So I've been trying to research for the last week now trying to figure out which a/c pumps off other audi engines I can buy to replace mine that has recently failed. I am trying to purchase one from someone that is parting a car out, or else i would just be buying one for my exact model. I have came across different sites that say different things. Can someone point me in the right direction or just flat out tell me so I can just buy one Already?
