Default 99 E320 A/C hisses

Well, I suppose this is a rant about the fact that I can hear the hissing of the AC (compressor?) during normal operation. I took it to the dealer and he told me that the A/C unit on these year models are located just behind the vents and thus the noise is noticable. Supposedly they got so many compaints that newer E's have the A/C located away from the center vents to eliminate the hissing sound.

However, that is my only complaint thus far -- the car is suberb in all other respects. Does anyone have any experience with this issue? Am I being too picky??

Sometimes this can be fixed by evacuating and regassing the system.

the expansion valve opening must have a very good spray position so as to produce that hissing.

i won't mind it if it's not audible while playing crossover on the CD.

yeah. some mixed of easy listening music/songs. something like toto, earth, wind and fire, hall & oats, etc.

i always make my own CD's because i am working in china and very seldom that they play english songs.

i like music and sometimes get a part time job of folk singing in the bar playing acoustic guitar with midi. i'm paid about $12/ hour.

Here's an update... I've been looking at some other forums about this and they suggested topping off the coolant, so I'll try that. They said if that doesn't work, I might have a leak. Anyone familiar with this issue????
