Bosch 0258006980 – Lambda Sensor with Vehicle‑Specific Connector

The Bosch 0258006980 is a high‑performance lambda (oxygen) sensor designed for use in the exhaust systems of a wide range of European vehicles. It features a vehicle‑specific connector that ensures a perfect fit and reliable electrical contact, eliminating the need for adapters or additional wiring.

Key Functionalities

The sensor measures the oxygen concentration in the exhaust gases, providing critical data to the engine control unit (ECU). This information is used to adjust the air‑fuel mixture, optimize combustion efficiency, and reduce harmful emissions. The Bosch 0258006980 delivers:

• Accurate O₂ measurement across a wide temperature range.
Fast response time, enabling real‑time adjustments to engine parameters.
• Durable construction that withstands high temperatures and corrosive exhaust gases.
• Integrated vehicle‑specific connector for seamless installation.

Technical Specifications

Vehicle Compatibility Overview

The Bosch 0258006980 is engineered to fit a broad spectrum of vehicles, ensuring that the sensor’s connector matches the factory wiring harness. Below is a concise list of supported models:

• Audi A3 (8L1), Audi TT (8N3/8N9), Audi S3 (8L1)
• Seat Ibiza, Seat Leon, Seat Cordoba
• Skoda Fabia, Skoda Octavia, Skoda Superb
• Volkswagen Golf IV/V, Volkswagen Polo, Volkswagen Passat, Volkswagen Beetle
• All models equipped with a 1.8 L or 2.0 L engine and a catalytic converter between 1999 and 2006.

Installation Guide

Replacing the lambda sensor is straightforward, thanks to the vehicle‑specific connector that eliminates the need for additional adapters:

1. Locate the sensor: It is typically positioned on the right side of the exhaust manifold, either before or after the catalytic converter.
2. Disconnect the battery to prevent accidental ECU activation.
3. Remove the old sensor by loosening the mounting clamp and gently twisting the connector out of the harness.
4. Insert the Bosch 0258006980: Align the connector with the harness, ensuring a snug fit. Tighten the mounting clamp securely.
5. Reconnect the battery and start the engine to verify proper operation. The ECU should recognize the new sensor without error codes.
