Installing the ignition coil of cylinder bank 2

Precondition

Ignition is switched off.

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.).
