Thread: Audi A3 Air Duct Sensor Location & VCDS G89 Sensor reading -50 degrees

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.

Cheers

Tony.

I have the same issue wandering if anyone has any input ?
