Hi all I'm in the process of changing my transmission fluid and filter and am trying to identify which fluid to use. It's a 6hp19a tiptronic Quattro box and all the information I've found so far suggests that the correct fluid will be dictated by the current software revision and the only thing I can find with VCDS that looks like a software code is 0070. Can anyone please give me any pointers as to where I can find what is definitely the software revision and also what version of software is the latest available for my car. It's an 2008 A4 b7 cabriolet, 3.0tdi Quattro, ASB engine with 6hp19a transmission. Thanks in advance for any help.
