This video is to provide measurements on the factory dipstick 018 321 431 D for 4-speed ZF 4HP24A automatic. The factory plug is 018 321 431 H. I do not know if there are any variations of dipstick tube or transmission types. Take this as a guide as I have only used this in my personal Canadian model 1993 Audi V8 with the 4.2 L ABH V8 and Quattro AWD system. Front wheel drive Audi V8 would likely use a different transmission.
