Removing
To pull off spark plugs, place T40039 on uppermost thick rib -arrow- of ignition coils with power output stages.
If lower ribs are used, these can be damaged
-- Remove engine cover. Refer to UPPER ENGINE COVER, REMOVING AND INSTALLING .
Spark plugs are located under ignition coils with power output stages.
-- Pull off the connector -1- with T10118 in direction of -arrow-.
It is necessary to pull off the connector so that afterwards the ignition coils with power output stages with connected wires can be set aside without disturbing the routing of the wiring!
-- Pull out all ignition coils with power output stages -1- upward using T40039.
Lines or connectors of ignition coils may remain connected when pulling out ignition coils with power output stages.
Note installation position of ignition coils with power output stages!
-- Set ignition coils with power output stages (with lines connected) carefully to the side.
Make sure wires are not kinked or damaged.
-- Remove spark plugs using 3122 B.
Installing
-- Screw in new spark plugs using 3122 B and tighten to 20 Nm.
-- Guide ignition coils with power output stages into cylinder head and align ignition coils to designated recesses of cylinder head cover.
-- Press ignition coils with power output stages on to spark plugs up to stop, they must engage audibly.
-- Press the connector onto the exhaust gas recirculation valve until it is noticeably engaged.
Make sure that wiring of ignition coils with power output stages is routed properly.
-- Install engine cover. Refer to UPPER ENGINE COVER, REMOVING AND INSTALLING .

-- Remove both bolts -1-.
-- Pull all ignition coils approximately 30 mm out of cylinder head in direction of arrow using T40039.
-- Push connector in direction of ignition coils with power output stages, press catch down by hand and disconnect connectors -arrows-.
-- Remove spark plugs using 3122 B.
Plug designation and torque specification. Refer to IGNITION SYSTEM COMPONENT OVERVIEW
Observe waste disposal regulations!
