Fresh Air intake temperature sensor (G89).... Where is it

[Artea]

Afternoon all, 

So my 07 plate A3 I purchased recently didn't have working AC.

I took it to a garage to get regassed and was told it didn't work.

I then took the car to a mate who ran his diagnostic tool over it and got the error see in the attached photo.

Can anyone give me some clear directions as to where I can locate this sensor as iv done what I feel is a good search and don't seem to have come across it .

 

Originally I thought it was the one behind the glove box, but after replacing that, I found out, that it wasn't that one.

Any help would be greatly appreciated!

 

Thanks,

 

Ricky

I would look between the intake under the scuttle trim and the interior fan motor. That would be a typical location the sensor you are looking for would be situated. Will be a very basic 2 wire sensor. -50 usualy means sensors has failed/disconnected or broken wire. You can use a jumper wire to quickly test for a change in readings to ascertain it’s the sensor needing replaced
