The exhaust leak appears to originate near the NOx sensor. Could you elaborate on the specifics of the nitrogen oxide sensor failure you experienced?

In my case, the sensor was faulty, leading to incorrect readings and triggering the check engine light. Given the proximity of your exhaust leak to the sensor, it is advisable to consult a workshop. The repair will probably be around 95€

Thank you for the clarification. I will have the vehicle inspected at a workshop as suggested. The NOx sensor and its connections will be carefully examined.

I had similar symptoms in my Avancier, though I haven't checked the build year. A faulty nitrogen oxide sensor can trigger those issues. Is the exhaust leak near the sensor itself? A damaged catalytic converter could cause similar problems.
