Noise from gti engine

[DKPOLOGT]

Hi guys.

Any bid on where this sound (knocking) comes from?
It’s loudest around 2000 rpm if i feather the throttle.

There are no bad sounds at cold start.
The knocking is also not present when the enigne is started and in “cold start mode”.

Direct injection is pretty noisy. Swing past VW if you're really concerned. Or compare to another one.

BMW Vanos makes knocking noises (barely audible) at around that RPM, so not impossible.

All good fast motors will be noisy & clunky at low speeds, cold start , etc.
But thay go reel good when warmed up proper. Listen to a drag racer when it starts up(ugh), but when warm is awesome.
And can fup easier
That's how motors go !!
Want a quiet, super reliable bot OK engine, then get low tech motor. Maybe something from Asia. But sacrifice fun/performance.
Your choice...
