so my AC never really blew out cold air it was only somewhat of a breeze in the car and most of the time a warm breeze. Was told by a shop it would be 170 for a recharge. so i just tried out the self recharge bottle of r134, blew it in, and now air comes out soooo cold even when just sitting at a stop. Recommend anyone try that first before getting gapped. haha

Great...can you do a quick DIY write up for everyone...
1. Where did you buy the r134? how much?
2. Where to charge the freon on the car? the location?
3. Any unexpected trouble?
I have a 93 318is but im sure it will be in the same spot on all our cars. My Ac never blew out cold at all now its freezing. I will explain the steps I took to do this it was pretty straight forward. The bottle that you buy will explain how to do this as well.
1. I went down to Autozone and just grabbed a bottle of R134a. There were a few different brands to choose from. On the top of the can there is a hose and then a little connector that kinda looks like an air pump. So get your can mine was about 22 bucks. They also recommend getting a psi measurment device to measure what level the system is at. I bought one but never even ended up using it. That would be about 6 bucks.
2. Drive you car home turn it off so its not super hot inside the bay. Now the location of where the low pressure pipe is easy to locate. On most of the other cars i have seen they are just point out in your face near the battery. On ours look up right against the firewall on the passangers side. Almost right next to your ECU to the right. There should be 2 little pipings that are capped off with plastic screw on caps.
3. The one of the left is the high pressure and the one on the right is low. You want to unscrew the cap on the right pipe. Mine was a bit difficult because it was pushed next to a few wires so i grabbed some plyers to aid in getting it off
4. Once you get it off you your gonna connect the bottle to the port. It is like putting air in a tire. Make sure the can nozzle is locked in with the low pressure nozzle or else when you start adding the can it will just backfire out of the top of the can.
5 Now get in your car and start it up. Then turn all your AC on to its coldest setting you can get on full blast. Let the car run for a good 3-5 minutes like that.
6. Shake the can up well and press the nozzle down on the top of the can to dispense the r134a into your car. hold the button for a few seconds and then stop to shake the can. Keep doing this until the can is emptey and pull off the nozzle. Screw the plastic cap back on.
7. Keep the car running and go drive it around with the ac on full blast. It should be pretty damn cold i know mine was and thats it.See i didnt even check the pressure on my system but if you want to do that for for it I hope this helps anyone who tries it good luck.
I would do that, but my low side a.k.a. the right cap is leaking. Damn I paid like $100 to get my ac recharged damn.. At least now with the leak, they are fixing it and recharging for free, but still, very overpriced.

Got pissed off after getting into a steaming hot car one too many times with no way to cool myself down in after-college traffic.
Went home and dumped the entire bottle into the system, completely ignoring the pressure gauge.
It worked, the pressure was falling at first, but it started falling less and less until it didn't fall at all and just stayed in the FULL zone...
I thought it was kind of weird that a few sprays before filled up the entire system before...
I guess I had a stupid guage before? Either way, I'm cool again! I might need another bottle to be as cool as before though...
(Oh yea, to plug up the kit, you should see two pipe thingy's on the passenger side of the firewall, they both are silver and have black dust caps you can screw off. Theres one with a blue dot on top DO NOT FILL UP THE KIT ON THIS ONE! It will just spray back at you! I took mines back to the store and said the kit was faulty and got a new kit, and tried it on the other port slightly behind it. It's the only one that the kit will fit correctly on.)

Overfilling can not only be dangerous but WILL take away from the cooling efficiency. If overfilled, It can not compress and expand properly. You are actually better off slightly low on refridgerant than you are with too much.
