After not starting car for 3 months. Could it be that BOTH rear air suspension is shot? It has been perfect until now. That seems unlikely to me. It there a DIY way to diagnose? I usually hear about the fronts going out. No lights or balance lights are on & when I started it; it raised to the normal height. Thanks

 

check both batteries. the system is designed to wake up and correct ride height every now and again but it will not if the batteries are low or weak. to be honest i wouldn't worry about a leak that small. when it drops in three days then you will have a better chance of finding it. but the best way to find a leak is to spray the struts and lines with soapy water.
