Good evening, I would like to have my air conditioner refilled soon, what I have to pay attention to. The Americans use the R10 gas, I absolutely have to take it, or can I also take the “German for us” conventional gas. If you know a workshop fills the amiklimasystem, you can suggest it to me. I am in Ludwigshafen Postcode 670.. I drive a Chevrolet Beretta 3,1 V6 GT I thank you in advance!!!
