Nox Sensor For Vw Transporter California T6 04L907805Bt 04L907805Cd 04L907805Cg

At DDP AutoParts, we offer a dependable NOx (nitrogen-oxide) sensor (OEM reference 04L907805BT / 04L907805CD / 04L907805CG) tailored for the VW Transporter and California T6 2.0 TDI models. This sensor is crucial for your vehicle’s SCR or AdBlue emissions control system, monitoring NOx levels before or after the catalytic converter and feeding accurate data back to the ECU. A failing NOx sensor can cause emission warning lights, increased AdBlue consumption, or even derating — but with our high-quality replacement, you’ll restore proper emissions performance, reduce fault risk, and maintain compliance with lower running costs compared to OEM.

❓ Frequently Asked Questions 

1. Which VW models / years does this part fit?
   The NOx sensor is compatible with VW Transporter (T6) and VW California (T6) 2.0 TDI models. It fits versions using the part numbers 04L907805BT, 04L907805CD, or 04L907805CG.

   If you're unsure, you can provide your VIN, and we’ll double-check compatibility for your specific vehicle.

2. Is this a genuine VW / OEM part or an aftermarket equivalent?
   This is a high-quality aftermarket NOx sensor, made to match OEM performance. While not VW-branded, it uses the correct spec and connector to integrate seamlessly with your emissions system.

3. What problems can occur when the NOx sensor fails?

   • Emissions or AdBlue warning light on the dashboard.

   • Poor AdBlue efficiency / higher AdBlue consumption.

   • Engine derating or reduced performance when the ECU gets incorrect NOx readings.

   • Fault codes related to the NOx circuit, e.g. “sensor heater / circuit error.”

4. How difficult is it to replace this sensor?

   • The sensor is often mounted on or near the vehicle’s exhaust system, so you may need to safely lift the vehicle to access it.

   • You’ll need to disconnect the sensor plug, unscrew the old NOx sensor, and fit the new one with care.

   • After installation, clearing any existing fault codes using a diagnostic tool is recommended so the ECU can re-learn the new sensor.

5. Do I need to calibrate or program anything after fitting the new sensor?
   No special “coding” is normally needed for a NOx sensor replacement, but you should clear stored fault codes with an OBD diagnostic tool to ensure the system calibrates correctly.

6. What causes NOx sensors to go bad?

   • Contamination from soot or unburnt fuel can degrade the sensing element.

   • Water or condensation ingress can damage internal components (documented for similar NOx sensors).

   • Heat and vibration over time, especially in harsh exhaust environments.

   • Poor-quality AdBlue or incorrect dosing might affect the sensor longevity.

7. Will replacing this sensor fix all SCR / AdBlue warning lights?
   It can resolve many NOx-related warning lights or derating issues — especially if the fault was caused by a degraded sensor. However, if there’s a problem upstream (e.g., a blocked SCR catalyst), further diagnostics may be required.

8. Do you offer a warranty or after-sales support?
   Yes — this NOx sensor comes with our standard parts warranty. If there’s a fitment issue or the part fails after installation, our customer service team can help with testing, replacement, or return.

9. Why choose this sensor from DDP AutoParts instead of a VW dealer?

   • Cost efficiency: More affordable than OEM dealer parts.

   • Quality: Aftermarket units are built to suit emissions-critical applications.

   • Availability: We hold stock to reduce waiting times.

   • Support: We provide advice on fitment, fault code reset, and installation.
