AC gradually loss refrigerant, should I replace the compressor?
#17
Is that different from the super leak stop they sell separately that may jam the AC?

That leak sealer stuff is all the same. It makes the o rings swell. I've never had it really stop a leak for me. I'm not so sure its harmful either. When people say stop leak it makes me think of the coolant system stop leak which is very harmful.

Mine is at the dealership right now waiting on parts. Quit working last summer and they recharged and added dye. Not working again this summer and they said evaporator had a slow leak. The "kit" to replace the evaporator is coming form 4 places including Germany. Unlike Mass. I need AC in Louisiana.

It's leaking out *somewhere*. Figure out where that is, and then start replacing parts. You m If they put UV dye in it, grab a blacklight and look at every AC line you can. The dye should light up bright green under the blacklight.
Start in the engine bay and look at all the places where lines connect, then the condenser (might have to pull the bumper cover). Jack the car up and look at the underside of the compressor. Check the air vents in the car too - if you see any green UV dye there (imagine a mist), suspect the evaporator.

What year is your car? Mine is a 2018 e-Hybrid and I'm faced with the same problem; car is at the dealer and after recharging, and putting in the UV dye, they've found 2 areas where the leaks are and have recommended replacing the lines. No idea of the cause, car is driven year round (mild Canadian winter in Ontario) and parked in the garage. Very frustrating... especially with the heat we're getting this summer.

If you have a leak in the evaporator, you may consider just adding refrigerant on an annual basis to top it off. I can't even imagine what a Porsche dealer would charge to replace an AC evaporator where the dash comes out? I could see it being over $10k.
I had a Lexus that had a slow leak in the evaporator, that was basically the dealer's solution to just add as needed. I ended up just buying some gauges and a can of R-134 and just topping it off when the summer came around. Worked great.
I wouldn't "guess" when it comes to AC. It should be very clear what part of the system is leaking.

Get a quote from an indy shop. The first picture looks to be leaking from the o ring at the connection. Very cheap fix comprising of a seal and refrigerant. I would guess Porsche won’t do seals and just wants to replace the whole line. Can’t see much on the second picture but could be the same. I’ve seen dealer quotes easily twice what an indy euro shop charges.

Agree the first pic, ut could also simply be a bad schraeder on the low side port that's leaking. Like a $1 part that commonly fails. Or could be an O-ring or it's some connection point that probably has a solution. That does not seem to be a failure point where it could be cracked.
On the second pic, not sure if that's at the crimp or the metal line. Or if it's refrigerant oil from the first pic that has dripped down and collected there.
I'm not recommending this as I have no experience (and I can't see exactly what's leaking) but I would try some sort of epoxy before I dropped 4k on some new lines. Dont really have anything to lose.
They make epoxy products specifically for refrigerant lines

Thanks everyone. I should add that it's the second picture where the majority of the leak is present. The first pic was described as a 'slow leak'.
