Have you run codes with a Foxwell or real BMW scanner? Why does it say the compressor is not engaging? I think it would be highly likely that the fan fuse was blown, preventing the compressor from running, AND you had a second problem keeping the compressor from running as well. A Foxwell would tell you exactly what the problem is.
