    The ECON button that controls A/C compressor has decided to stop working.

    Currently the button shows no light which should mean AC compressor is switched on (I havenít checked the MVBís on VAGCOM to confirm this).

    I have confirmed that the switch appears to work as when I press it the fans come on and then turn off when pressed again (however I donít have the convenient light to tell me this).

    So it looks like the LED / light isnít working possibly due to bad wiring or connection? Not sure if LEDs can burn out or become defective?

    The switch works but the indication light doesnít.....

    Any ideas what this might be?

    I would suspect the AC system is empty, start with a code read.

    Itís been regassed......I also replaced the condenser / radiator (the one that sits in front of the main coolant radiator for the engine) prior to regassing as the one on there was original and looked knackered!

    The switch appears to work as I explained before the radiator fans come on (both of them)....and the air goes cold...

    I had a look at the wiring behind the HVAC controls and couldnít see anything that looked bad but would need to probe them with a multimeter.

    Could the gas have leaked out?

    Hopefully it hasnít!

    Is that why the ECON LED doesnít light up?


    As youíve said need to run a VCDS scan see if there is any fault codes.

    Shall report back with scan report.

    A code read will tell you what you need to know, if there are no codes and the air goes cold I would suspect the LED is faulty and it is not replaceable easily.

    So itís finally chucked a code....

    00229 - Refrigerant Pressure: 002 Lower Limit Exceeded

    Ross Tech site says.....

    Code:
    00229 - Refrigerant Pressure: 001 Upper Limit Exceeded
    Possible Causes
    Refrigerant System overcharged
    Cooling Fan(s) are not functioning correctly
    Condenser is dirty or Airflow is restricted or blocked
    Refrigerant System blockage, stuck expansion valve, etc..
    Refrigerant Pressure Sensor
    
    Possible Solutions
    Use a Gauge Set to check Low and High pressures
    Recover and Recharge Refrigerant to proper charge level (refer to vehicle label)
    Check Cooling fans, 'Output Test' with VCDS
    Check Expansion Valve
    Refrigerant Pressure Sensor:
    Check Measuring Value Blocks
    Check wiring, connections
    Check for leak at sensor connector)
    
    00229 - Refrigerant Pressure: 002 Lower Limit Exceeded
    Possible Causes
    Refrigerant System undercharged
    Weak compressor / clutch
    Stuck open Expansion Valve
    Refrigerant Pressure Sensor
    Possible Solutions
    Use a Gauge Set to check Low and High pressures
    Recover and Recharge Refrigerant to proper charge level (refer to vehicle label)
    Check Compressor / clutch
    Check Expansion Valve
    Refrigerant Pressure Sensor:
    Check Measuring Value Blocks
    Check wiring, connections
    Check for leak at sensor connector)
    Also after checking the measuring blocks in Auto HVAC module on VCDS itís in status 3 which means the compressor is off due to low pressure <2.0bar.

    You hover the mouse over the box / reading and it comes up with a description outlining all the status outcomes.

    So Iím suspecting a leak somewhere. Going to get my UV torch out and see if there is anything obvious. (Unless the aircon doesnít have the UV leak detection dye in it when it was regassed last June?

    Perhaps this isnít the case and doesnít have it at all and you have do add it yourself?

    Have read that the pressure sensor is a potential area of concern.

    The condenser / radiator thing that sits behind main engine coolant radiator on the lock carrier was replaced also in last June as was an original part and was passed its best. New orings were used for the pipe that attaches to it.

    Over pressure suggests the sender is faulty or the fans are not running. Change the sender (it's on a Schrader valve so easy) and then check the gas pressure; if necessary get it regassed.

    The first fault code said over pressure, when this happens the sender can burst in the centre and then you get under pressure, the second code.
