FAQs

What is the primary function of a NOx sensor in an AdBlue system?

The NOx sensor measures the level of nitrogen oxides in the exhaust gas. This data is used by the vehicle's computer to control the amount of AdBlue injected into the exhaust system to convert NOx into harmless nitrogen and water.

How do I know if my Hella NOx sensor needs replacement?

Symptoms often include dashboard warning lights (Check Engine, AdBlue warning), reduced engine power, increased fuel consumption, or failure to pass an emissions test. Diagnostic trouble codes (DTCs) specific to NOx sensors are the most reliable indicator.

Can I install the Hella NOx sensor myself?

While possible for experienced DIY mechanics, NOx sensor replacement usually requires specialized tools and diagnostic software for proper installation and calibration. Professional installation by a qualified technician is recommended.

What vehicles is the Hella 6PN 358 307-191 compatible with?

This sensor is designed for specific Mercedes-Benz models: E-Class (W212) 2009-2016, E-Class T-Model (S212) 2009-2018, and M-Class (W164) 2009-2011. Always verify fitment with your vehicle's specifications.

Does this sensor require any programming or calibration after installation?

Yes, typically NOx sensors require adaptation or calibration using a diagnostic tool after installation to ensure accurate readings and proper system function.

What is OE-quality?

OE-quality means the part is manufactured to the same standards and specifications as the original part supplied by the vehicle manufacturer (Original Equipment).

Troubleshooting

Check Engine Light or AdBlue Warning Light Illuminated

This could indicate a faulty NOx sensor, an issue with the AdBlue system, or an exhaust leak. Have the vehicle's diagnostic codes read by a professional to pinpoint the exact cause.

Reduced Engine Performance or Increased Fuel Consumption

A malfunctioning NOx sensor can lead to incorrect AdBlue dosing, impacting engine performance and efficiency. Ensure the sensor is correctly fitted and calibrated, or consider replacement if diagnostics indicate failure.

Emissions Test Failure

A faulty NOx sensor will directly affect the vehicle's ability to meet emissions standards. Replacement of the sensor, if diagnosed as the fault, is necessary.
