    Your high pressure fault may be with the condenser cooling fans.
    If there is not enough air flow through the front rads the system pressure will build, normally the fans will kick in and cool the condenser and reduce the system pressure.

    Too much and the pressure switch will switch off the compressor.

    Check the amount of gas in the system as well.

    You may have a electric fan not working, or maybe a build up of dead insects or general crud reducing the airflow through the rads.
    As the pressure tests are carried out when the car is not moving the airflow is reliant on the cooling fans, this will highlight the problem.

    And take it to an A/C specialist, do not let Halfords anywhere near it.
