But have you disconnected the pump connection to see if you still get the code? As I said, mine is disconnected and I don't get a code, the only code I got was for the SAI Solenoid valve on the intake manifold before I replugged it in.

No I haven't. I guess I will unplug the pump or solenoid, reset the light, and drive it and see if the codes come back. Does it matter if you disconnect the pump or the solenoid?

I think the code only appears when the ECU tries to turn on the pump. This is why I think a resistor might help with that.
I still have the plug for my solenoid valve plugged in as I recall getting codes with it unplugged.
BTW, I still have a good SAI pump if you need one. PM me.

With both the pump & solenoid valve unplugged I got a code for the solenoid. With the solenoid valve plugged in (but vacuum hose looped from port to port on the solenoid) and the pump still unplugged I have no codes, maybe I need to drive it a few more miles to see but before it would throw a CEL shortly after startup.

AFAIK the ECU determines whether the SAI is working properly using the O2 sensor so it is not easy to fool it
FWIW - my SAI pump was left unplugged at the solenoid and I never got a CEL immediately. I did get it after 3-5 restarts though, every time. Plugged it back in and no more CEL and light. Not sure if that experience will help

You do still have your SAI pump? I think the CEL I get is the N112 valve, but the pump sounds a little sick. Rattling noise. At least that was what it has been the last couple of times the CEL came on. It comes and goes. I think that was the code that showed up when you checked on my car.
I still have my pump but there is a chance that it is sold, there is a 4.2 A6 guy on Audizine interested but I haven't heard back from him since last week but I also told him that I was in no hurry.

Took the car for a 40 mile drive tonight and I got a CEL. Thought maybe I would have to eat my words about no codes for the SAI system but alas I don't have to:
2 Faults Found:
16815 - Warm Up Catalyst; Bank 2
P0431 - 001 - Efficiency Below Threshold - MIL ON
16523 - Oxygen (Lambda) Sensor B1 S2
Since I am Catless that answers both questions I think. I still may try the O2 extenders but I'm going to be gone the month of January so I'll plan on getting my Viper tune in February. Funny that I have already had the O2 for Bank1 secondary before but it hasn't thrown a code for Band 2 and they are all new sensors. Maybe a tolerance issue with the sensor of just a placement in the exhaust. They are both opposite each other in the Millteks.

Does this valve just get removed if the said is bypassed with the ecu programming?

If you don't remove the pump, valves, and associated weight why would you disconnect it? Thing 1 is all stock....Thing 2 has the SAI delete with the 034 blockoff plates. Thing 2 had a CEL the first hundred miles or so, but hasn't come back.
I removed EVERYTHING, installed block-off plates and had SAI coded out by my tuner. NEVER had an issue, drivability-wise, emissions-wise, or code-wise.

Thanks guys. I removed the pump. Egrs and all piping. Installed the 034 plates. Getting it codes it with tune. So tttboost. Are you saying yes to removing the switch? I can't remember it's title. In on my phone.

Sorry correction.... it just came to me....I DID leave my SAI solenoid plugged in...but only so I wouldn't have a connector just laying around collecting crud. If you are coding it out, you can disconnect and remove solenoid if you wish.
