Vauxhall Meriva sounds like air coming from underneath car like the sound of letting a balloon down

Car: Vauxhall Meriva
Variant: 1.7 cdti
Model Year: 2010
Last couple of days I have started the car and there has been a sound on the right side inside like the sound of a distant hoover! Also on the outside sounds like air coming from somewhere like the sound of a balloon been let down.

Without hearing it , hard to advise . One possibility is the engine regenerating which it does every so often and when it's doing this it causes engine sound to change , cooling fans to come on amongst other actions .

From what you have said , the only thing I can think off is the noise of the parking brake operating .

Deffinatley not that,only way I can describe the sound is lots of air escaping from a balloon or the sound of an oxygen mask

Could possibly be a noise from the turbo or a hose .
