RE: Fault Codes for '91 V8

["James A. Desveaux" <desveaux@ucla.edu>]

Ed:  

According to the Bentley (and Scott Mockrey's website), a fault code of 2413
(for the 200 series cars) translates to: 

Mixture adjustment
Adaptation limit exceeded
Symptom: Rich mixture, increased fuel consumption

Even though your car is a V8, I think the numbers on the VW/Audi coding
system mean roughly the same thing for all models.  Clearly, some of the
codes don't apply if, for instance, you've got a N/A car.  You wouldn't get
a code like 4442 (wastegate frequency valve).
