Matt:
My mistake, the ON reading should be 4.5bar.
At an outside temp of 90F, with the engine on and temp set to 72F, the low side measures 36lbs and the high side measures 100lbs. Starting to sound like a bad compressor, low side too high and high side too low??
The dash diagnostic at 1200 rpm shows (for 07) 4.5 bar?

7.5 bar probably isn't enough pressure to do much of anything, and this could be the problem. Be sure to verify the reading on the pushbutton unit with a gauge on the high-side service port.
The resting pressure means very little, unless it is very low. The pressure that you will see depends on the refrigerant temperature alone, as long as there is any liquid in the system.
