    My 2021 Kia Seltos two-litre pings when pushed. It does it in all drive modes...
    Answered by David Morley · 14 July 2022

    I would reject the assertion that all modern engines ping because they run lean. Pinging (or detonation or pre-ignition, call it what you will) is a symptom of a problem (usually with the ignition timing or fuel mixture) and it’s not something you should expect to hear. Over time, continued pinging will damage the engine’s internal components and then you’re faced with a huge bill instead.

    The knock sensor should detect the first signs of pinging (even before you’ve heard it) and adjust the engine’s ignition curve (generally) to stop it happening. So, either the knock sensor’s not working or the computer that is supposed to control the engine’s settings isn’t operating correctly. The fact that a tankful of 98RON fuel stops the problem suggests that the engine settings are off.

    Kia recommends normal 91 RON ULP for the Seltos and says that E10 fuel is also compatible with the vehicle. So there should be no need to buy the more costly 98 RON stuff just to prevent the engine pinging. Your vehicle is still well and truly under warranty, so make it Kia’s problem to fix it. And don’t be fobbed off by `they all do that, Sir’.
