2005 987 aircon blowing warm, won't take re-gas
Discussion
This happened today. I'm lucky enough to live over the road from a place that could help, and they tried to re-charge the system at short notice, to no avail. So it would appear I have a leak to deal with. In order of preference, I'm thinking I'll start with looking at the condensers, pipework joints, compressor and evaporator. Any thoughts as what I might miss?
A full check over by a competent air-con specialist (not OPC way too expensive) they put a fluorescent dye in which shows any leaks under ultra violet light, I had a very good local guy come and re-gas a car for me very professional and had a wealth of knowledge.
My 987 has just had a new pipe fitted where the gas is charged into the system, the valve was leaking, a new valve didn't fix it so a whole new pipe was required.

This, will pin point the leak in seconds...

The rads gather leaves and rot out .Look for oily stains .
Next up the drivers Jack pad is mm from a couple of major AC pipes .
Porsche use ( available on e bay ) a tiny Jack pad to avoid pressing on this pipe .40 mm ( guess ) dia
Quick fit or others use industry std 120/150mm pads .Theses will compress the under tray and the AC pipe .
The condenser in the scuttle is a £25 consumables , not sure how long something like every 3 yrs .
If you don’t renew it it fills with water and slightly decreases the AC efficiently, but crucially excess moisture runs down that pipe by the Jack pad and settles .
Over time the water starts to rot out from the inside this pipe ( £150 from Porsche ) .
With the flexing from oversized Jack pads and corrosion of the internal aluminium pipe where the excess water settles = hey presto a pin hole leak is inevitable.
This is where you are right now .
Fix .
Bumper off 2x new rads @£50 each after market .
£25 new condenser/ dryer .
£150 new main pipe the high pressure one near the Jack pad and May as well do the £130 low pressure next to it inboard .
Buy the O rings from Porsche .
Be prepared to drill out the old pipe connector bolts as steel + AL + salt = corrosion fast / stuck / won’t move / fracture at the head .
Trip to Quick fit for a £65 refresh of gas .They will vac it all out and check it hold vac ( inverse of pressure ) before refilling.
