FAQ

Q1: What is the function of this NOx sensor?
A1: It measures nitrogen oxide levels in diesel exhaust and sends data to the SCR system to control AdBlue (DEF) injection and reduce emissions.

Q2: Where is this sensor installed?
A2: It is installed in the exhaust aftertreatment system, typically behind the turbocharger or near the SCR catalyst depending on configuration.

Q3: Are all listed part numbers interchangeable?
A3: They are cross-reference OEM and aftermarket numbers for the same sensor family (Continental/Bosch-based units), but exact matching is still required for correct calibration.

Q4: Is this used only in Amarok?
A4: It is primarily used in Volkswagen Amarok 3.0 TDI (2016–2022), but may also appear in other VW Group SCR diesel platforms.

Q5: What are common failure symptoms?
A5: Engine warning light, AdBlue/SCR system faults, NOx sensor signal errors, or reduced engine performance mode.
