Can you tell me when the knocking issue started? From what I've read, it seems like around 1500-2000 kms.
Also what does it feel like? Mine has just crossed 500 kms - the first tank was Altron X from PSO Ittehad and then second tank is also Altron X from PSO Karsaz. I usually drive in Eco Mode in D and the only thing I hear is the nonsensical rumble from CVT. The engine only wakes up in S Mode, and yesterday I gave it 'some beans' going to 5000 RPM, max speed just above 130. So far I don't get any hint of knocking or pinging.
