Hyundai i10 engine stalling at idle

My 2019 Hyundai i10, gasoline engine, with 141040 km, has an issue. The check engine light comes on and the engine stalls at idle. Error memory shows a problem with incorrect fuel composition. I suspect a defective cable or plug connection.

Summary of the thread

A 2019 Hyundai i10 with a gasoline engine is experiencing stalling at idle and a check engine light, with an error indicating incorrect fuel composition. The suspected cause is a defective cable or plug connection, possibly related to the fuel composition sensor. A suggested solution is to inspect the sensor connection and consult a workshop for further diagnosis and repair, which previously cost another owner around 95€.

Whoa, that sounds familiar! I have an i10 too. I had almost the exact same symptoms a while back - check engine light, rough idle, the whole shebang. It was driving me nuts! Did you recently fill up at a different gas station than usual? Or maybe used a fuel additive? Incorrect fuel composition could point to a bad batch of fuel.

Interesting. No change in gas station or additives. Which component's cable/plug connection are you referring to?

I'm no mechanic, but I remember reading something about the fuel composition sensor having a fragile connector. But honestly, chasing it yourself might be a pain. I'd recommend a workshop. My issue was similar, but a bit more complex, and they eventually traced it to a faulty sensor connection. Cost me around 95€ to fix.

Thanks for the info. I'll check the sensor connection and then take it to a shop. The diagnostic and repair indeed pinpointed a defective plug connection, costing 95€. Appreciate the help!
