Three questions about Cooper S (Bj. ’02)

Moin people, I’ve been driving my Cooper S (Bj. ’02) for about half a year now! I’m actually very happy! Just make a hell of a fun thing! 1. Question: My passenger seat cracks when jmnd. sits on it! It’s about the leather seats with seat heating. When I drive over a bump it cracks as if a screw or the like were banging against the shell. Isn’t it quiet and really annoying. Anyone has had experiences with it? What could it be? How to fix it? 2. Fra ge: My gearbox cracks or scratches while switching. You can only hear it from outside. And the gear lever “scratches” just a little bit while gearing. Gear oil? Or can it be something else? Someone with experiences? 3. Question: When I have the climate on, every time I stand up the engine fan goes on and turns full pulley. When I start again it goes out. I know this also from other vehicles, but not EVERY time I stand :/ With my old Punto was It’s the cylinder head gasket. But the engine temp also fluctuated. That’s not the case with the mini! Someone would like to know if this is normal? I would like to thank you very much for your answers! MfG Chris
