[s-cars] Car bucking under WOT - I have codes

[Ian Duff]

Can you find anyone near you with a VAG-COM? It will perhaps tell you more
than the blink codes. Speaking of which, where's "near you"?

Listers,
Thank you respondants for all your help and BTDT, I greatly appreciate it.
I ran the CEL codes and got the following (2 corroborate with other
listers).  Thanks to http://www.sjmautotechnik.com/20vcodes.htm for the
decoding:

2322
Inlet air temp
Open or short circuit
Defective sensor or wiring
Symptom: Slight power loss, Increase in fuel consumption

2222
Pressure sensor
ECU Pressure sensor defective,
Repair or replace ECU

2224
Over boost condition
Waste gate or pressure hose, Waste Gate Solenoid/hose problem

2413
Mixture Adjustment,
Adaptation limit exceeded,
Symptom: Rich mixture, increased fuel consumption


All of these sound pretty bad, but I'm very glad they confirm my initial
estimates and match up w/others experience.

I've got quite a bit more debugging to do, I'm resetting the ECU and will
run the drive test again to make sure I didn't miss any codes.

Has anyone had these codes all together?  Could a bad pressure transducer in
the ECU cause all of these problems?  Or is the 2222 likely to be in
reaction to a problem with the boost plumbing?
