“Kangaroo gasoline” i30 + stabbing stench

Hello! I had a very unpleasant experience today with my i30cw, 1,4l, Bj 2010: Before refueling he ran quite normally. After refueling (Shell FuelSave 95 octan – as always) he then started to take the gas no longer properly. I had to push the gas pedal properly to get from the place. My car had this already 2 times, however, independent of refueling. Now just before the entrance to the house a strong stinging stench was added, like burned rubber. I am around the The car was running around, but couldn’t find anything. Tomorrow I’ll drive to the workshop. Also my consumption continues to rise continuously, now it’s 11,5l/100km. Has anyone ever experienced such a thing with your car? Greetings
