No DEF fluid in a 2008 gasoline engine, that's diesel tech. Which sensor was the problem for you exactly? And where was the exhaust leaking?

Right, sorry, forgot the year! For me it was definitely the oxygen sensor, and the exhaust leak was near the particulate filter. Honestly, best to get it checked at a workshop, could be several things.

Confirmed: defective lambda sensor. Replaced it; running smoothly now. Total cost: 375€. Thanks for the pointer!

I had something similar with my i20. Engine light, rough running... was it DEF fluid related for you? Or maybe the oxygen sensor? Have you checked the exhaust pipe for leaks?
