I have some very vague memory of someone talking about how
the MkIV's don't use the same MAF as the MkIII. The MkIII
has a hot wire cycle that it goes through where it burns off
any crud that's collected on it. I seem to recall something
about them eliminating that on the MkIV MAFs, so if
they pick up oil from an open element filter, it stays there
instead of burning off like it did on the MkIIIs. If someone
could could confirm, or deny this directly, that'd be great.
On a side note, my car (with many thousands of uneventful miles on the
supercharger now) lit up the check engine light tonight while driving
around normally. I have no idea why. It runs no different. No
hesitation, no arcing at the coilpack, no smoke, oil's fine, coolant is
fine. Still pulls like a mother in this cool air. Guess it's time to get
the VWTool and see what's wrong. The light has stayed lit thought
one cold start, so I'll see if it lasts.
