Honda Greiz knocking combustion

I'm having knocking issues with my 2018 Honda Greiz gasoline engine, 173893 km on the odometer. Symptoms include reduced power, jerking during acceleration, and smoke. I suspect combustion chamber deposits or a faulty knock sensor. Has anyone else experienced this?

I had a similar issue with my old Opel Astra diesel: loss of power, jerking, even some smoke. Did you check the simple things first? Are you using good quality fuel? Have you tried fuel additives to clean the fuel system?

I use premium fuel. I'm hesitant to use additives without knowing the cause. Which fuel additives did you use in your Astra, and did you see improvements?

I tried a couple of different fuel additives, but they didn't make a huge difference. The problem kept coming back. Eventually, a workshop confirmed it was carbon buildup. Get it checked by someone who knows what they're doing.

Following your recommendation, a mechanic confirmed substantial deposits in the combustion chamber. The repair, including cleaning, cost 425€. Thanks for your help.
