General instructions for working on the ignition system
Follow all necessary instructions after connecting the battery. A voltage of at least 11.5 V is required for the operation of electrical components without failure. After completing work, interrogate the fault memory of the engine control unit, delete all fault records that may have arisen as a result of checks and repairs. After clearing the fault memory, create a code readiness - Vehicle diagnosis, measurement and information system VAS 5051 "Guided function". If, after troubleshooting, repairing or checking components, the engine starts and runs only for a short time and stalls, then the engine control unit is blocked by the immobilizer. In this case, it may be necessary to adapt the engine control unit - Vehicle diagnosis, measurement and information system VAS 5051 "Guided Functions".
- 1 - Knock sensor 1-G61-, on the cylinder head in front under the intake manifold. To remove, it is necessary to dismantle the cooling system pump, the contacts are gold-plated
- 2 - 20 Nm, the tightening torque affects the operation of the knock sensor
- 3 - Ignition coil with output stage - (N70, N127, N291, N292) -
- 4 - Spark plug, 25 Nm, remove and install with spark plug wrench -3122 V-
- 5 - O-ring, replace
- 6 - Engine speed sender -G28-, in cylinder block at front bottom left, next to primary oil separator
- 7 - 10 Nm
- 8 - Hall sender -G40-, in cylinder head cover, gold-plated contacts
Removal and installation of ignition coils with output stages
Instruction: To remove the ignition coils with output stages from the spark plugs, place puller -T40039- at the upper thick rib -arrow- of the coil. If you use the lower ribs of the coil, they can be damaged.
Using puller -T40039-, pull ignition coils approx. 30 mm out of spark plug sockets.
Release connectors and remove all connectors from ignition coils -arrows- at the same time.
Installation of ignition coils with output stages
Insert the ignition coils into the sockets of the candles without force. Align ignition coils with connectors -arrows- and connect all connectors to ignition coils at the same time. Press the ignition coils onto the spark plugs evenly by hand.
