2008 Disco 3/LR3, Air suspension trouble solving help requested. Upon first approaching the car, it appears almost at proper height on all 4 corners. After start up, air pump remains on for approx 5 minutes. Upon stopping the car, after 2 minutes, an audible sound of "whosh" occurs. It's air releasing from the car. Next drive pump comes on again. Any thoughts on how to troble shoot/fix? Thankyou1
