My 2011 panamera 4s has excellent AC, but when I stop to eat and keep the engin?

What is your question?

After idling for 15 minutes the ac in my 2011 panamera 4s only blows hot air, not cold. What is happening?A the AC man hooked up the two valves to gauges and said the condenser is not working. He could not put any Freon in. The car makes a clicking sound.

What makes this problem better or worse?

Nothing

How long has your 2011 Porsche Panamera had this problem?
