Silly Air Suspension…

Bought a 13 Xmr 1000. Of course the air fault comes up. Cleaned the electric connections and sprayed wd40 in the inlet line. Pulled acs module and didn’t get any water to come out. I did not disassemble as it looks likes its sealed up. Anything else to check? Fault usually comes at 35mph when it wants let air out. Need to get the Speedo healer yet.
