    Hi Sorry for the x-post which I had posted in A3 specific section but think it may be better suited for air conditioning.

    Here is my original post.
    http://www.audi-sport.net/vb/new-a3...5719-g89-air-intake-temp-sensor-location.html

    I took the car to my regular mechanic today who is very good with VAG cars in an attempt to replace one of the G89 sensors (3D0 907 543 A)

    I took along my laptop loaded with etka so we could try identify the possible locations that the sensor.
    A few hours has been spent and we are now none the wiser to it's location.

    We fear that it's a dash out job as we need to access the aircon connection box. (1K2 820 353)

    Is there anyone that can help as I fear that I might have to take this to main dealer and pay mucho bucks to rectify a £20 sensor.

    It's deffinelty not the G89 sensors in the outer vents as we disconnected these and checked with VCDS and still the elusive sensor read -50 degrees.

    We found this dodgy sensor after recharging the aircon to eliminate the permanant econ light issue.

    Here's hoping someone knows where it is.

    Cheers

    Tony.

    Check the other thread. It did come to a conclusion.
