Air condition on 1999 Audi A8 Quattro

Do you put the refrigerant on the high side or low side. Or can you provide a diagram? Thanks

it's added on the low side but not advised. the 134a is very specific about the weight of the refrigerant; your car is either 750 or 800 grams. to get the best performance from any 134a air conditioning system, it should be evacuated and recharged with the specific amount required.
