Audi Ignition Coil Failure Symptoms in the Bay Area, CA
With routine maintenance, your Audi will deliver strong performance for years to come. That being said, general wear and tear over time can cause key components to fail and require replacement. The ignition coil is a critical part of your Audi vehicle’s ignition system, but general wear and tear over time, or issues such as moisture damage from fluid leaks or worn-out spark plugs, can cause the ignition coil to malfunction or fail. Common symptoms of a failing Audi ignition coil include:
Difficulty starting the vehicle
Engine misfires or stalls out
The check engine light is on
Rough idling
Loss of power
Backfiring
Reduced fuel economy
If your Audi is experiencing any of these symptoms on the roads in and around Hayward or Milpitas, you should schedule service at Audi Fremont as soon as possible. The certified technicians in our state-of-the-art service center can quickly identify the problem and take the steps necessary to get you safely back on the road.
What is an Ignition Coil?
As noted above, the ignition coil in your Audi is an important part of its ignition system. What does an ignition coil do? The primary function of an ignition coil is to transform the low voltage delivered from the battery into the high voltage that the spark plugs need to ignite the compressed air-fuel mixture in the combustion chambers. To state it simply, if the ignition coil fails, the vehicle won’t run.
In older engines, the high voltage generated by the ignition coil is delivered to the cylinders via a distributor. Most newer vehicles, however, use a coil-on-plug system (COS), which features a dedicated ignition coil for each cylinder.
How to Test an Ignition Coil
An ignition coil can be tested with a multimeter, which is available at most auto parts stores in the Union City area. With a multimeter, you can measure the primary and secondary winding resistance, which should fall within a specific range that will differ depending on the vehicle. You can consult your owner’s manual for information on the resistance values for your specific vehicle’s ignition coil. Note that the high voltage generated by an ignition coil is extremely dangerous and can be life-threatening. It is absolutely essential that the ignition coil is disconnected completely from the wiring before attempting to test it with a multimeter.
Testing a faulty ignition coil can be a little tricky, as it may still function intermittently. In many cases, additional testing will be required. The professionals in the Audi Fremont service center employ the most advanced diagnostic tools available to pinpoint exactly where the problem lies and make the repairs needed to get you back on Newark and San Lorenzo-area roads.
