Peugeot 206 Knocking Combustion
Summary of the thread
A 2014 Peugeot 206 with a gasoline engine started experiencing knocking, reduced power, jerking during acceleration, and smoke from the exhaust, accompanied by an error code. The suspected cause was combustion chamber deposits. A suggestion was made to try higher octane fuel to address potential pre-ignition issues. Ultimately, a workshop confirmed the deposits, and after cleaning and tuning, the car's performance improved significantly.

Yes, it pings under load. I've been using standard unleaded. Do you mean premium gasoline? I know about octane ratings, but didn't realize substandard fuel could cause such knocking. Is the smoke related?

Yep, premium gas. See if that helps. The smoke could be related or separate. If it continues after a tank or two, take it to a shop. Could be a bad knock sensor or worse. Don't risk engine damage.

I took it to a workshop. They confirmed combustion chamber deposits. The cleaning and tuning cost 425€. My Peugeot runs smoothly again!

I had something similar with my 206. Is it a pinging sound, especially under load? Reduced power and jerking are classic symptoms. Have you tried higher octane fuel? Cheap fuel can cause pre-ignition.
