Hello Here in the various forums have read a lot about problems, if the old R 12 air conditioning system is empty and you want to fill it. So, don’t believe any dealer or workshop who wants to rip you off badly. You can and can fill your old air conditioning systems cheaply again, provided they are still dense. There is a substitute for the old ,,, gas , . This is allowed. A filling costs depending on the amount about 50 to 80 EUR. If 0an e4ch tells something else, forget it again snow ll. If someone has problems with the filling up, write to me. I’ll give you an address where you can fill it up. And that’s allowed and released. To finally close down with many workshops that want to rip off a bad one. I had my Calibra refilled today. Without any problems…… Greetings Rainer
