While I had the engine out of the 05 E320 I replaced the a/c compressor and dryer because of the compressor pulley bearing noise issue. I did not purchase the compressor from MB which may be my first mistake? Anyway, did everything right and even vacuumed the system for 24 hours before charging. Now, the compressor does not seem to be working. Pressure on both sides is at a little more than 100 psi with the applicable ambient conditions. I hooked the Autel system up to it and it is indicating the compressor is drawing 2440 mA. The upper range on the Autel is indicated at 750mA. The only climate control fault code is interior temp sensor fault code but I'm pretty sure that was there prior to starting on the car. The a/c system worked fine before I replaced the compressor. My first thought is that the mA load is preventing it from working properly. The auto light stays on on the pushbutton unit and the blower blows like it is supposed to when it is working properly.

Worst case I'll hook SDS up tomorrow and dig in to it a little deeper.
