TRQ Upstream O2 Oxygen Sensor Fits 2013-2019 Audi 2014-2018 Volkswagen

In this review the TRQ Upstream O2 Oxygen Sensor is evaluated for drivers who need a direct-fit, aftermarket replacement for specific Audi and Volkswagen engines. The bottom line: it is best for DIY mechanics and independent shops that want a low-cost, vehicle-specific oxygen sensor that installs without modification. The reviewer found the sensor easy to install and a clear value buy when it functions correctly, but some buyers reported mixed reliability and fitment issues so buyers should check the listing fitment closely before ordering.

Key Features

• Direct Fit: The sensor is designed to replace the factory unit without modification, saving time during installation and reducing the chance of wiring changes.
• OE Replacement: Built as an OE replacement option so it should meet basic performance expectations for emissions feedback on compatible engines.
• Vehicle Specific Fitment: The listing includes detailed compatibility notes for Audi and Volkswagen models so buyers can confirm match to their engine and bank before purchase.
• Aftermarket Reference Numbers: Multiple reference numbers such as 0258027052 and LS27052 are provided to help owners cross-check compatibility with existing parts.
• Upstream Position: Supplied for upstream Bank 1 Sensor 1 locations on the listed models, which is the critical position for air-fuel mixture reporting.

Who It's For

The TRQ upstream oxygen sensor is a practical choice for vehicle owners and independent mechanics who need an affordable, straightforward replacement for compatible 2013-2019 Audi and 2014-2018 Volkswagen models. It suits those comfortable verifying fitment against the listing and performing a standard sensor swap.

Those who should look elsewhere include drivers who require a factory-warranty part or who cannot tolerate any risk of early failure; there are reports of mixed long-term reliability and occasional defective units, so OEM purchases or a part with an extended warranty may be preferable for higher-risk use.
