Is it fair that I have to pay £292 for air conditioning regassing on a 2-year old Hyundai i10? Apparently this model uses the new (and very expensive) R1234yf environmentally friendly refrigerant and the firm's warranty excludes refrigerants unless required "as a direct consequence of a warrantable repair".

The dealer cannot guarantee how long the re-gassed system will work for and tells me that many owners just accept the air con not working. I don't think this is acceptable on a two year old model.
