I have cleared the fault codes for both the DSC and suspension, before (about a month ago), when I clear the fault codes, the compressor will start up and pump the car up. but it has stopped doing that lately, even after clearing the codes. yesterday, I cleared the codes again, I heard the compressor start, but then stopped few seconds after.

I will try and take the abs module out again and send it out for rebuilding. could the abs pump behind the module be faulty? i'm asking because I has the abs module rebuilt once NOT by BBA, by a local shop.
