I have a air con leak, which is around a sensor of some sort on the o/s lower engine bay, this sensor is in a air con pipe and the wiring is all wet, however, the surrounding pipes are also wet so I'm not sure where it is coming from, I just wondered if anyone else has had the same problem and if its a common issue?

I had my a/c compressor replaced due to a leak under warranty.
However I didn't diagnose (or even notice as I was still getting ice cold air), VW did and replaced it.
Maybe it's the same for you?

Well I pressurised it earlier with nitrogen on the ac machine, and found its leaking past the body of the sensor on that pipe, off to vw tomorrow to see how much they will sting me
