Could someone please tell me the VW part number for the correct Autobahn
antifreeze to use.      My local VW dealer said to use Prestone.
I have been using Sierra as it says that its Phosphate free.
I have no leaks and I hope to keep it that way.

Thanks,  and Merry Christmas to all,  Joyeux Noel, Frohliche Weinachten,
Feliz Navidad, usw.
