I, too, get the "Too low" and air fault. It's been in the low 30's F here. To check I squirted some soapy water on the front struts' air connections and got nothing. Then I just dumped some water into the center circular opening of the shock tower and WOW bubbles galore! I did it to the other side and got them there too. Also, when I tested today the temp was high 40's so the compressor pumped the car up OK but the ride height kept dropping and the compressor would come back on, over and over. One final note: I did hear an air hiss from the are of the right front strut (not the compressor) but only after it had filled up, not while it was filling.

It this confirmation of air bags/seals leaking or could it be anything else? I'm new to this air suspension stuff.

As usual, thanks for the help.

 

You have found the leak, it should be possible to fix the connection you have leaking

If it just the connection and not the bag it should not be a big deal
Easy way to check the bags is to remove the line and connect a temporary line going to a Tyre valve.
Pump up the airbag ans see if it stays up

I keep a set of snap fittings in the boot, just in case
Worse case i can just bypass the system and pump up the bags at a service station to get home
Have never needed them but to me its like have spare fuses

If the air bubbles are from any place other then the air line fitting......you have to replace the air shock. I had the same problem, air bubbles from the top of the shock assy....not the air fittings. Replaced with Arnotts. The cold temp contracts the metals which in turn...lets the air escape (The airbag most likely has a hole or is worn/torn).

 

Spare fittings, clever idea. My leaks however do seem to be from the main body same as Reyesl's. Looks like I know what I want for Chrirstmas. Thank you guys.
