This sensor provides detailed lambda-range feedback for modern engine management, helping the ECU maintain accurate mixture control for fuel efficiency, performance, and lower emissions. The wideband design, optimized heater control, and fast light-off characteristics support reliable response during rapid throttle changes and thermal cycling. This Bosch oxygen sensor is used in applications such as Volkswagen CC, Volkswagen GTI, and Audi A3 fitments, with specific upstream and downstream coverage depending on the vehicle.\u003c\/p\u003e\u003cp\u003eThis part cross-references Bosch 17197 for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Is Used For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIncorrect air-fuel ratio readings from a worn sensor\u003c\/li\u003e\n\u003cli\u003eCheck engine light concerns related to oxygen sensor performance\u003c\/li\u003e\n\u003cli\u003eReduced fuel economy caused by inaccurate mixture feedback\u003c\/li\u003e\n\u003cli\u003eRough engine operation tied to poor sensor response\u003c\/li\u003e\n\u003cli\u003eEmissions issues from degraded wideband sensor output\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eFits 2009-2017 Volkswagen CC, upstream; 2014-2016 Kia Forte, downstream; 2014-2016 Kia Forte Koup, downstream; 2014-2016 Kia Forte5, downstream; 2012-2016 Kia Soul, upstream; 2007-2016 Volkswagen Eos, upstream; 2009-2015 Audi TT Quattro, upstream; 2009-2015 Audi TTS Quattro, upstream; 2011-2014 Hyundai Elantra, upstream; 2013-2014 Hyundai Elantra Coupe, upstream; 2013-2014 Hyundai Elantra GT, upstream; 2006-2014 Volkswagen GTI, upstream; 2006-2013 Audi A3, upstream; 2009-2013 Audi A3 Quattro, upstream; 2012-2013 Volkswagen Golf R, upstream; 2006-2010 Volkswagen Jetta, upstream; 2006-2010 Volkswagen Passat, upstream; 2009-2010 Volkswagen Passat CC, upstream; 2008-2009 Audi TT, upstream.
