Installing the ignition coils

NOTE: RISK OF DAMAGE
Damage to the ignition coil.
The silicone hose of the ignition coil must not be contaminated by fuel as this can lead to failure of the ignition coil.

When working on the fuel system, cover the ignition coils with suitable materials and remove where required.
Do not oil or grease the silicone tube of the spark plug socket. Do not use any protection or maintenance products (e.g. silicone spray, rubber care products, rust remover, etc.).

NOTE: RISK OF DAMAGE
Damage to the catalytic converter due to misfiring.
An incorrectly mounted ignition coil can loosen during engine operation, thereby causing misfiring.

Ensure that the sealing lip fits correctly on the ignition coil so that it can seal correctly. Do not crush the sealing lip.

NOTE: The description is provided only at one component. The procedure is the same for all other components.

Position the ignition coil and push it to the stop position with little effort.
If necessary, turn the ignition coil back and forth gently.
Check anti-twist lock.
Check, whether the rubber seal of the ignition coil completely encloses the opening for the spark plug on the cylinder head cover.
Push connector (1) onto the ignition coil with the connector fastener (2) open.
Carefully close the connector fastener (2) in the direction of the arrow.
The connector fastener must snap into place at the correct position without great effort.
