Seat Arosa Diesel O2 Sensor Issue

I encountered a similar situation with my Arosa. The check engine light illuminated, and the error memory indicated an issue with the O2 sensor. It sounds like your exhaust system might be the culprit. Have you checked the wiring and connections to the exhaust sensor? Sometimes, a loose or corroded connection can trigger these symptoms. Think of it like a faulty wire in a lamp – it can prevent the light from working even if the bulb is fine.

Thank you for your response. When you mention 'exhaust sensor wiring', could you be more specific? Are there particular points I should inspect?

Yes, the exhaust sensor wiring refers to the electrical connections leading to the O2 sensor. Focus on the plug that connects the sensor to the car's wiring harness. Corrosion or damage there is common. Given the symptoms and potential for misdiagnosis affecting the exhaust system, consider a workshop visit for proper diagnostics. An O2 sensor issue can impact car maintenance significantly.

Confirmed. The Seat workshop identified a defective plug connection on the exhaust sensor. Repair cost was 95€. Thank you for the insight.
