Fitment

Based on OE catalog cross-reference data, 059907807T / A2C10327000-085C is used in Volkswagen Group V6 TDI diesel SCR (AdBlue) systems.

Common applications include:

• Audi Q7 (4L / 4M early diesel configurations depending on engine code)
• Volkswagen Touareg (7L / 7P V6 TDI diesel)
• SCR (AdBlue) diesel emission systems (Euro 5 / early Euro 6 platforms)

Fitment is strictly based on OE number matching: 059907807T / A2C10327000-085C

OE listing data confirms this NOx sensor is part of the Continental/Vitesco-controlled SCR system used on VAG V6 TDI platforms.

Technical Description

This NOx sensor measures nitrogen oxide (NOx) concentration in diesel exhaust gases and transmits real-time data to the ECU.

It is part of the SCR (Selective Catalytic Reduction) system and controls AdBlue dosing strategy to reduce emissions and maintain compliance standards.

The sensor is an integrated electronic module designed for high-temperature exhaust environments and continuous emissions monitoring.

Symptoms / Fault Codes

Common symptoms of failure may include:

• Check engine light
• SCR / AdBlue system warning
• P2200 / P229F fault codes (system dependent)
• Reduced engine performance (limp mode)
• Increased emissions

FAQ

Which vehicles use this NOx sensor?

It is commonly used on Volkswagen Touareg and Audi Q7 diesel models equipped with V6 TDI engines and SCR (AdBlue) systems.

Is this sensor interchangeable with similar OE numbers?

Not recommended. Even small suffix differences (T / R / G / B variants) can indicate different ECU calibration or sensor position (upstream/downstream).

Why do Porsche / Audi / Volkswagen appear together?

Because this is a Volkswagen Group shared diesel SCR component used across multiple brands on the same emission architecture.

Is this a diesel or gasoline sensor?

This is a diesel NOx sensor used in SCR (AdBlue) systems only.
