2.0L - Ignition/glow Plug System - Engine Code(s): Bpy: Other Volkswagen Eos I

SAFETY PRECAUTIONS

To reduce the risk of personal injury and/or damage to the fuel injection and ignition system, always observe the following

1. Do not touch or disconnect the ignition coils with power output stages when the engine is running or turning at starting speed.
2. Only disconnect and reconnect wires for the injection and ignition system, including test leads, when the ignition is turned off.

If special testing equipment is required during a road test, note the following

1. Test and measuring instruments must be secured to the rear seat and operated by a second person from this location.

If the vehicle is involved in a collision while the testing and measuring equipment is operated from the front passenger seat, the person sitting in that seat could be seriously injured when the airbag deploys.

IGNITION SYSTEM

1. For trouble free operation of the electrical components a voltage of at least 11.5 volts is necessary.
2. After completing the work, check the Engine Control Module (ECM) Diagnostic Trouble Code (DTC) memory. Erase all DTC entries which may have been caused by tests and repairs. Generate a readiness code if the DTC memory was erased. Refer to "Guided Function" in the vehicle diagnosis, testing and information system VAS 5051.
3. If the engine only starts briefly and then shuts off again after troubleshooting, repair or checking of the components, it may be that the immobilizer is blocking the ECM. The module must then be adapted, as necessary. Refer to "Guided Functions" in the vehicle diagnosis, testing and information system VAS 5051.

SPARK PLUG TECHNICAL DATA

IGNITION COIL WITH POWER OUTPUT STAGE

Special tools and workshop equipment required

1. Ignition Coil Puller -T40039

Removing

Note. Follow all safety precautions. Refer to SAFETY PRECAUTIONS . Ignition components overview. Refer to IGNITION COMPONENTS OVERVIEW . To pull out the spark plugs, place the ignition coil puller -T40039- on the topmost thick rib -arrow- of the ignition coil with power output stage. The lower ribs may be damaged if they are used.

Release the connectors and pull all connectors simultaneously off from the ignition coils.

Scheme 3

Remove all ignition coils from the spark plugs using the ignition coil puller -T40039-.

Scheme 4

INSTALLING

Note. The ignition coil with power output stage must be greased using lubricating paste -G 052 141 A2- to install new spark plugs. This prevents the sealing hose on the ignition coil from sticking on the spark plug. The lubricating paste must spread onto the spark pug when installing the ignition coil. New ignition coils with power output stages are already greased when delivered.

Apply a thin bead of lubricating paste -G 052 141 A2- around the ignition sealing hose -arrow-. The bead must be 1 to 2 mm thick.

Scheme 5

Insert the ignition coils loosely onto the spark plug shaft.

Align the ignition coils to the connectors and then connect all of the connectors simultaneously onto the ignition coils.

Scheme 6

Press the ignition coils evenly onto the spark plugs by hand.
