What codes remain? That's the important information, the ones logged originally could be unrelated historic codes from years ago that have never been cleared. I expect it'll be fpr control and heater circuit, but doesn't pay to assume.
As Steve says, the code is produced when deviation from requested pressure is too great, so you want to be checking the deviation values. As you have said, it's the difference between what the ecu has requested and what the fuel system has supplied. I don't know the allowable parameters for fuel pressure at idle, but 30 bar does seem a bit much, could be wrong though.
