The tech evacuated the system and recovered 50g of refrigerant. Ok, well how much should be in there? 900g!!! They vacuum tested the system and it held for 4 minutes without issue. I asked if the vacuum PSI and the pressure in the system when it’s running during normal operation when appropriately filled, are the same. The advisor did not know.
So they put a UV dye into the system and could not see any sign of leaks. I am due for a 1 year service in 5 weeks and they will again check for leaks. I was told that using the ac will put a load on it more, so I will be driving with ac.
I talked with an ex-Porsche dealer tech at a local PCA meeting about this. He has about 13 years experience and said that he has seen hoses leak in 991.1 cars.
The grill inserts are so worth the money for some extra added protection and piece of mind.
I'm really surprised there hasn't been more radiator damage reported on the forums.
I just get leaves in there. Radiator damage is usually flattened fins, like ever since we can remember on any car. Efficiency reduced but unusual to penetrate the tubes,. The add-ons look like home depot things to me.
Update: was taking the car into the shop on Friday and decided to turn on AC. It was 73F on Friday and with Max AC with recirc was getting only cool air. Foreman took the car to assess and said car is low on refrigerant for sure. They checked the lines under the side under panels and it looked good. They will look deeper on Monday.
About 15 months ago, car had same symptoms with squeeling on AC use. Ended your having only 50g of refrigerant. They put dye in the system and sorted in out. On 2 separate occasions, I had them check and all was supposedly good.
Since the dealer put dye in the system approx 15 months ago when they initially refilled the system because the car was low on refrigerant, they were able to finally find the leak. The leak was at the suction hose adjacent to the compressor. They continued to look for other leaks and found none. Hopefully this brings this chapter to a close.
