Replace the rear air bags, and hopefully you didn't burn out the compressor - It should not sink when sitting, if so there is a leak - if your bags are original, due to age I suspect they are dry rotted/cracked


There is a suspension rebuild kit for the pump seal, which is the part that goes bad - its used on VW air suspension models - if you search "Wabco compressor rebuild kit" it should come up


If you replace the bags and have the error cleared, and there is no leaks or sagging, but the error comes back on and stays, its likely the compressor throwing a code. I'm sure you probably know but you can't "disconnect the battery" to clear the errors on the EHC module, need dealer level software (DIS/GT1)
