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) dosing and reduce emissions.

Q2: Where is this sensor installed?
A2: It is installed in the exhaust aftertreatment system, typically before or after the SCR catalyst depending on engine layout.

Q3: Are these part numbers interchangeable?
A3: These are closely related OEM and Continental cross-reference numbers, but exact matching is required because calibration and wiring variants may differ.

Q4: Is this used only on T5?
A4: It is mainly used on VW T5/T6 commercial diesel SCR systems, but some part numbers also appear across VW Group MQB/MLB platforms.

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