Walker 250-24417 Oxygen Sensor

Walker OE Oxygen Sensor for Select Volkswagen and Audi

Walker Products OE oxygen sensor 250-24417 is a heated, specific-fit replacement built for vehicles that rely on accurate exhaust feedback to the ECU. It is designed for upstream and downstream applications across select Volkswagen and Audi models, including Pointer, Pointer Truck, A4, A4 Quattro, Passat, EuroVan, and Cabriolet.

With a 4-wire design, 18.0 mm thread diameter, threaded mounting, and a radiused polygon male connector, this sensor is built to match the original application and connector style. The 54.25 in. wiring harness and 57.8 in. overall length support proper routing on the intended vehicle positions.

Product Details

Walker Products OE focuses on original-equipment-style engine management and oxygen/air-fuel sensors for a wide range of vehicles worldwide. Part number 250-24417 is engineered for the specified fitment position so the ECU receives the correct diagnostic feedback. This matters on vehicles such as the Volkswagen Pointer and Audi A4, where an oxygen sensor fault can trigger poor running, higher fuel use, increased emissions, or a malfunction indicator light.

This part cross-references Walker Products OE applications for the same vehicle fitment. For buyers searching for a Volkswagen Pointer upstream oxygen sensor, Audi A4 Quattro upstream oxygen sensor, or Volkswagen EuroVan downstream oxygen sensor, 250-24417 is listed for those exact positions in the fitment data.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rough engine operation caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel readings
• Elevated exhaust emissions from a failing sensor
• Fault codes stored in the ECU for the affected sensor circuit

Installation Notes

• Confirm the exact year, make, model, and sensor position before ordering.
• Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation.
• Verify the threaded mounting location and connector orientation match the original sensor.
• Use the fitment listing to match upstream, downstream, downstream right, or downstream left applications exactly.
