Im not a noob in Diagnosing and fixing cars myself, I built my last daily driven TT 03 G35 to 630whp from the ground up almost all myself with just my dad and a 1 car garage.
I am however EXTREMELY new to the whole system and all of the electronic modules that AUDI uses,and considering I just got my vagcom two days ago, Id imagine most wouldn't know much more.
All im asking for is a little guidance of what to look for and what I can do at home. I dont expect anything from anyone, and am most appreciative for every and any bit of help
Prepare to verify!
OKAY then..............Your aforementioned POST #30 ...........didn't look ok when I looked at mine based on scan.
Just which climatronic do you have?
Do you have a G238 in the intake air area of blower motor?
Air Quality Sensor -G238-
Air Quality Sensor -G238- is installed only on vehicles with a Comfort version A/C system
You were speculating here..........on .
G395 is in front of car on condenser.
Are you sure the ground wire is capable of carrying the needed current since 4.0MM .........and not just a tone of the meter continuity tester? ( Current track 59 Junction 368/639 ok? (* T3t1 ) ( PIN 1 )
BUS WIRE Current track 58 from sensor to J519 ( PIN4 ) (*T16b/4) to Junction ( B549 ) PIN 2 (*T3t2 ) G395
Have you observed the work around for this track? From wire being violet to Yellow/green?
( PIN 3) ( *T3t/3 ) Current track 60 to STARGATE 60 to ST FUSE Panel 1 and SC12 FUSE 12a on fuse panel C fuse 12
That would be on a 2010 drivers side left hand drive ST1 panel furthest left of the three.
G639 is in kick plate driver side if you wanna inspect it the other is buried in harness.
What's the poop on the G107???????
There are different versions of the Sunlight Photo Sensor -G107-, therefore make sure the allocation is correct, refer to the Parts Catalog. If a Sunlight Photo Sensor -G107- is installed that is not designated for that vehicle (there is a different signal than the one designated in this Climatronic Control Module -J255- A/C display and control head), the Climatronic Control Module -J255- A/C display and control head cannot evaluate the signal from the Sunlight Photo Sensor -G107- and the A/C system is not regulated correctly.
00797 - Sunlight Photo Sensor (G107)
009 - Open or Short to Ground

Looks like we have fault with a short to ground...........
And then..............So what exact part # did you install for G395 ........hopefully not its look alike G65 with incorrect WAVE
The cooling output cannot be checked when the A/C Pressure/Temperature Sensor -G395- is removed. The Climatronic Control Module -J255- display and control head does not switch on the A/C compressor.
The refrigerant circuit remains closed, connection with valve.
Only the A/C Pressure/Temperature Sensor -G395- may be installed on this vehicle (the data exchange occurs via the Bus), refer to the Parts Catalog.
A High Pressure Sensor -G65- cannot be installed on this vehicle (it only delivers square-wave signals), refer to Parts Catalog.
