I really need help!! My old Transmission Box developed a fault and went ahead to purchase a new transmission box, the thing is my old Box had FEP transmision code and the one i found is FAR transmission. from my understanding the FAR is from a 2.8 T VW Passat. but everything else looks similar on the two boxes. my question is, will this FAR Transmission Box work on my 1.8T Audi A4 without any issues? Please help
