yeah G12 is the pink stuff. should be no problem as long as what you currently have is pink. if you currently have green or some other color, you'll really need to flush it well. you can pick it up at your local VW or audi dealership

Yes, you can use Dexcool.
It is an OAT coolant and can be mixed with G-12 or any other phosphate-free coolant. I have used Dexcool in my car for 5 years.
DO NOT simply go buy any old "dexcool compatible coolant". It must be a true Dexcool approved fluid like Havoline Extended Life Coolant... The spec requires non-silicated, non-phosphate, non-nitrited formula - basically, no dissolved solids.

Group 2 – coolants based on the organic acid technology (OAT). They contain 2-ethylhexanoic-acid or 2-EHA and other organic acids, but no silicates or phosphates. This formula gives longer life, thus replacing the short-lived silicates and phosphates. Many colors reside in this group. General Motor’s OAT-based DexCool is orange. Volkswagen-Audi has the same formula, but it is pink. Honda has one coolant dyed a dark green, which looks almost black when it is dirty. The corrosion inhibitors in this group are slower acting, but longer lasting. Five years, or 150,000-mile intervals are often recommended in this group of coolants.

ya i went for an oil change at sparkle last weekend because I was running out of time. (otherwise I would of done it myself)
and at the end he topped off my coolant with a universal green coolant, which at first I was freaking out and almost ripped the hose from his hand, but then he said it was universal for all coolants, which is obviously why they have it at sparkle.
Yes, the green stuff is okay, but if you really are paranoid, just go with the G12 to be safe.

Green stuff is not always ok.
You have to know what kind you are was putting in there, especially if you are mixing new into old... If it was glycol based green with silicates then it will not mix well with OAT fluid and will gunk up.
Typically, though, what most call "universal" fluid is the OAT fluid, but always make sure - OAT does come in green as well as pink and can be mixed. Silicate based green cannot be mixed with OAT green.
