AC not blowing cold air
Resurrecting this for peoples' information:
2009 E90 M3 with AC problem. Last summer after a horrendous stint of no cold air, I took it to the dealer. They just recharged the system, as they couldn't find the leak. Last week I took it back in to a different dealer after AC was noticeably degrading for a while. They found a leak in the shrader valves of the compressor (the compressor I was assured was fine otherwise). Hopefully this fixes the AC once and for all.
