#7 reads ok at 05 cold and 14 running.
I noticed that #5 reads 100 cold and 107 running which I believe from other posts is the evaporator temperarure sensor and have heard that this is way too high and could be showing that the sensor is bad.
At least I have some more information now for when I go into the shop and should be able to persuade them not to just flush the system and run some leak check as the pressure seems fine to me so can't see how it is leaking.
The compressor sounds like it is cycling as it should which I believe shouldn't happen if I am low on refigerant. I also get the same sounds through the vents as I used to when the a/c was working so hopefully it's just a sensor.
