    Air con button.

    My air con button seems to have packed in. If I press it to turn econ off the light comes back on as soon as I release the button.

    Anyone have any idea why it might be doing it? Suppose a scan will probably be in order.

    No that's what I mean. When I try and turn econ mode off, the light only goes off for a second then comes back on again. Air con doesn't work at all.

    the aircon won't work if the system senses low gas pressure. that's why ecom won't switch off.
    Start with a scan to see if the low pressure sensor is throwing a faults then try a re-gas

    Just purchased a 2.0t Quattro Avant and had the same thing, turned out to be the "thrust senor" or high pressure switch, same thing as bez101 ? about 50 of your hard earned.

    Ok mate. I'm stuck in hospital at the min but I'll give you a shout when I'm out and we can get things sorted. You finish your carbon trim? If not we can swap some bits as I'm thinking of going back to silver.... I have a plan!

    I have the same problem on my B6 Tdi. Will the below method work for my vehicle?
