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.
G89 Air Intake Temp Sensor Location
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.
