Ac not blowing cold, new 991.2 1700 miles. Dealer checked refrigerant found to be 328 grams instead of 875 grams, Checked for leaks evacuated system and pulled a vacuum. Could not locate any leaks. Recharged system and placed dye in system in case of further problem. Have vehicle back for several days AC working perfectly. The only thing that I can think of is failure of the factory to properly fill the system during manufacturing. Posting this for comments or anyone else experiencing similar situation.

If you have a leak, it will come back in time. Mine ( 981 cayman) was connected to the compressor).

Doubtful it was low-filled at the factory, more likely you have a slow leak that will show itself again by the end of the summer or so.

Tracer dye will only be visible if you can see the leak. Many areas you will not be able to see.
They should be using an electronic leak detector, sniffing around the compressor, and at every connection point (drier, evap, tev, condensers), and
sniff the vents in the car to check for an evaporator leak.

Actually, what the OP describes is exactly what happened with my car. Failure at the factory. My car had only 50 miles on it at the time. Been working fine ever since.

Maybe not the exact same problem, but with my 991.2 Cabrio I had a failed AC compressor (completely locked) the same day the car was delivered to me. I drove it for 1 hour and had to return to the local dealer for a fix.
