Hissing From Dashboard When Air Con On

Hi,

Every time we travel a distance more than around town and we are using the Air Con we get a loud hissing noise (sounds like a gas bottle being turned off and on) coming from the dashboard area on the drivers side. The sound lasts for about 10-15 seconds and there isn't a pattern.

We have taken it back to our dealer who said they can't find a problem and after producing a sound recording they said it was normal.

I don't believe Fords would make a car with annoying hissing sound coming from the dashboard, if you have any idea what this could be then please can you advise us.

Our car is a 2011 Mondeo TitaniumX 2.0L TDCI

Thank you.
