Volkswagen Jetta Ignition Coil converts the low voltage of the battery into a high voltage that jumps each spark plug gap and allows the fuel to ignite as soon as the key is pressed. Older models applied one coil and mechanical breaker points and a capacitor, but new designs in Volkswagen cars incorporate a solid-state transistor within each Ignition Coil and usually place one unit per two cylinders, a design known as wasted spark, minimizing high-tension wiring and providing increased reliability. The owners of the well renowned Jetta can use an ohmmeter to check the health of the coils, expecting about 0.5 to 2 ohms on the primary winding and 8,000 to 20,000 ohms on the secondary; values that are far outside these ranges are an indication of a problem. The federal regulations recommend changing coils after every 24,000 miles or two years, but in most Volkswagen engines, with high-strength coils, replacement is possible after 100,000 miles as long as the heat and voltage remain within limits. Hot spark plugs not only increase temperatures in the chambers but also compel the Ignition Coil to produce additional voltage, a factor that hastens the process of breakdown, misfiring and improper use of fuel. Single-tower or compact coil-on-plug, all the Ignition Coils have the same purpose, to amplify voltage and have your Volkswagen purring like a kitten.
