Any advice on the following would be hugely appreciated!
1) When switching suspension to high setting, the tail risies but car won't rise at the front.
2) After a few hours, the car sags slightly to the left.
3) Airbag light is on.
4) Nothing appears to happen when pressing the 'Hydractive' button near the gearstick. Is a light supposed to come on somewhere?
5) There's a metallic rattle coming from underneath the suspension height adjustment knob. It seems to work okay but when twiddling the knob, it feels like something has become disconnected/detached?
I think that's about it for now. If you can shed any light on the above, I would be eternally grateful! Really hoping to start using the car soon - can't wait!

Kindest regards,
James
