Wired sound from passenger side 2018 2.0TDI 190HP

Car - Škoda Superb, 2018, 4x4, 2.0 TDI, 190 HP, 180k km.

A weird sound is coming from the passenger side. I can only hear it when the engine is cold. When it warms up, the sound goes away. All the belts are new, and the sound is still there even when the AC is off. I have checked the rollers, or however you call them, where the belts run, and they run freely. All the parts have been changed to INA belts and so on. I have not yet pinpointed the problem, but many Superb drivers have the same sound, so it's weird.
