Peugeot 2008 NOx Catalyst Aging and Exhaust Leak

I'm having an issue with my 2016 Peugeot 2008 gasoline model. The check engine light is on, and the error memory shows a problem with the NOx storage catalyst aging. I also noticed exhaust leaking. The car has 152285 km on it. Any insights?

Summary of the thread

A 2016 Peugeot 2008 gasoline model exhibited a check engine light with an error indicating NOx storage catalyst aging, alongside an exhaust leak. The exhaust leak was identified as the primary cause of the NOx catalyst inefficiency. Repairing the leak resolved the issue, clearing the error code.

Sounds familiar! My old Opel Astra had similar symptoms. NOx issues can be tricky. If your exhaust is actually leaking, that's like trying to bake a cake with a hole in the oven—the system just can't regulate properly. Have you checked for obvious leaks in the exhaust system yourself?

Thank you for your quick response. About checking for leaks, could you elaborate on what I should be specifically looking for?

Sure thing. Think of it like this: your exhaust system is like a long pipe made of several sections. Check where these sections join together - that's where you are most likely to find the leak. You can usually see some soot around a crack. However, since you have experience, I suggest taking it to a workshop. A leak there is often a sign of something else amiss, and the NOx catalyst itself could be failing. It's worth getting a professional diagnosis.

I appreciate the advice. You were spot on! After inspecting the exhaust system, the mechanic found a leak, which was the primary cause of the NOx catalyst inefficiency and the error code. After repairing the leak for 265€, the error was fixed. Thank you!
