Question about 2005 Mercedes-Benz Mercedes Benz E320 Cdi
After putting r134a in line started car and heard loud noise from ac compressor area. Now I don't have cold air blowing. I thought maybe I put too much refrigerant in the system.but, car started smoking from engine belt and would not start up for the first couple times. Now I can start it just fine but, no cold air.nothing but air in the line now.
Refridgerant should NEVER be added to a system thats not running in on posisition ( says so right on can) , there is a multiude of failures that could come from doing this , belt failure's , hose failures, rec tank opening
evaporator coil openings , pump failures
i suggest getting a professional to look at it to see what dammage was done
remember laws of physics 101: Liquids don't compress but gasses do and it takes very little liquid in a gas system to destroy the parts of system

TYPICALLY this could be because the air bags are leaking and caused your compressor to overwork itself to death. The airbags are not designed to withstand temperatures below 40 degrees and above 94 degrees. Can you believe that!?!? Dry rot starts forming on the inside fold of the bag making it very difficult to detect with the soapy water test. Anyways.. i went through all these problems and several hundred dollars before I finally decided to convert to a passive coil spring system. I got it from Strutmasters.com with a lifetime warranty. http://www.strutmasters.com/mercedes-s-500-suspension-s/112.htm I have been riding on them for about 8 months now and am very pleased so far! I actually now PREFER the coil spring ride to the air ride and was surprised at just how comfortable the ride was. Hopefully you won't have to go through as much money and heartache as I did before I went for a more permanent solution. By the way, my shop only charged me an hour per wheel to install the kit so it was pretty cheap on labor too!!!!

I think that this might help you. The a/c compressor is a continuos running type there is no clutch. It has a wobble plate internally wich changes the piston stroke. Screw the genises machine-it is probably only reading a partial on the climate control module. see if you can find the self diagnoses diagram either from the factory or if you have all data. you can pull the codes right from the unit itself and they will be accurate. If you can,t pull codes see if you can get an actual value of the sensors in the a/c unit. You should be able to pull that up as well if not try the genisis. Look very closely at you evaporater sensers(left and right) you will probably see a -40 degrees-that is the sensor default input reading when the sensor goes open. That sensor is used to moniter the wobble plate position of the compressor.

SOURCE: ac not working on 2004 s430
If you have the hood up stand outside while someone activates your air off and on and see if the clutch on the compressor goes on and off while they activate the switch. If that isn't it the it could be improperly charged system or your climate control door that opens and closes for hot or air is not working properly and only stays on heat.
