Description

The 04C 905 110L ignition coil generates the high-voltage electrical pulse that each spark plug needs to ignite the air-fuel mixture inside the cylinder. This coil is sold individually and serves as a direct replacement for the original unit on compatible Volkswagen and Audi engines.

Each cylinder uses a dedicated coil. Consequently, a single failing coil can cause a misfire in that cylinder while the rest of the engine continues to run. Replacing the faulty coil restores correct spark delivery and helps the engine run smoothly again.

Why It Matters

Ignition coils operate under high electrical and thermal stress during every drive cycle. Over time, internal insulation can break down. As a result, the coil may produce a weak spark or fail entirely.

A weak or missing spark causes incomplete combustion. Furthermore, unburned fuel can enter the exhaust system and damage the catalytic converter. Addressing a failing coil promptly protects both engine performance and downstream components.

For best results, replace all ignition coils and spark plugs together during the same service. This approach ensures consistent spark delivery across all cylinders.

Signs of Failure

Inspect the ignition system if you notice:

  • A check-engine light with a cylinder-specific misfire code.

  • Rough or uneven idle.

  • Hesitation or stumbling during acceleration.

  • Reduced power output.

  • Decreased fuel economy.

  • Engine shaking at idle or low speed.

  • A strong fuel smell from the exhaust.

Service Notes

Always verify fitment by VIN before ordering. Confirm the number of cylinders in the engine before ordering to determine the total quantity of coils needed. For consistent ignition performance, replace all coils and spark plugs as a complete set during the same service interval.
