Where do you refill the refrigerant on a 92 Audi?

Its a 1992 Audi 100 CS. When the A/C is on full, the car does not cool down. The refrigerant type is written under the hood "R134a" so we got that but we can't find where you put it in! Does anyone have a diagram or can someone explain it please? Thanks in advance!Where do you refill the refrigerant on a 92 Audi?Refrigerant DOESN'T get "used up" because the AC is a closed system. If you need refrigerant, you have a leak and you haven't found the leak and repaired it so adding refrigerant is not really the answer.



BTW, doesn't it tell you that YOU shouldn't be doing anything with the AC if you can't even find the proper port.Where do you refill the refrigerant on a 92 Audi?You don't. You pay someone who already has the charging equipment to do it for you, silly goose!



(The alternative is to also go buy the equipment you need for the job, but since that'll set you back thousands it don't make much sense, do it now?)Where do you refill the refrigerant on a 92 Audi?go to the walmart auto center, and they will do it, for a low price.Where do you refill the refrigerant on a 92 Audi?
ac systems leak, its a fact of life. the leak is just slow enough that it passes the regulations. you should head into a shop and have them pull out what is in there and clean that up and then refill it with the correct amount. i can not go into the locations for the high and low side adapters.
