Hello,
My i30 1.6L GDI engine has began emitting metal knocking sounds after about 20 minutes of driving from a cold start. The knocks happen only at 1500 to 2000 RPM. The knocks don't happen all the time, but mostly when driving in the city when traffic speed is low.
I have replaced the spark plugs and ignition coils with a brand new ones, cleaned up the throttle body but the knocking still persists. Will be happy to know if you experienced such issues with the 1.6L GDI engine or have a suggestion how to fix the issue.
thanks,
Yaniv
