Thanks Again All
I guess I was just questioning the problem in that the AC ran great the 3000 miles that I have used the car. (very cold) with no apparent problems. Brought it to the shop and as the car was being prepped for work mentioned in the beginning of this thread it sprung a leak (freon) and with these repairs my cost to repair the vehicle has soared to $4000....but taking into account that I purchased the car for ~10K (with 68000m) maybe I shouldn't complain. I have not had any similiar problems with current other vehicle (1999 300TD-35,000m) or other MBs I have owned (1985 & 1989) and put > 100,000 on. Thanks again all!!
