No, the original cap is long gone. I do have a reasonably not terrible
solution that only loses about 1 drop of water per every 10 minutes. At
this point it's become a puzzle I'd like to solve! VW lists 34mm and 35mm
as their options. Clearly I am not the only owner with a tank that takes an
unknown thread size.
