How, may I ask, did the gauge tell you it was properly charged? I've been working professionally on auto AC for almost 40 years and I can't imagine a gauge telling me anything about how full a system is without running. Even then it takes a lot of experience to get close. The only way to know is to pull it out and measure what goes in PROPERLY, with a scale.

Clear the codes and maybe it will work.
