Installing the ignition coils of cylinders 1 and 2
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2023 BMW M5, 2022 BMW M5, 2021 BMW M5, 2020 BMW M5, and 2019 BMW M5. However, it is still accessible from the selected car via links, so may be relevant.
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.
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:
The description is provided only at one component. The procedure is the same for all other components.
- Before installing the ignition coils: Fuse the spark plug shafts (2)
out with an air gun (1)
.
- Position the ignition coil and gently push it to the stop, if necessary by twisting it back and forth slightly.
If necessary, the cable conduit on the heat shield must be pushed upwards slightly.
- Push connector (1) onto the ignition coil with the connector fastener (2) open.
- Carefully close the connector fastener (2)
.
On closing locking lever, the connector (1) must lie on counter piece almost gap-free. In the process, the crank webs of the locking lever are positioned inside the counter piece.
- Ensure that no cables are crushed or damaged.
The connector fastener must snap into place without great effort.
- Repair damaged cables.
- Check the anti-twist lock (1)
.
The rubber seal of the ignition coil must completely enclose the opening for the spark plug on the cylinder head cover.
