Hopefully I'm not thread jacking here.

I'm dealing with the same/similar issue. My indy mechanic cleared the code(s) to get the suspension working again, but it typically throws it shortly after especially in the colder weather we're having (below freezing). I'm debating between the rebuild kit you linked to or Arnott's new compressor. Obviously the price difference is substantial ($47 vs. $650). The removal/install of the new compressor looks pretty easy as does the rebuild kit. Can anyone tell me what the advantage of going with a new compressor is or what would justify the added expense? I figure if the compressor functions periodically now and the system holds air (no sagging after having "inactive" code for 5 days) a simple rebuild should be adequate?

Thanks,

Micah
