Air Suspension Issues-Need Help

[m5biemer]

I'm experiencing some air suspension issues that started with the replacement of the battery a month ago. The front struts seem to lose all the air after the car is parked for a bit, but this doesn't happen every time. When you open the drivers door, the system seems to wake up and it pumps up the front struts, everything seems fine when driving after this. I've read other posts where folks say that the car doesn't drive well, wheel clunking, etc, but so far I've not had any of these issues.

I had a supposed thorough inspection of the system at the local BMW dealer, they came back and said the drivers side front air strut had a leak. I then took it to my independent shop and they cannot find any such leak. I had ordered 2 new replacements from Arnott, but they're still in the boxes. There's no diagnostic message coming up, either.

Also, the system does not want to go up or down when you press the toggle switch on the dash to adjust the ride height. The lights flash for a minute then stop.

Any help/suggestions would be greatly appreciated.
