I have a 2011 A4 Quattro (B8) with a MXW (ZF8) transmission. I bought this fluid for a drain and full along with the filter and gasket. It says that this Toptec 1800 fits my vehicle, but if I look at figment notes, my car is not listed. Is the the proper spec fluid for my car? Please help. I do not want to put the wrong fluid in the trans.
