    having recently bought the above car, i don't know the history of the AC servicing
    altho EVERY single service has been an AUDI agent and in accordance with the
    schedule, all i've had a read through and coulndn't seem to find a definate answer.

    the ECON light goes off and on when pressed,
    i have no access to a vagcom, and refuse to goto the STEALERS for a DIAG CHECK


    I don't get cold air (60'F) or anywhere near, like i use to in previous car, i have a
    temp probe in the vent constantly so i can monitor the AC, i use to work for halfords
    and they did an aircon Recharge kit for somethine like £30m with a gressure guage
    on the "recharge pipe", i had the AC running the other day and it was reading very little
    pressure and the air in the car was ever so SLIGHTLY cooler yesterday ( it was 26' in north wales)
    any ideas what it may be... i'll be checking the fan in the next hour or so and shall report back,

    to ruther update, i by passed the ECON (switch under the bonnet) and got the clutch to work,
    seems that there is no power going to the AC compressor, i bypassed it and the central "hub" was spinning with the pulley,
    any idea's what RELAY is connected to the AC system, so i can check it works, or get a replacement.
