BS. They are not at all standardized. Use VW/ Audi Pentosin , or another product called DexCool if in a pinch.

you should stick with whatever antifreeze the manufacturer recommends. Those colors aren't there just for marketing purposes; each one denotes a different chemical composition. If Audi recommends that you use yellow or pink antifreeze (which they do for newer models), then stay with it. Remember also that your cooling system will still cool and lubricate itself with as little as 30 percent antifreeze to water content. If you're a little low and need to top off, you can't go wrong with deionized water.
Yes
G12
Always use G12!! You can pick it up at your local VW or Audi dealership.
Have you spilt some on the radiator?
Audi Q7 3.0 TDI quattro: Cooling system capacity (incl. heating) in l approx. 9
A good quality antifreeze mixed 50/50 with water
It goes in the top left tank reservoir. And BTW Audi recommends using G12 coolant, i wouldn't use that green stuff either.
A possible leak somewhere from one of the hoses. Likewise the leak could be coming down the engine firewall. I never owned a Audi. Wouldn't even purchase one.
G12, the red stuff. Make sure there is no air in the system after you flush and fill it.
Flush the system completely. Fill it with G12- make sure you do not have any air pockets.
It has a leak in the Cooling System Somewhere, It might have a cracked Head or a Blown gasket
Recommended coolant/ antifreeze for vw, audi, skoda, seat is G12. Very good coolant, helps, lubricates an works as a anti-corrosive serum.
