Volkswagen Polo / Audi Front Oxygen Sensor 03C906262J 1K0998262C

Product overview

This new front oxygen sensor is cross-referenced to OE numbers 03C906262J and 1K0998262C. The listing shows it for Audi and Volkswagen applications, naming the VW Polo 1.6. An oxygen (lambda) sensor reports exhaust oxygen content to the engine computer, which uses it to trim fuelling. A tired sensor can lead to poor fuel economy, rough idle, failed emissions readings and a check engine light.

Vehicle compatibility

The listing names Audi and VW Polo 1.6 models but provides no year range, engine code or fitment table. The listing also marks it as universal fitment; however, oxygen sensors vary in plug type, lead length and mounting position, so they should always be matched by part number. Check the number printed on your current sensor or have your VIN checked by a parts specialist before ordering.

Key features

• Front (upstream) oxygen sensor, as described in the part listing
• OE-reference numbers 03C906262J and 1K0998262C
• Metal and plastic construction
• New replacement for the vehicle's auto electrical system

Technical specifications

Installation requirements

Diagnose the fault with a scan tool first, as fuel-trim and sensor codes can be triggered by vacuum or exhaust leaks. With the engine cold, unplug the sensor, unscrew it with an oxygen sensor socket and fit the replacement, keeping the sensing tip clean. Route the lead away from hot exhaust parts. Professional installation is recommended for engine-management and electrical components.

Fitment checks before ordering

Vehicle data is limited. Confirm the sensor by OE number or VIN before ordering, and compare the plug and lead length with your existing sensor. If the new sensor does not clear the fault, further diagnosis of the wiring and exhaust system is advised.
