Interesting. You mention a similar issue. Could you elaborate on what the car diagnostics specifically reported regarding the NOx catalyst, and what ultimately resolved the problem for you?

The diagnostics pointed towards reduced efficiency of the NOx catalyst, likely due to the leak you mentioned. Yes, it was indeed a leak in the exhaust system. I would recommend getting it checked by a workshop as soon as possible to prevent further damage.

Thank you for confirming. A leak in the exhaust system was detected, leading to the NOx catalyst aging prematurely. The repair cost 265€. I appreciate your insight.

I also drive a Skoda Superb, and I had a similar issue with NOx emissions. The check engine light was on, and the car diagnostics indicated a problem with the NOx catalyst. Was your fuel efficiency also affected? Did you notice any unusual smells?
