Replace Both Air Suspension in Rear, Still not Fully Fixed
I had replaced the both the rear air suspension with OEM suspension parts (Bilstein) before end of 2018. Now I still see the rear down if I parked it for a few days and it still goes down. After I start the car, the error message: "Do not drive, Airmatic too low" or something like that will go away and I can drive (not at home, working on a Caribbean Island). Then the cycle repeats again. I had taken the car back to the original shop that installed it. Unfortunately, the owner passed away during Christmas. Poor guy. So what do I do now? Is this a serious issue and expensive fix? The car is driveable if I started the car and let the air suspension come back up and the error message will go away. Any suggestions? Thank you guys.

While we obviously have very little info to go on, I seriously doubt that the rear level sensor plays any part in this problem. There is only one height/ride level sensor on the rear, which is mounted in the center of the rear anti-sway bar, and connects to the chassis. I see no way that this sensor could sag or change to lower the rear, then change back to cause it to raise.
I think that the problem is almost certainly due to an air leak. While it is usually possible to find the leak by applying a bubble-making solution to all suspect leak areas and connections, this is not an easy job. The job can usually be made much easier if the tech has DAS (Diagnostic Assistance System), the very powerful and complex dealer-level computer system used to test, diagnose, repair and adjust the car's computer-operated systems, including the Airmatic suspension. It will also be much easier to diagnose if the tech is very familiar with the Airmatic system. Paying someone to learn how to fix your car will get really expensive really quickly.
One suggestion - if you tell us where you are, it is possible that one of the Forum members will be near enough to recommend a shop within a reasonable distance.
It might also help if you became knowledgeable about the Airmatic system.
