Can someone tell me the procedure for replacing the primary refrigerant pressure sensor in my 2002 E320?
Thanks for any help...

The a/c system must have the refrigerant recovered by a machine (illegal to vent out to atmosphere) then you can open the system and change any part. Compressor , evaporator and even pressure senor. After replacing the sensor . Change the drier also(optional) I recommend you add some a/c dye to detect future a.c leaks. pull a vacuum on system . and charge it to specs. Usually located on the engine bay area on right side covers . around 2lbs if had to guess.
