Pulsar NOx storage catalyst aging

Hey, I had a similar issue with my Pulsar. Check engine light, same error code... NOx emissions were way off. Is the exhaust leak near the catalyst? That could be the culprit. Have you noticed any changes in fuel economy?

Thanks for the quick reply. I haven't really noticed any difference in fuel economy, but the exhaust leak does seem to be coming from somewhere around that area. Is it expensive to repair?

Yeah, that sounds like it. I messed around trying to fix it myself but ended up taking it to a workshop. It's a pain to get to, and you really need to make sure it's sealed properly or the NOx emissions errors will just come back. Save yourself the headache and take it to a professional.

Appreciate the advice. I'll take it to a local workshop. Turns out, a small crack in the exhaust system was causing the leak and messing with the NOx sensor readings. Repair came out to be 265€. Thanks again!
