I had that same problem about 6 months and it turned out I had a air leak. If the compressor turns on frequently then that't probably what it is. In my xp there was a joining fitting that was cracked and was leaking air. I bought this fitting for about $20.00 dollar and was very easy to replace. After that the check suspension light went off.
