the hissing noise is the carbon canister - normal
the ticking is the cambelt tensioner whacking off its stop, common problem that Renault won't do f**k all about, requires a new cambelt kit (you can just have the tensioner adjusted, but again Renault will do f**k all about it)
The reason i know is because i discovered the issue along with Gates uk who make the belt kits for Renault LOL, even Gates were surprised hen i told them so they sent an engineer out who confirmed it
