[V8] Audi V8 - we build excitment! (Woes of V8 ownership)

[CB&D, LLC]

You might be thinking of the CAT overheat light that is a separate
light.




Stupid question, but wouldn't an oxygen sensor throw the OXS light
instead of the check engine light?
   
  I mean, what's the point of the OXS light then?

  Hmm.  Methinks it's a OXS sensor problem (or related wiring).  The
resistance values tell the computer to dump more fuel (had it with
the 5-speed), but if the wiring has been cut or somehow compromised,
the correct values will never be obtained.  Instead, you'll be
washing the cylinder bores with fuel, fumigating the cars behind
you, and emptying your wallet.  I'd disconnect the signal (black)
wire from the OXS and see what happens.  Then I'd check fro
compromised wiring and repair/replace oxs sensor.  If that doesn't
do it, it could well be the  temp sensor below the pass side
distributor (but that should give a code).

  Ah Ingo, how right you are.
   
  So, my latest (3000 mile) problem:
   
  I'm driving along, I smell raw, unburned or partially burned fuel,
immediately check engine light comes on, and milage drops to ~14 mpg
at best.  Driving is uneffected, from what I can tell.  This comes
and goes, but in the last 3000, it's mostly been there.
   
  Any thoughts?  

My guess: Engine thinks it is running lean (knock sensor
malfunctioning?) and dumps fuel into the motor. 
   
  This coincided with the changeover to Ethonol "summer gas",
interestingly, and at the same time my cousin's S4 started running
rather poorly (perhaps unrelated, but it wouldn't surprise me if the
gas was to blame).
   
  At 3+ a pop for a gallon, it would be nice to be back around
21mpg, but not if it's a 1,000$ sensor.
