Arnott Industries for replacement bags - Last I recall they are around $220-ish for the pair, delivered.


Do you have sports package? If so yes you will need the "sport" rear air bags - The non-sport models and all EHC2 vehicles (including 4.8iS) need the "comfort" rear bags, because of the articulating suspension on the 4-corner air models.


I would replace the bags first and then see - there is a *chance* that the compressor does not need a rebuild, however, if you've been driving on leaking bags for a while the compressor is overworking itself trying to keep inflated, it does not take long.


What the module sees is a filling spec from the compressor, once it gets "tired" or worn out from continuously trying to keep leaking bags inflated, it can no longer fill the accumulator within a certain spec. Then, even if you replace the bags and it will hold air, you still will have the fault on the dash.


If the bags are replaced and no longer leaking, and you go into the module to read the error if the fault remains on the dash, and you see something along the lines of "Accumulator filling requested pressure remains constant", then you need to rebuild the compressor and then reset the faults in the module.


It doesn't "turn off" so to speak, its either operating as needed in normal operation (filling of the tank when needed), or its working constantly when the vehicle is running because the air tank is filling the bags and the compressor is needing to keep the air tank at a certain pressure.


If that makes sense.
