Here is your answer..
The buzzing was coming from the compressor control valve, the 209 uses a variable displacement compressor, so it was trying to keep up with the demands of the ACC. At full displacement, but with low refrigerant- it buzzes, its not from lack of lubrication. When they replace the leaking evaporator and dryer(which takes about 4-5 hrs BTW, but pays more than that- this disclaimer is to stop all --no way, I can do it in 2 hrs, but I paid 8 hrs BS), and fill the system with the replacement oil (can't remember what an evap adds, I want to say 4 ounces), your car will be fine.
Hope this helps...

Well, two things here-
A- the dryer will be plugged up, it's job is to hold moisture, as any poster mentioned, one drop of water is enough, and you have been leaking for a long time, it sounds like. If refrigerant is getting out, air/moisture is getting in
B- there seems to be a fixation lately amoung techs to this approach to AC leaks- inject dye into the system, fill it up and look for it some other time. I have taken out pieces of systems that literally had dye pouring out of them, so this would also effect flow. Seeing as you are mentioning the smell, it wouldn't suprise me if the inside of your heater box is green (the color of the dye) . Basically, the system is designed for a certain amount of oil, adding dye is exceeding that amount. Once is OK, 6 times..not so much
The control valve is mounted on the compressor on the top, nearest the front

things with and without wheels
If you still have pressure in the system then moisture cant get in there , if the system is empty or it has been opened to atmosphere then you get contamination and moisture .Moisture is introduced into a pressurized system by incorrect testing , servicing or just hooking up gages.

Thanks Guy's. So what do you think is still causing the buzzing from the compressor now that the freon level is correct? RemeMber this buzzing sound began occuring since the car was a just few months old and last year the compressor was changed but the sound came back shortly after. Also the leak was recently detected with a device that "sniffed" freon coming out of my AC vents.
Thanks
Thanks

The evaporators DO go bad. They DO leak. It has NOTHING to do with its location in the car. Its alot more then $400 labor by the way.
MB evaporator problems go back to the W140 and have gotten better since but they occasionally do leak.

Now, Mr. technician, could you give me any advice on how to get a dealer to acknowledge and fix the stumble or hesitation and the long delay and rough engagement of drive after backing out of my driveway (especially when cold) in my 2006 E55???

A 10 oz./yr leak is not a big deal and there is nothing to worry about breathing that small amount of refrigerant. You have already confirmed the leak with the oil smell and loss of refrigerant. As already mentioned, as long as the system isn't flat or restricted to the point that the low side is running in a vacuum, there is no way moisture got in. It's warranty, so give the dealer a shot.

Dealerships or "stealerships" as they are called here are all evil and worthless. etc...
Thats fine... I'm done here. I figured I'd sign up and maybe help out a few people in my spare time. I take pride in my work and training, and take my job seriously. I make sure to the best of my ability that **** is fixed and fixed right. Some people don't, I don't argue that point. But since everyone here knows everything thats fine......I'm gone.
Good luck with your A/C problem by the way. None of my comments were directed to the original thread starter.

Not to sound like a smart a$$, but if a compressor fixed it last time, that was your problem then, and it is again.

Tough decision, take the time to get it fixed or get a new E55 (I know that's not what you said but it sounds good)

[QUOTE=mleskovar]
The 55 is very tempting but I've been waitng for two things; the car to come in from VPC and the confirmation of the lease #'s in writting which I hope to have by today. The CLK 550 is another other option. If the 55 drops out due to the dealer playing games then I'll get the 500 fixed and see how it turns out, if it's perfect I may keep it unless I can get a good deal on a new CLK 550...we'll soon see
