Looking for a ecu pinout
 

Does anybody have an ecu pinout chart for 2001 a4 quattro automatic wit a 1.8L
I work at an independent auto repair shop and have a california smog inspectors liscense. If you have any questions about smogs I am your man.

2002 Audi a4
 

I have a 2002 a4 audi that failed smog. Before smogging the vehicle, I had the following replaced to take my "check engine" light off:

.O2 upstream sensor
.O2 downstream sensor
.catalytic converter (after market)

My check engine light continues to come on. I reset the code about 40 miles prior to smogging. The light stayed off throughout the smog check. However, the smog person told me the reason why he believes it failed. He said, "the MIL/ Check Engine Light did not successfully complete all OBD self tests." Please find an image attached that shows my car's smog numbers.

The code that continues to comes up is, "P0402" which stands for, "Catalyst System Efficiency Below Threshold (Bank 1)."

Any help would be greatly appreciated. Hope all have a Happy Thanks Giving!
