Based on industry averages you can expect to pay between $17.49 and $488.00 for a Audi S4 ignition coil.

The Audi S4 ignition coil is a component responsible for converting the low voltage from the battery into the high voltage necessary to create a spark at the spark plugs. It is an essential part of the ignition system, ensuring proper combustion and efficient engine performance. The ignition coil works by generating a magnetic field that, when disrupted, produces a high-voltage spark that ignites the air-fuel mixture in the combustion chamber. This process occurs for each cylinder of the engine, resulting in the smooth and reliable operation of the vehicle.

Signs of Faulty or Worn Audi S4 Ignition Coil

There are a few common signs that indicate a faulty or worn out ignition coil in an Audi S4:

  1. Engine misfires: One of the most noticeable signs is an engine misfire, where you may experience rough idling, stuttering, or a loss of power while accelerating.
  2. Difficulty starting the engine: A faulty ignition coil can lead to difficulty in starting the engine, especially when the vehicle is cold.
  3. Decreased fuel efficiency: Worn out coils can cause a decrease in fuel efficiency due to incomplete combustion, leading to reduced mileage.
  4. Increased emissions: Faulty ignition coils can contribute to increased emissions, resulting in a failed emission test and potentially causing the check engine light to turn on.
  5. Rough engine performance: A worn out ignition coil can result in a vibrating or shaking engine, especially at idle.
  6. Stalling or sudden engine shutdown: In some cases, a faulty ignition coil can cause stalling or sudden engine shutdowns, making it unsafe to drive.
  7. Illuminated check engine light: When an ignition coil malfunctions, it usually triggers the vehicle's onboard diagnostics system, resulting in the check engine light turning on.

If you suspect a faulty or worn out ignition coil in your Audi S4, it is advisable to have it diagnosed and replaced by a qualified mechanic to prevent further damage to the engine.

Replacing Audi S4 Ignition Coils

Certainly! Here are the steps to replace an ignition coil on an Audi S4:

  1. Ensure safety: Park the vehicle on a level surface and engage the parking brake. Also, disconnect the negative terminal of the battery to prevent any accidental electrical shocks.
  2. Access the ignition coils: Open the hood and locate the ignition coil pack. On the Audi S4, they are usually mounted on the top of the engine, directly above the spark plugs.
  3. Remove the engine cover: If your Audi S4 has an engine cover, you may need to remove it to access the ignition coils. The cover is usually attached with a few screws or clips. Unscrew or unclip them, then carefully lift off the cover.
  4. Disconnect electrical connectors: Each ignition coil has an electrical connector attached. Carefully unplug the electrical connectors from each coil. Usually, there is a small tab or clip that needs to be pressed or lifted to release the connector.
  5. Remove the ignition coil: Most ignition coils are secured by one or two bolts. Use a socket wrench to remove the bolts and gently pull the coil out of its housing. Avoid pulling on the coil itself, as it could damage the wiring.
  6. Install the new ignition coil: Take the new ignition coil and align it with the mounting holes. Insert the coil into its housing, ensuring it sits firmly. Replace and tighten the mounting bolts using a socket wrench.
  7. Reconnect electrical connectors: Attach the electrical connectors back onto the new ignition coil. Ensure a secure connection by pressing them in until they click into place.
  8. Repeat for other ignition coils: If you are replacing multiple ignition coils, repeat steps 5-7 for each coil in the same manner.
  9. Reinstall the engine cover: If you removed the engine cover, carefully put it back in place. Align the cover properly and secure it by tightening any screws or clipping it back on.
  10. Reconnect the battery: Finally, reattach the negative terminal of the battery and ensure it is securely tightened.

After completing these steps, you should have successfully replaced the ignition coil(s) on your Audi S4. It is always recommended to consult your vehicle's specific manual or seek professional assistance if you are unsure or uncomfortable performing this task.
