AC recharge

[mrzeus2012]

has anyone ever recharged their AC? I have a 2005 Cayenne Turbo. I noticed the other day the AC is not as cold as it used to be. Has anyone used AC Pro to recharge their AC? I believe the refrigerant is the same as what Porsche uses. Is this something that a novice can attempt, or will this damage the AC system by using an after market refrigerant that is not from Porsche?

Welcome to RennTech 

You need to determine what is causing the issue before apply any repair.  The correct way to do this is by checking the system operating pressures first using a proper gauge set.  If the problem is not low gas, adding excess can lead to major componet failure and big bucks.  If the system is low on gas, the nest question becomes why is it low? If you have a slow leak, it is only a matter of time before you are back in the same spot again.  The leak should be located and repaired before recharging the system.

 

If you don't have the correct equipment to do this, take it to someone that does.  AC repairs are reallly not a backyard DIY item.

I appreciate your input. quite honestly I have never personally performed any work on my vehicle. a non-Porsche mechanic described using AC pro as simple as putting air in a tire. apparently AC Pro contains sealants as well as refrigerant. thought maybe this would work sort of like fix a flat.

 

I guess you can already tell I'm in over my head, lol. last thing I want to do is attempt what appears to be a simple repair and in doing so cause a major problem with the AC system. my reluctance to proceed in spite of the encouragement I'm receiving from others caused me to shoot this query out to this forum. I appreciate your prompt reply and advice. thanks again.
