R 55 n12 b16 120ps ps 3 annoying problems.

Hello everyone, wish everyone a happy new year. My daughter’s mini still has a few quilts and maybe someone can help me put them off. The first is apparently the friction roller for the water pump. It probably causes a loud noise which is quite unpleasant. During the ride this sounds like a motor fan, a defective wheel bearing or simply loud tire noises. The rolling comfort of the Allweather Runflats is miserable. I am loading up a video because of the noise and maybe someone can judge whether it is definitely the friction roller. (has become just a link) https://youtu.be/ahPhq3Uke8I had exchanged the wedge belt with tensioner about a year ago and had omitted the friction roller. TÜV was also due and since then the car has driven 6000 kilometers. The loud noise is disturbing but otherwise neither oil nor cooling water loss is present and there are no errors. Second problem is air loss front right and back left so that the wheel is not able to light it up.
