On the Karoq, that centre display is the MFD/trip computer, and the options are normally changed using the controls on the steering wheel or the buttons/rocker on the wiper stalk, depending on the exact wheel setup. The garage may simply have changed the display view while resetting the service information. For the brake fluid, I’d be a little more cautious about relying purely on a fluid test. Brake fluid absorbs moisture over time, so age is relevant even if the level and appearance look fine. If the manufacturer's schedule calls for replacement at that interval, I’d probably follow it rather than treating it like a “top-up” item. The pad rattle is a different issue. If there’s plenty of friction material left and braking is normal, it may simply be pad-to-carrier movement, but I’d get the garage to identify exactly where the movement is before replacing anything. A good quality pad with the correct hardware can make a noticeable difference.
