This is a long saga,for me and eventually im gonna have to bring my '07 A6 to the shop but my A/C shows a shut off condition of 12. Ive found a definition of the code -----> 12 = Compressor off (shut-off request from Engine Control Module (ECM) via CAN) but what does that actually mean,can I find out more info in diagnostics about it?

Any thoughts appreciated
