At this point, it could be several things. The first thing you need to do is to do a leak test. This can be done without even getting your hands dirty: By far, the easiest way to test for a leak, is to allow the car to vent down after shutting off the engine and opening and closing the door.
IT IS VERY IMPORTANT TO MAKE SURE THE CAR HAS LOWERED PRIOR TO TURNING THE SUSPENSION SWITCH OFF, OR THE TEST WON'T BE ACCURATE!
If nothing else, wait 5 minutes after you turn the ignition off. Then turn the suspension switch off. The car should have vented by then.
After this, turn the suspension switch off and measure the height of the 4 corners of the car with a tape measure and write it down.
Now drive the vehicle for a few days.
If the vehicle has a leak, the car should go down after driving.
NOTE: Depending on the severity of the leak, it may take more than one day to leak down. This is the case more times than you would think.
By all means, if the car goes down after 10 minutes of driving, turn the switch back and resume your journey. You have answered your question.
