Install the ignition coils of cylinder bank 2
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.

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
Electrostatic discharge.
Damage to or destruction of electrical components.

Damage to or destruction of electrical components.
- Leave the electrical components in their original packaging until they are being installed. Only use the original packaging for returning the product. Always package removed components straight away.
- Read and comply with user information on using the associated special tool 12 7 060.
- Only tap the housings of electrical components. Do not tap pins or multi-pin connectors directly.
- Wear electrically conductive clothing and antistatic shoes (with ESD symbol).
- For additional information see: 61 35... NOTES ON ESD (ELECTROSTATIC DISCHARGE) PROTECTION
- Position the ignition coils of cylinder bank 2 (1).
- Tighten the screws (2).TIGHTENING TORQUE SPECIFICATIONS

- Ensure that the sealing lip fits correctly on the ignition coil so that it can seal correctly. Do not crush the sealing lip.
- Position the ignition coil and gently push it to the stop, if necessary by twisting it back and forth slightly.
- 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.
