Hi everyone,

I have only one fault code left in my A2, and it regards the G65 sensor. I have bought a replacement, but now comes the hard part. It is located in front of the radiator, and it is really narrow to get there with a wrench. How do I reach it without taking off the front bumper? Is it even possible?
 
Audi instructions are to remove the bumper. The G65 is located at front top right of the condenser, looking from the front. You should be able to replace it without a refill - there should be a valve underneath that shuts on removal.

Have a look at my post in this thread, I managed to change it without removing the bumper, unfortunately I didn't take any photos:

Air conditioning fault codes

My A2 has been to the local garage to have its air con gassed this morning. Approximately 60% of refrigerant had been lost but there was still lubricant in there and the system passed pressure and vac tests. The system was charged with the correct amount of refrigerant and lubricant and then...

Just be aware (if it is like one of mine) that it might be corroded in situ, so make sure that you can get it to turn without twisting the wee spur off the condenser. Best of luck.

Incidentally - is the valve and threaded bit the sensor screws onto replaceable by someone who is a qualified a/c pipework engineer?
 
From memory, I used a (long?) socket with a long extension and U/J. If you don't use the latter, there may not be enough room for a torque wrench. Torque is 5Nm. Support the connection with a spanner.

Out of my memory (which is hmm) i used a 3/8-to-1/4 reducer, and then various 1/4 extension shafts, and possible also a universal joint. It was tight but not really superdifficult. Good luck.
