need troubleshooting input concerning air suspension

[bcredliner]

I have had a leaking air suspension bag on the right side for a few weeks, left side has been replaced. A few days ago both sides dropped to zero. I checked the fuses (32 107 123), all good. I replaced the bag -no fix. I pulled the piece of shielding under the pump to check it over. Could not find anything wrong. I installed a new pump and control valve--still no fix. I have rechecked all connections for lines, fuses and connections. Any suggestions?

When I first started it up after installing the pump I heard what sounded like a short burst of air the first two times. After that nothing. I couldn't tell where it was coming from. I don't know if it if it had anything do with the air system. Thoughts?

I have a Foxwell 530 scanner for BMWS but don't think I have the necessary modules to test the system or I don't know how to find the test. Do I need to download anything to have the run test?

After replacing there is a calibration fine with the Foxwell. It involves adding and removing 300# from the trunk (set of mounted tires was perfect). I don't remember where I found it prob in service/body.

The best way to find/clear codes is to first run auto scan. If it auto disabled from error you likely have to clear first.

I got out my old Foxwell scanner and went to systems check and went to air suspension test. Inflated the right side and then the left. all fixed. Thanks for the response, happy holidays!
