have any of you guys used the redline water wetter? supposed to break the surface tension of you coolant to better dissipate heat.

 

I've used it to nice results in other cars, but I read early on in my AF days that it does not mix with the G12 coolant we use. Don't use it.

 

+1 talked with vw tech and YES DONT MIX WITH OUR G12 coolant bad stuff can and will prolly happen

 

i would really like to here more people chime in on this 1. as it is already in the car. the audi tech that worked on the car said it would be a good idea. hope its not 2 late... EEEKK!

 

G12 doesn't mix well with anything other than water. Play it safe and if the Redline fluid is already in there, drain and flush your system. You'll find the longer you're here that Audis don't mix with very many non-Audi chemicals with good results.

 

i just got off the phone with the folks at redline. they said that they do audi/vw g12 applications all the time. zero compatibility issues. its already been in the car for over a month. no problems as of yet. and i did notice a difference in the heat range of my motor. runs cooler.

 

Maybe you got lucky, keep us posted on the results cause if it works i wouldn't mind trying it out.

 

Agreed there - if you have no ill effects, let us know. I've been told on here and in other places not to use WW because of adverse reactions with the G12, and I'm not going to bet my engine's cooling system on trying it when my car already controls its temperature very well. I've used WW for years and love what it does, but that was always in a car running standard green antifreeze, not G12.
