Fitment

Based on OE catalog data, 06F907807H is an earlier-generation Volkswagen Group emissions-related sensor used across selected VAG petrol engine platforms with emissions monitoring functions.

Common applications include:

• Volkswagen Passat B6 / B7 (select petrol engine variants)
• Volkswagen Golf Mk5 / Mk6 (selected FSI / TSI configurations)
• Audi A3 (8P) petrol engine variants
• VAG EA113 / early EA888 platform emissions systems

Fitment is strictly based on OE number matching: 06F907807H

Technical Description

This sensor is used within the engine emissions control system to monitor exhaust-related parameters for ECU feedback.

It supports engine management functions related to fuel mixture control and emissions regulation in petrol engine applications.

Unlike later SCR NOx sensors used on diesel systems, this is part of an earlier-generation emissions monitoring architecture.

Symptoms / Fault Codes

Common symptoms of failure may include:

• Check engine light
• Reduced engine performance
• Emissions-related fault codes (varies by ECU system)
• Rough idle or fuel mixture irregularities

FAQ

What does this sensor do?

It monitors exhaust/emissions-related parameters and sends signals to the ECU for engine management and emissions control.

Is this a NOx sensor for diesel SCR systems?

No. This is an earlier-generation emissions sensor used mainly in petrol engine platforms, not SCR AdBlue systems.

Is this vehicle-specific?

Yes. It is strictly matched by OE number and used only in specific Volkswagen Group petrol engine applications.

Can similar sensors be used instead?

Not recommended. ECU-calibrated sensors must match exact OE specification for correct engine operation.
