The original is a copper flat washer, part number is the same as you noted
below and is the same as N0138492, which is an acceptable alternative (itsa
teensy bit thicker).  I have on occasion used the air cooled variety copper
"crush" washer without leakage problems - Part # N0138152, never re-use them
of course.  These are more readily available from your local VW shops (Size
is 14idx20od for the flat or crush size).

Hope this helps
