My air suspension workshop and brake pad workshop sensors have been on.... on 2004 Porsche Cayenne Turbo

I bought the car about 1 week ago and already those 2 sensor warning came on, as well as a 'monitoring off' and front left light wanrning.
I looked underneath the car and on both sides, in the mid area at the edge, it looks like oil has leaked out of somewhere...it is dry but i can see it on both sides.
How serious are these warnings that I have mentioned above??

Any warning lights are to be considered words to the wise. What I mean is, those lights are there to protect you and your investment (the car) and you need to get the situation checked ASAP by a Porsche specialist. The warning lights are indicating safety issues and are not to be ignored by a wise person.
