    Hi everyone, does anyone think they could do me the favour of looking over my fault codes and give me any guidance as to what I'd need to replace?

    The main problem is that my air con is not working, I've refilled the system with fresh refrigerant etc but the problem still persists. From looking at the fault codes I'm suspecting something is up with either the compressor or a leak somewhere?

    The second is the fault codes that's to do with the alarm system, as for this I have no idea what these codes mean or if its so serious my alarm wouldn't be triggered at all?

    & the last is that my airbag warning light is on, I've read up that this could be to do with the airbag wiring underneath the passenger seat coming loose or breaking?

    Thanks in advance :)
    -Dan

    ok so first off you either have a pressure sensor fault or a low gas pressure (that will display a pressure switch fault)


    as for the rest clear the codes and see what comes back

    Thanks for that Phil, I will do as suggested. Today I tried to refill the refrigerant again, the pressure gauge went up to the green zone so I stopped and disconnected it, immediately though it dropped back to 0 over a minute or so, so there must be a leak!
