fuel lines (5) from the high-pressure pump and capture escaping fuel with a suitable container.	 Ensure scrupulous cleanliness. No foreign objects or soiling may enter the connections of the high-pressure pump. The high-pressure pump will otherwise be damaged.
11	Seal openings on fuel lines (2, 5) and low-pressure lines (7) with suitable stop plugs.	 Record plug	*129589009100
12	Remove low-pressure lines (7) with connected fuel lines (5).	 Do not crush or kink or subject lines to tension. This would lead to damage to the lines and can impair their function.
13	Remove holder (8).	If new low-pressure lines (7) are installed.
		 Bolt, fuel line to valve housing/fuel line holder	*BA47.25-P-1001-01K
14	Release click clamps (6) and remove fuel lines (5).	If new low-pressure lines (7) are installed without fuel lines (5).
		 Collect fuel which runs out in a suitable container.
		 Installation: Install new click clamps(6).
		 Pliers for click clamps	*177589003700
15	Remove fuel pressure and temperature sensor (B4/25).	If new low-pressure lines (7) are installed.
