I agree with Skinny, the only time a re-gas helps is if the system is not blowing ice cold, but is still cold. If the system has a leak then you must fix the leak before doing anything else. On my 996 their are long pipes that run front to back along the sill- people jack the car up on the pipe, crushing it partially. The pipes then leak, and have to be replaced, but people don’t want to because they’re very expensive, something like £700+VAT per pipe. So they sell the car “just needing a re-gas”.
