So I had this error on my dash for about 6 months now but no saggyness but air compressor is loud and continues to run even after the engine shuts off for a minute. Replaced the bags (easier than I expected) with Arnott hoping they are the culprit but issue remains. Now a new Arnott air compressor is on the way and let's see if that's the issue. Now if the compressor is indeed the culprit and replaced, error needs to be cleared (my apologies if I missed it)? I see threads about it but no mention of it as far as I know.
Cost me almost 1k for bags and compressor yikes

Thank you all in advance!
