OVERVIEW
Individual ignition coil for the matching engine
Genuine VW/Audi 06H-905-110-L supplies the high-voltage ignition output to the spark plug at its assigned cylinder. The coil-on-plug design connects directly to the plug through the integrated boot.
The low-voltage connector receives the vehicle's electrical supply and control connection. A sound coil, correctly specified spark plug and intact wiring work together to produce reliable ignition under the engine's operating conditions.
Technical details
- Complete factory number: 06H-905-110-L.
- Factory specification: individual coil-on-plug ignition unit, factory number 06H-905-110-L.
- Design: single-cylinder coil assembly with plug boot and matching electrical connector.
- Quantity supplied: one individual ignition coil; spark plug, vehicle wiring and additional coils are separate.
Retain the full L suffix when comparing the original unit. The vehicle may have received a later service revision, so confirm the installed number, connector and application before ordering. This listing supplies one coil rather than a four-cylinder set.
Common reasons to replace
- Diagnosis confirms a failed or intermittent coil at the affected cylinder.
- The coil housing, connector or plug boot is damaged.
- Testing identifies insulation breakdown or loss of ignition output under load.
A cylinder misfire can also result from a worn spark plug, damaged wiring, fuel delivery or a mechanical fault. Inspect the plug well for oil or moisture and follow the factory diagnostic procedure before replacing the coil. Correct the source of contamination when present.

Installation guidance
Follow the factory ignition-system service procedure with the engine switched off and cool. Release the connector lock carefully, use the specified removal method and seat the replacement coil fully on the correctly installed spark plug.
Reconnect and lock the wiring connector, complete the required fault checks and verify that the affected cylinder operates correctly. Address any related plug, wiring or plug-well problem found during diagnosis.
