Grinding noises at the brake mount from e.g. to the underground garage! Tacho sounds! Howling noises!

Hello dear mini-drivers, I’ve been a countryman S for about 6 weeks and I’m quite annoyed due to many little things: 1. Meal/painting noises from the speedometer are just in front of the traffic lights. 2. Grinding noises when braking downhill e.g. into the underground garage. 3. Howling noise from the engine compartment from about 60 km/h, similar to when driving behind a truck, is not loud, but since it is so high frequency, is annoying. And what the BMW/Mini workshop: 1. Is probably b a my tacho “mini boost…” and with Tacho with Navi conceptually normal, so no exchange. To 2. grinding noise is normal with Mini. To 3. if he cannot explain himself, wants to check my mini again and lend me another comparable countryman, so that I can see if that does not occur with that. Since this back and forth since the purchase pulls and nothing really happens, I will hand the whole matter over to a suitable specialist lawyer Does any of you have anything like that to report?
