Audi A4 Ignition Coil

The Audi A4 Ignition Coil is an electronic device that transforms the 12-volt supply of its car battery into tens of thousands of volts required by the spark plugs to make the engine run. A heavy primary winding is stacked in an enclosed epoxy housing and the magnetic field is formed around an iron core, and a fine secondary winding consisting of thousands of turns then encloses the collapsing field and this increases the voltage to about 15,000-40,000 volts. Earlier Audi vehicles had a single Ignition Coil and a distributor, which was a long-wire circuit on which the surge was passed to each cylinder. With the advancement of electronics, waste-spark coil packs became available, which allowed one Ignition Coil to have two cylinders fired simultaneously, the second spark harmlessly hitting an exhaust stroke. The majority of current Audi engines are now using coil-on-plug or near-plug implementations, with every Ignition Coil positioned directly at the top or adjacent to a spark plug to cut energy waste and provide the ECU greater timing resolution. Throughout the generations of the A4, these measures have given it an easier idle, faster starts and improved fuel economy. Nevertheless, an Audi Ignition Coil has to be able to connect the low and high circuits, and heat, cracks, or corrosion in an Audi engine bay may cause a weakening in output and turn on the check-engine light.

Disconnect the electrical connectors from any components with harnesses obstructing access, then set the harnesses aside. Remove the fasteners securing the clips for the ignition coil harness, disconnect all three electrical connectors from the coils, and ensure all three connectors are disconnected to pull the harness back far enough for the coil to clear the connector.
