Air conditioning upgrade R416aUV to R134a i

Hello, dear community,

Since today, just come back from Zandvoort, my climate in the V8 no longer cools, the relay clacks, the speed goes up, the blower gives everything but it comes only warm air :-( I assume that the cold medium is out after two years. The previous owner had had R416a UV filled in and now I am the lucky one who can convert it to R134a. However, I don't find any company that knows what to do. It's not like you want to do it. At Audi there are no retrofit parts they don't want to bring, five others don't want to do it because they don't have any devices (the new ones are probably going to evacuate ) seven others don't want to deal with it :-(

Does anyone know a company or someone who can change my thickness and provide me with the new refrigerants in the Ochtrup/Steinfurt/Rheine area?

PS Would like to make a trip on Friday 17.07.2014 again with working climate.

Best regards
Micah
