Honda coolant is blue now too. I don't understand what the difference is in all these coolants. Anyone know what improvement was made from the gold to the blue? And then there are all those coolants at autozone that say "Universal -- mix with any color in any car" .

FYI, if you have a mercedes dealer near you , you can set up a shop account. They don't require a business license like VW does. And you will save 20% on everything -- a little more easy to stomach and gives you a convenient place to get dealer only parts. I bought a gallon of the latest greatest coolant for 22.00 .
