Citroen C3 Failing MOT on Emissions - Need Advice!

Unsteady engine

I own a 2013 Citroen C3 with 194,000 km on the clock, and I'm facing a recurring issue where my car fails the MOT every year due to emissions. Each garage I visit suggests replacing the catalytic converter, but I'm not convinced that's the root cause. I mostly drive short distances, like going to the shop and back. The engine feels unsteady, but there's no engine management light on. What should I be looking into to resolve this issue? Any advice or similar experiences would be greatly appreciated!

Consider taking your car for a longer drive on the highway to allow the engine to reach optimal operating temperature and help clear out any carbon build-up, which can improve emissions. This is sometimes referred to as an "Italian tune-up." After doing this, see if there's any improvement in the engine's performance and emissions. Let me know how it goes or if you have any further questions!
