Colin: I can't convert bars to psi (perhaps you can help) but 7.3 vs 7.1 is too small of a difference to be the cause. It is interesting that it changes but that kind of a pressure change is very small. Also, the readings that matter are the high side and the low side, measured at the fittings. If you get a set of gauges and some long hoses I think you could read this while driving. Have you considered a possible mixing valve issue? Maybe the A/C is working but warm air is being sent to you?
