Any chance you might drive it over to Seattle to have it checked out there
before purchasing?

From my own experience, I had to ask VWOA for a certificate of
NON-compliance to get results, they feigned deafness/dumbness when I asked
for a certificate of compliance. Thing is, it states right in the door jamb
that it complies. Go figure. You can change the speedo yourself, but the DOT
will want an authorized VW dealer to verify it is done. Make sure to swap in
a Syncro speedo, of course. You will also be asked to swap the brake warning
indicator for the US one that has the word 'brake' printed on it.

Looks like a possible head gasket leak beginning, or maybe the pipe above
the left cylinder head.

Sounds normal.

Good luck!
