A/C issues

All said and told my Cayenne has been in the shop for a month now with two stretches of being home for 48 hours at a time. The issue is the AC, it blows warm, then a little cold, then mostly warm, or not at all.

Most everything has been replaced, the front expansion valve, some lines, some service fittings. Then most recently last week they found metal in the filter from the compressor eating itself. Picked it up yesterday, it worked on the way home from the dealer, but a day later it's dead again.

Anyone had this issue?

Well that was crazy! Porsche replaced everything in the end. It was due to one of the rubber barrier hose sections collapsing on the suction side. It would collapse and cut off oil flow and refrigerant to the compressor.
