I've had the same problem with mine for a while, and not bothered to get it sorted - Regassed today and have a similar leak under the airbox - removing the belly pan for investigation revealed the two compressor hoses (the metal ends just under the airbox) are rubbing - there was a small piece of foam between the two (I've had the car from new and never had any AC work carried out so I can only assume that this is the factory 'bodge' to stop the pipes rubbing together) which has moved, and there is now a small hole in one of the compressor pipes where the gas escapes from. I've ordered the pipe (has to be shipped from Italy), and hopefully it'll be fitted next week.
The noise of the escaping gas was very evident, as was the cloud of vapour escaping from unter the wheel arch!!
I'd suggest taking a look there - could be the same problem..
