When there are symptoms of rough idle, weak acceleration, increased fuel consumption, or the check engine light (especially codes related to the emissions system), this typically means the NOx sensor has aged or failed and cannot accurately monitor nitrogen oxides. The sensor normally provides real-time feedback to the ECU on exhaust composition to help precisely control fuel injection and SCR injection to ensure efficient combustion and meet emission standards. This VW NOx sensor OEM number 059907805B fits VW Touareg, Audi Q7, Porsche Cayenne and other models with 3.0TDI diesel engines. Installation must be performed cold; disconnect the battery negative before removal, and watch sensor wiring path to avoid interference with exhaust or underside components. After installation, use a diagnostic tool to clear fault codes and relearn.
