Hi all I called 2 Citroen dealers near me to find out about aircon regas and clean. 1 said it needs a new type gas and said £180, other said it needs old type gas and said £89. I am now confused. I cannot find anything in the service book to say which gas it takes. it just says it needs doing every 2 years. If you guys know where I can find the right info for my car. Its a 2014 C4. Or if you guys know where to look in the hand/service book. Any help is appreciated.
