Bought this 2005 325Ci convertible 2+ years ago with 87K miles on it and I love it. Had to replace an internally leaking rear view mirror. Other than that, it's been perfect and I love the car, especially since we moved to FL. I had the car shipped and the first day I drove it in FL, the A/C stopped putting out cold air. Brought it to a local shop that specializes in German cars (the nearest BMW dealer is 40 minutes away) and they diagnosed a bad Schrader valve which they replaced and then recharged the system adding dye. When I picked the car up, they said to bring the car back if I have any problem with the A/C and they'll fix it for nothing. Sure surprised me. I looked in the excellent set of repair records that came with the car and noticed that the Schrader valve had been replaced before about 20K miles before I got the car. Took the car out the other day and guess what. No cold air. There is no sign of any dye around the Schrader valve. I don't see any coolant on the garage floor. I've never had to replace an A/C Schrader valve before on any car. Has anyone got any ideas? I've got an appointment tomorrow with the same shop and, amazingly, they volunteered that there would be no charge for the repair. The cynic in me says I'll believe that when I see it. All thoughts are welcome. Thanks.
