Can anyone tell me where the low pressure sensor for the A/C on an '05 R53 is? Pretty sure my daughter's car has a refrigerant leak and has fallen below the minimum so the compressor won't run. I suspect this because the a/c was getting less and less cold over a couple of weeks before it stopped entirely. That said, if there is a leak, I guess she's going to have to get it diagnosed anyway, since I doubt the A/C Pro type replacement 134 with leak stopping actually does much leak stopping.

One other thing - it's probably not the low-speed fan resistor for two reasons: 1, I just replaced the whole fan, including the resistor. 2 - the decline in a/c performance prior to stopping.

sensor is in the line under the fuse box on the drivers side of engine compartment.....

Do not put sealer into the system...

Thanks. Is there an easy way to remove the fuse box, or do you have to remove the airbox and all the paraphenalia that goes with that, including disconnecting the ECU which I hate to do?
