This is getting rediculous!  Somebody originally posted a message asking
about his "ENG" (sic) light.  I gave him a reply discussing the "EGR"
light (which comes on every 15k miles and is reset by pressing recessed
button on a black box connected to the speedo cable).  Now all I see
is ranting and raving about the "CAT" light, and nobody ever asked
about that.  Anyway, for the record, early (no fuel injection) Rabbits
had catalytic converters and heat sensors: the CAT light would go on if
the converter got too hot.  In 1979 (I think) the emmission regulations
got strict enough that catalytic converters were required again in
49-State models.  But now there is no heat sensor.  I guess the fuel
injection system is precise enought that the converters will not overheat.
You may be interested to know that overheating problems were apparently
common to all cars at that time.  One Detroit manufacturer stated that
the smouldering of the floormat in the car was the warning that the
converter was malfunctioning!
Rabbits without catalytic converters have a "CAT" light on the dash, but
there is no bulb (or socket for that matter) behind the bezel.
