Intermittent check engine light problem on a Peugeot 308

Hello everyone, I own a 2015 Peugeot 308 with 90,000 km on the odometer. I've noticed an unusual exhaust smell inside the vehicle while idling in the garage, sometimes with a slight drop in idle speed. In addition, the engine warning light sometimes comes on, but rarely, and I have to manually clear it. This happens without any loss of power, no lack of oil, with a stable idle and without increased fuel consumption. Has anyone ever encountered this problem or have an idea of the possible cause? Thanks in advance for your advice!

Check for any exhaust leaks, particularly around the exhaust manifold or connections. An exhaust leak can cause fumes to enter the cabin and may trigger the engine warning light. This is a safety concern, so it's important to address it promptly. Let me know if you find anything or have further questions!

Check the throttle body for dirt or carbon buildup, as this can cause stalling issues. Cleaning it might resolve the problem. Let me know if this helps or if you have any further questions!
