	Remove/install
	Risk of death caused by contact with parts conducting high voltages.	Do not touch parts which conduct high voltages. Persons who wear electronic implants (e.g. heart pacemakers) should never perform any work on the ignition system	AS15.10-Z-0001-01A
	Risk of injury caused by fingers being pinched or crushed when removing, installing or aligning hoods, doors, trunk lids, liftgates or sliding roof	Keep body parts and limbs well clear of moving parts.	AS00.00-Z-0011-01A
	Notes on avoiding damage to ignition system		AH15.10-P-0002-01L
1	Remove engine trim panel	Engine 275.95	AR01.10-P-2405LA
1	Remove engine trim panel	Engine 275.98	AR01.10-P-2405IM
2	Remove left or right air filter housing (1)	Model 215, 216, 220, 221, 230 without code (P99) Special Model "AMG Black Series"	AR09.10-P-1150LA
3	Remove left or right charge air duct (2) upstream of charge air cooler (3) on turbocharger		*BA09.41-P-1001-02B
4	Remove charge air duct (4) downstream charge air cooler (3) at left or right charge air cooler (3)		AR09.50-P-8680H
5	Slacken left or right charge air cooler (3), to do so unscrew bolts (6)		*BA09.41-P-1001-03A
6	Disconnect pneumatic line (5a) on charge air cooler (3).	When removing the ECI ignition module, right cylinder bank (N92/1). Check pneumatic line (5a) and hose clamp for damage and replace if required.
7	Remove pneumatic line (5c) at charge air cooler (3).	When removing the ECI ignition module, right cylinder bank (N92/1). Install new cable ties.
8	Disconnect electrical connector at pressure sensor upstream of throttle valve actuator (B28/6) and remove	When removing ECI ignition module, right cylinder bank (N92/1). The pneumatic line (5b) is bonded with the support to charge air cooler (3). This combination must not be separated, otherwise leakage may occur.
