Has anyone used this fluid in a VW or Audi? I just 4 liters of it and when the weather turns better I will change my fluid with that. On my car there is no transmission line to the radiator so a flush that most people would do is out of the question. It has the spec VW part number listed on the bottle and it also says it on the bottle that it is a low viscosity fluid. This is for my 2013 Passat with the 09G. I noticed a YouTube video in which someone poured a small sample and it is clear, it looks like regular oil. Although the fluid in my car now is red, that does not really surprise me as some ZF fluids are green. I got my Top Tec 1800 for around $11.00 and tax at Napa. Many other places are asking for the $24 the dealer sells their fluid for. It was $5 off since I used my phone number when I reserved it. Not bad at all. It came to $41 and some cents total. Not only does this fluid list the fluid part number for my car but it also specifically mentions ZF transmissions too. I have read that they too are sensitive to fluid quality in a way similar to the 09G. If all goes well after using this, I will have found my lower cost alternative fluid for my car. I know it is only a clear fluid because they did not dye it red and it is only needed for identifying the fluid. The only other thing it does is permanently stain clothes.
