Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that report identifying a cause: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Reported cause
Eventually I too had a slow leak that didn't show up with dye, but staining showed it was the most likely cause.

Leading evidence: 'most likely cause' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'most likely cause' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Recommend finding the leak and dealing' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Because the system had lost its gas entirely over a winter in storage, I also replaced the receiver/dryer with a new sealed one and added lubricant as directed in the Porsche workshop manual.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Outcome without a verified action link
I do have 2 new condensers and when the system was filled it had dye added as well, but it’s still not easy to find the leak as it’s slow.

POST 1 / ORIGINAL POSTEROriginal post

I’m wondering if someone might point me in the direction of a good tool to regass a 991.2. I have a slow and hard to detect leak, so it’s best to refill occasionally rather than go overboard searching for it. My device doesn’t fit the valve properly.

POST 2Original post

Can't point you in the direction of a tool, but your most likely suspects in a 991 will be the A/C condensers which live in front of the radiators and are susceptable to foreign object damage, especially if you drive at high speeds. I had a bird strike in my 981 which resulted in a pheasant taking out my offside slats, but I hadn't realised that the condenser had been damaged too. Eventually I too had a slow leak that didn't show up with dye, but staining showed it was the most likely cause. In the end I replaced both condensers myself after seeing the eye-watering quite from Porsche. Because the system had lost its gas entirely over a winter in storage, I also replaced the receiver/dryer with a new sealed one and added lubricant as directed in the Porsche workshop manual. Once all was buttoned up I had the system professionally refilled with the correct quantity of refrigerant and it's been perfect ever since. I strongly recommend finding the leak and dealing with it rather than continually topping up. Receiver/dryer behind r/h panel Old condener removed - site of leak is now obvious New vs old A/C lubricant used in correct quantity to account for 2x condensers and 1x receiver/dryer

POST 3 / ORIGINAL POSTEROriginal post

Thank you for the really detailed response. I do have 2 new condensers and when the system was filled it had dye added as well, but it’s still not easy to find the leak as it’s slow. It could be the pump that the system uses, but this is a hunch and so I’m happy to refill once a year. My A/C Pro doesn’t connect though, so I was just wondering if anyone new of a similar type of low cost system that would work?
