Oxygen Sensor Concerns in Tarraco Diesel
Summary of the thread
The conversation revolves around a suspected oxygen sensor issue in a 2020 Seat Tarraco diesel, indicated by an illuminated check engine light and increased fuel consumption. The error memory suggests an oxygen sensor heater failure, which could be due to a defective cable or plug connection. A similar issue in another vehicle was resolved by addressing a poor connection and replacing the faulty sensor, suggesting that professional inspection and repair might be necessary.

So, if I understand correctly, the oxygen sensor was the source of the problem and the light only turned on because of a loose connection? Did you fix it yourself or did you take it to the workshop?

Yes, the oxygen sensor's heater element was the core issue, but the light triggered, in my case, due to a poor connection. Though checking the connection is simple, replacing the sensor requires specific tools. I ended up going to a workshop. The eventual repair cost was 95€.

Right, that confirms my suspicions. I will take it to the shop as you did. Thanks for sharing your experience.

I have a Seat Ateca, same engine type, and had a similar issue a while back. The malfunction indicator was constantly on, and the vehicle emissions seemed off. Turned out to be a faulty oxygen sensor, specifically the heater element within it. Have you checked the cable connections and the plug? That's what caused my problem originally.
