At DDP AutoParts, we supply a high-quality NOx (nitrogen-oxide) sensor with OEM reference 80A907807R — a commonly used unit in many Volkswagen Group diesel vehicles. This sensor plays a critical role in the SCR / AdBlue emissions-control system, continuously measuring NOx levels in the exhaust and communicating that data to the ECU for precise urea dosing. A failed or degraded NOx sensor can trigger emission faults, reduce AdBlue efficiency, and cause performance issues. Our replacement option offers reliable accuracy, long-term durability, and a cost-effective alternative to expensive genuine parts.

❓ Frequently Asked Questions 

1. Which vehicles use the NOx sensor part 80A907807R?
   This part is a commonly used NOx sensor (urea injection type) in a range of VAG / Audi diesel vehicles. According to Autodoc, 80A907807R is listed under Audi / VW part equivalents.

   To ensure fitment, provide your VIN and we’ll check the correct sensor for your exact model.

2. Is this a genuine OEM part or an aftermarket equivalent?
   This is an aftermarket replacement built to OEM-equivalent spec. Options include Bosch, Metzger, Ampro, and Vemo.

   While not Audi-branded, it maintains the required functionality and reliability.

3. What are the signs of a failing NOx sensor (80A907807R)?

   • Emissions warning / SCR system fault on the dash.

   • Fault codes related to NOx circuit or AdBlue dosing.

   • Higher than normal AdBlue consumption.

   • Reduced engine performance / derating due to incorrect NOx readings.

4. Where is the sensor located, and how hard is replacement?

   • It’s typically mounted on or near the exhaust system in the SCR setup.

   • You’ll need to safely gain access under the vehicle, unplug the old sensor, unscrew it, and install the new one.

   • After replacement, clearing the fault codes with a diagnostic tool is recommended to allow the ECU to recalibrate.

5. What can cause this NOx sensor to fail?

   • Soot or particulates contaminating the sensor tip.

   • Heat stress, vibration or mechanical fatigue over time.

   • Corrosion or water ingress damaging internal components.

   • Poor-quality AdBlue or incorrect dosing damaging the sensor element.

6. Will replacing the NOx sensor fix all NOx-related warning lights?
   Often yes — if the sensor was the root cause, a new sensor can clear SCR / AdBlue faults. But if there’s deeper damage (e.g. in the catalyst or SCR module), further diagnostics may be needed.

7. Do you offer a warranty or return policy for this sensor?
   Yes — the NOx sensor is covered by our standard parts warranty. If there’s an issue (fitment, performance, or failure), our support team will help you with returns or a replacement.
