I like air conditioning; I like it a lot.  When I drive, I drive with the
AC on.  That's just how I roll.

So, the problem for me is that the 2.1L WBX wants to idle at 2k with the AC
on.  Doesn't do it with the AC switched off.  I usually just blip the
throttle and it settles down again, but this is getting to be quite
annoying and possibly not entirely good for my ongoing health.  It's always
done this intermittently to some extent, but now it's really pronounced and
super-double-extramittent.  Can I assume the idle air control valve is
"sticking", or is this more likely an idle relay issue?  I know Audis have
an idle control valve that can be taken apart and lubed up when they stick,
but these appear to be factory sealed from prying eyes and hands.  The van
is getting a TDI swap in the near future, but I would like to continue
driving it in the meantime.  What say ye gurus?
