Ignition system 1. Ignition coil connector 4-pin; 2. Bolt, 10 Nm; 3.3 pin plug connector; 4. Hall sensor: Hall sensor "G40" (cylinder bank 1); Hall sensor 3 "G300" (cylinder bank 1); Hall sensor 2 "G163" (cylinder bank 2); Hall sensor 4 "G301" (cylinder bank 2); 5. Sealing ring. Replace if damaged. Lubricate with clean oil; 6. Bolt, 20 Nm; 7. Knock sensors. The mating surface between the knock sensor and the cylinder block must be free of corrosion, dirt and grease. Knock sensor 1 "G61" (cylinder bank 1). Knock Sensor 2 "G66" (cylinder bank 1); 8. Spark plug. Remove and install using spark plug wrench "3122 B", 30 Nm; 9. Ignition coil. Ignition coil 1 with output stage "N70"; Ignition coil 2 with output stage "N127"; Ignition coil 3 with output stage "N₂91"; Ignition coil 4 with output stage "N₂92"; Ignition coil 5 with output stage "N323"; Ignition coil 6 with output stage "N324". For removal use puller "T40039"
Removal ignition coils
Removing the ignition coils of cylinder bank 1: For ignition coil of cylinder 1 only: remove the lower part of the air filter housing. For ignition coils of cylinders 2 and 3: remove the air duct hose (open the hose clamp "3" and release the clamps "arrows").
Unscrew the ignition coil wiring harness bolts. Unlock the electrical connectors and remove them simultaneously from the ignition coils. Remove the ignition coils from the spark plug sockets using the "T40039" puller.
Removing the ignition coils of cylinder bank 2: Unscrew the coolant expansion tank "arrows". Disconnect the plug connector of the low coolant level indicator sensor "F66" from below on the coolant expansion tank and move the expansion tank with connected coolant hoses "1,2" and "3" to the side.
Unscrew the "arrow" bolts.

Verification data
| Idle speed (not regulated) | |
| Ignition timing | Not installed, confirmed used |
| Ignition system | Ignition system with 8 separately located ignition coils (with integrated output stages), which are placed directly on the spark plugs through the spark plug tip |
| Cylinder firing order | 1 "5 "3-6" 2" 4 |
Remove the ignition coil using the "T40039" puller by approximately 30 mm from the spark plug sockets. Unlock the electrical connectors and remove them simultaneously from the ignition coils.
Installation
Insert all ignition coils into the spark plug sockets without any effort. Align the ignition coils with the connectors and simultaneously place all connectors on the coils. Use your hand to press the ignition coils evenly against the spark plugs (do not use percussion instruments). Installation in reverse order. Ignition coil wiring on the cylinder head housing: 5 Nm.
