Has anyone encountered any problems with the air con on 306's. I had mine refilled last year with coolant and it worked for a while, but then i had a leak. Apparently there are two pipes which can go. High pressure or Low pressure. I know one is leaking but don't know which one. Is there any way to tell without having to go through the expense of having it filled again only for it to leak? Also my airbag light flashes intermittently, is there any quick fix or is it a Peugeot dealer job? Any advice would be appreciated.
