The pressure is between 224 and 248 psi sitting here at idle in the shade no heat load. 
That Is commanding the transducer to send a signal to the control unit to boost the fan speed up for more airflow over to condenser to lower the head pressure.
Under normal circumstances in the sun on a hotter day the pressure should be this high and that would be normal operation
But with my experience on the BMW series I feel that this should not be the case with a small heat load without sitting in the sun or being very hot so I’m going to take a gamble.
If I am wrong I will not charge the customer for my work if I’m right I’m going to charge.
Because this vehicle was just recharged by another shop I think it is overcharged just a little bit
