O2 Oxygen Sensor Upstream Downstream for Volkswagen CC (2010-2014) 2.0L Turbo

Direct-Fit Upstream & Downstream Oxygen Sensor Kit for 2010-2014 Volkswagen CC (357/358)

What it Does: This matched oxygen sensor kit monitors pre- and post-catalyst exhaust oxygen on the 2010-2014 Volkswagen CC (357/358) with the CCTA 2.0L TSI engine to regulate closed-loop fueling.

The Stock Volkswagen CC Sensor Failure

On the 357/358 CC equipped with the CCTA 2.0L TSI engine, factory oxygen sensors endure extreme exhaust heat and rapid thermal cycling. Over time, PCV blow-by oil vapor and carbon soot contaminate the porous platinum electrodes. Exhaust condensation also causes thermal shock micro-cracking in the zirconia ceramic element, while internal heater circuit burnout triggers P0133, P0135, and P0141 fault codes.

Common Symptoms of a Failing OEM Oxygen Sensor

• Check Engine Light & Heater DTCs: Open heater circuits or slow switching trigger P0135, P0141, or P0133.
• Skewed Closed-Loop Fuel Trim: Fouled upstream elements cause rough idle, hesitation, and P0171/P0172 codes.
• Failed Emissions Readiness: Sluggish downstream voltage tracking fails inspections and triggers P0420.

The Direct-Fit Zirconia Sensor Solution

This matched sensor kit restores factory-grade lambda feedback using laser-welded stainless steel housings and fast-acting zirconia ceramic sensing elements. Each unit matches OE resistance and heater draw specifications for 234-4829 and 234-5019, maintaining stable ECU signal voltage under boost. Factory-keyed connectors and OEM thread geometry allow direct bolt-in installation in stock exhaust bungs with zero cutting or splicing.

Frequently Asked Questions & Fitment Warnings

Does this fit the 357/358 CC?

Yes. This is a direct fit for the 2010-2014 Volkswagen CC equipped with the CCTA 2.0L TSI engine. Does NOT fit 3-sensor CBFA / SULEV models, 3.6L VR6 models, or 2009 and 2015-2017 years.

Will this clear P0135, P0141, and P0133 codes?

Yes. Replacing both sensors as a matched set restores heater circuit continuity and rapid voltage switching to clear P0135, P0141, and sensor-induced P0133 or P0420 faults.

Are factory connectors included for direct installation?

Yes. Both sensors feature plug-and-play OEM connectors; confirm your CCTA engine code before ordering and torque cleanly into the factory bungs.
