Greetings to everybody, The check engine light sometimes activates, sometimes being on for days and other times for weeks. The diagnostic tool indicates O2 Sensor 1 Bank 1, suggesting it is located on the DPF just behind the engine. 2.0 CRDi engine. Is there anybody who can verify this? I would be grateful if you could provide me with the OEM code to obtain a replacement. I hope someone here has seen this problem before.
Thank you!

The precise code was not provided, hence it is presumed to pertain to the O2 sensor 1, Bank 1. It is the first one before the converter. The component number is 39210-2G720. These are often not difficult to replace, since they are largely shielded from environmental factors in their location. I would inspect the wire for any mouse damage and the connection before placing an order. OEM units are rather expensive. Best of luck.

I apologise; you are correct. I posted late at night. P2196 O2 Sensor Signal Biased/Stuck Rich Bank 1 Sensor 1

A powerful engine increases the likelihood of damaging or melting the catalytic converter, resulting in significant expenses.

Are the sensors for petrol and diesel identical?

Are there any updates about this matter? I am on vacation and experiencing the same issue. I have a dealer appointment scheduled for tomorrow. I hope they can resolve the issue promptly, since being without a vehicle while vacation would be disappointing.

The same issue, wherever you have tried and shown the same code, or you exhibit analogous symptoms.

Precisely, same code

As you are aware, codes do not inherently equate to "replace sensor."

It indicates that the issue may be related to the High Pressure Oil Pump.
