Everything is working fine now, except for the leak. I'm not even sure if it is anymore. There was up to 350 lbss on the high side before. Now it more like 150.
The temp dial isn't working now.
Does any of your manuals tell how to troubleshoot that?
BTW if I had nitrogen I would certainly have used it!

DannyM,
Regarding the MBz CD manuals... The ACC systems manuals are actually a series of some 24 "jpeg" files that vary in size from a few hundred "Kb" in size to several "Mb". Would you contact me via direct email [via my FORUM profile] and I'll see IF I can sort out something that might help you.
The link at: http://germanstar.net/126h.htm tells me that your 1984 300SD model's ~$230 "temperature dial" is part and parcial of the "Push Button Assy." so that's the tact I will take in trying to spot trouble-shooting information for you!
These CD manuals leave much to be desired for many of the diagrams are pitifully inadequate and very difficult, IF NOT IMPOSSIBLE, to read! This is but one reason I finally decided to abandon restoration of any fully automatic ACC system IF I knew the cost of parts was going to make it impracticable. My logic is that you shouldn't scrimp on any of the refrigerant containing/controlling components and these alone can be expensive... so when you see OEM control components that cost $200...$300... $500+... well the notion of using a small number of more reliable salvaged manual system components becomes more and more alluring to me!
Like I think I said before... I'm entering phase III in the complete conversion of a 1980 ACC [SERVO] car... conversion to a 1990(s)-1980(s) MCC from 240D cars... but the entire refrigerant side... compressor, condenser [parallel], R/D, expansion valve, and hoses [4 instead of the OEM 6 hoses]... all of these will be new... and for the EVAP, I will soon be flushing it both internally and cleaning it externally, all without removing it from under the dash!
