Audi Q2 GA Lambda Oxygen Exhaust Sensor Probe Cable 05E906262H

Audi Q2 GA Lambda Oxygen Exhaust Sensor Probe Cable is a component from the Lambda sensors and O2 sensors group, designed for exhaust systems in diesel engines. It is responsible for the precise measurement of exhaust gas composition and nitrogen oxide content, which has a direct impact on the engine control unit's operation, the engine's performance, and emission levels.

Purpose and function in the exhaust system

The presented NOX sensor with cable and lambda probe is dedicated to Audi vehicles from the Q2 GA family powered by Diesel fuel. This assembly integrates the function of a classic oxygen sensor with nitrogen oxide measurement, allowing the engine control unit to continuously adjust the fuel dose, injection system operation, and exhaust gas treatment strategy.

In practice, a properly functioning NOX sensor and lambda probe translate into:

• stable engine operation across the full load range,
• compliance with exhaust emission standards,
• reduced risk of clogging exhaust system components,
• more predictable throttle response.

Benefits of using an original Audi component

The component comes from the Audi line, which means maintaining factory measurement parameters and full integration with the engine control unit software. Compared to replacements, the original NOX sensor with lambda probe ensures:

• consistency of measurement characteristics with injection maps stored in the ECU,
• lower risk of diagnostic errors and limp mode,
• proper cooperation with the exhaust gas treatment system in a diesel engine.

As a result, this is a solution particularly recommended for repairs where maintaining the factory logic of the powertrain is essential.

Performance characteristics and installation

The NOX sensor set with cable and lambda probe is structurally prepared for installation in factory mounting points in the Audi Q2 GA. The use of appropriate connectors and cable length facilitates installation in the existing exhaust system without the need for modifications.

A properly selected element from this group allows you to:

• restore correct exhaust parameter readings after the failure of an old sensor,
• reduce the frequency of emission-related warning lights,
• maintain an optimal regeneration strategy and operation of the exhaust gas treatment system.

The product is offered in Used condition, meaning it comes from disassembly and is intended for users looking for an economical, yet original-compliant service solution.

Application in Audi Q2 GA diesel engines

In Audi Q2 GA diesel units, the role of the NOX sensor and lambda probe is particularly important, as their correct operation determines not only emissions but also the durability of components cooperating with the exhaust system. Accurate data from the sensor allows the engine control unit to precisely control the combustion process, which helps maintain stable performance and predictable fuel consumption.

Replacing a worn or damaged element with a functional component from the same group allows you to restore:

• proper cooperation with the on-board diagnostic system,
• stable fuel dose correction values,
• consistency of engine operation with the manufacturer's factory settings.
