oh we're in trouble now !
Figured you had an air-cooled vanagon has they do indeed have a cold start
valve, and being late on the conversation possibly, you didn't know Jim is
talking  about his 2.1 waterboxer.

but now .......you're saying a TDI ALH engine has one ?
I know the AHU better ..............and , correct me if I am wrong ......but
there are only  4 injectors on a 4 cylinder ALH tdi engine,
and no cold start injector.

yes.........longer injection times, you got it.

A separate cold start injector is just a hokey thing, and old fashioned too,
in my opinion.
I don't think there are any modern engines that have them.

here's a fun one for ya .........I can't remember the model right now
...........but there are now cars .......might be a Lexus ...........that
have both port fuel injectors and direct injection injectors in the
cylinders.  In other words,  16 injectors on a V-8 engine .....
or maybe it's 12 injectors on a V-6.    Gonna be expensive to fix someday if
work is eventually needed on them.
