End----------(Elapsed Time: 04:58, VBatt start/end: 12.2V/12.2V)-----------

I figured I would start with the MAF. I found a pin out 1-gnd 2-not used 3-5vdc 4-signal 0-5 vdc. with the Maf unplugged the only reading I got was battery voltage on pin 4
is there anything in common with my codes ?
honestly I can't make sense out of the wiring diagrams. I was hoping somebody would have some short cuts. I'll be checking grounds and fuses while I wait for the magic answer.

Some of connectors in "electric box" between passenger compartment and engine bay not connected?
First clear all fault codes in all modules, do a new autoscan and post it here.
P.S. use "code" tags for it.

+1.

Almost all those faults are flagged "Intermittent". They may be residue from having had stuff unplugged while he was working under the dash?

Not all of them is correct but but but.....and clearly FOD modified?
Yeah well I'm wondering why there is a code for front OXS heater and not rear but readiness for CAT & OXS are ready?

Could be a consumer short that is not reflected in the stack is what I'm saying, right?

How about reflash to stock to see what other codes pop up and to an inspection of ECU for burn down inside visually?

What is FP relay status?

Can you perform outputs with VCDS?

Are you sure battery connections are okay and ground points under battery, with full functional ignition switch?

Thank you very much for the well thought out answers. Unfortunately that auto scan was after I cleared the codes. I have no idea of the tune it came with the car. the rear 02 is programmed out. If cleaning up the connections under the dash doesn't clear things up I do have a stock ecu I can swap in.
I haven't tried doing output controls yet. I will also try to figure out what code tags are.

Interesting, is your "known" code out of the rear OXS, a result of some type of "ECM" ( Electronic Countermeasure ) of the possible tuner & for touching their equally nefarious behavior?

That's an idea ain't it Smitty?

Why?
