Renault Wind Engine Light and Exhaust Smell

My 2010 Renault Wind (gasoline engine) has the check engine light on, rough running, and a strong exhaust smell at 112138 kilometers. Could this be a failing catalytic converter or particulate filter? I know DEF fluid is for diesels.

I had similar symptoms with my 2012 Opel Corsa: engine light, rough running, and a strong exhaust smell. It turned out to be a faulty lambda sensor.

Could you elaborate on the specific symptoms you experienced with your Opel Corsa, and how the defective lambda sensor was diagnosed?

The symptoms were exactly as you described: engine light on, rough idle, and a distinct exhaust odor. A workshop confirmed the diagnosis using an OBD reader. I advise consulting a professional workshop.

The diagnosis pointed towards a defective lambda sensor, as you suggested. The repair cost 375€ and has resolved the issue entirely. I can now drive again with pleasure.
