Hi All,

I hope someone can help. I have recently bought 2013 Focus 1.6 tdci. As the air con blew no cold air i took it to the garage this morning to have aircon re-gassed. On the drive home the car drove normally (no noise) and was extra cold as expected.

Now in the afternoon, 6 hours afyer having system re-gassed when i i started the engine i could hear a strange 'hissing' noise from behind the sterring wheel area of car. As shown in video link below noise stops when air con is disabled AND i know no longer have cold air. Im guessing a leak somewhere and will retirn to garage BUY can anyone suggest where to start.

The video hopefully demonstrates whats happening:
