I put the Arnotts on mine 4 years ago up front and recalibrate. Been good ever since. I think they sell both rebuilt with new bags, and brand new assemblies.

Maybe since your struts are in excellent shape - I know you are pretty handy, might consider just putting the new Arnott bags on your front struts and rebuilding yours.

Also, what error are you throwing in EHC module? Mine were leaking for a while and I ended up having to replace the compressor since it was burnt out from being overworked keeping the front struts inflated.
