Cars been going great until this arvo came up with suspension fault on dash, thought it’s that bloody wire on top of the front shock tower again 2011 4.4TDV8 common fault, but no it’s something else.
Got my Gap tool out searched faults and the below came up, cleared all faults, nothing on dash waited 5 minutes still nothing, car is stuck in access mode, as soon as I try to lift up to normal compressor runs but not as loud as I have heard it (took spare wheel cover off, not compressor cover) ran for 5 seconds then stopped and fault on dash, compressor only gets to 99kpa or 14psi not going to lift anything with that, compressor is an AMK original from new. Anybody got any ideas or something I could check, did a few live values but not sure what to check, cheers everybody

Any sound of air escaping from around the compressor or at the reservoir during the 5 seconds that the compressor runs? Running for such a short time could be due to a disconnected or split pipe. That the reservoir has a little pressure doesn't confirm that the compressor is pumping air into the reservoir, which it won't do anyway until the vehicle is up to the selected height. The softer compressor sound than usual suggests that there is no pressure in the line, so either an open line or the compressor has failed dramatically.
