Key Technical Specifications

• Model: V10-76-0050
• Type: Lambda (Oxygen) Sensor
• Thread Size: M18 x 1.5 mm with pre‑grilled D‑shaped thread
• Polarity: 4‑pole configuration for robust signal integrity
• Operating Temperature Range: -40 °C to +120 °C (typical automotive range)
• Voltage Supply: 12–14 V DC (standard ECU supply)
• Signal Output: Analog voltage proportional to oxygen concentration
• Response Time: < 200 ms for rapid mixture adjustments
• Material: High‑temperature ceramic core with stainless steel housing

Vehicle Compatibility

The sensor is engineered to fit a wide array of vehicles across multiple manufacturers. Notable compatibility includes:

• Volkswagen Group: A4, A5, A6, A7, A8, Q5, Cordoba, Ibiza, Fabia, Roomster, Passat, Polo
• Audi models with VAG engine families
• Skoda and Seat vehicles sharing the same engine architecture
• Other OEMs that use the M18x1.5 thread standard for lambda sensors

Installation Guide

1. Preparation: Disconnect the vehicle battery to prevent electrical hazards.
2. Accessing the Sensor: Locate the exhaust manifold or catalytic converter where the existing lambda sensor is mounted. Remove any protective covers if present.
3. Removing Old Sensor: Use an appropriate socket or wrench to unscrew the old sensor, taking care not to damage the thread.
4. Installing V10-76-0050: Align the D‑shaped pre‑grilled thread with the exhaust fitting. Tighten securely but avoid over‑torqueing to prevent cracking of the ceramic core.
5. Reconnecting Wiring: Attach the sensor’s connector to the ECU harness, ensuring a firm connection and correct polarity.
6. Testing: Reconnect the battery, start the engine, and allow it to reach operating temperature. Verify that the ECU registers the sensor signal and that the vehicle runs smoothly without misfires or warning lights.

Performance Benefits

The Vemo V10-76-0050 delivers:
