    MK5 TDI AC woes

    So - my AC stopped working yesterday, sadly a few hundred kilometres from home in 30C + sunshine. (I guess not as bad as 40C and sunny ...)

    My golf has been in storage for about 9 months - started about once a month and AC run occasionally.

    The fan on the AC appears to work fine.

    The thermo/radiator fan now appears to work all the time. Started the car this morning (engine cold) and even with the AC off, the thermo fans sound like they are going as fast as they can.

    Some googling suggested the pressure sensor in the AC could be the problem (and account for both symptoms). Does this sound reasonable? Where is the pressure sensor and is there a way to check it?

    OBD scan gives code 00229 from the AC module - low refrigerant pressure.

    Thanks for your help!
