W210 A/C Actual Values Question
 

My Actual Value, #7, Refrigerant Pressure in Bar, reads 08.

Is this 0.8 or 8.0 bar?

Thanks!

That is 8 bar...system requires 2 bar to activate compressor.

WHEW! This means I am on track to just replace the clutch as my compressor isn't seized/shelled out. I can rotate it by hand at the outside clutchplate.

Any idea why the circuit would be designed to have @6 volts at the coil at all times (EC button activated or panel displaying OFF)? I get 13.5volts when I turn it on or turn off EC (activate compressor).

If you take resistance at the coil (my coil is open with no continuity) to be 3 ohms, it's consuming 2 amps (dissipating 12 watts) so I guess it wouldn't be heating up too much. Could it use this information to throw the code for Electromagnetic Clutch which I have?

Thanks for the reply!
