Hyundai Veloster engine clacks

Hello together, yes I know, I have warranty… yes I know, I drive a Korean and not a VW or BMW…. But I like it. Now to my “problem”. Since about 100km my engine clacks, i.e. I hear it in the stand in the interior. About 15 years ago I had a Golf 2 16V, and somehow the noise sounds the same. At that time it was the Hydropulse… very expensive thing. However, the Golf had 160tkm. The Hyundai just reached 10tkm. A warranty case? Normal that the engine ” louder” or “cracks” ? I drove it up to 5tkm without turning it up once. Since sometimes a little faster on the way. Also 220 on the highway. and as I said, since about 100km the clacking (comparable with a quiet pinning diesel) would be nice who anyone has a few infos for me before I go to my dealer. Greetings
