If the system would not accept the recharge it sounds like your compressor is not running. That's probably what the red blinking light is indicating or the system is low on refrigerant, or both. On our older W210 E-Class the EC button evidently behaves like your A/C OFF one does.
You have a W211 E-Class and there is a forum for your series. Try scrolling down to the sedans section and you will see it. Maybe those owners will have some more ideas.
