Hello Everyone! I am new to the site, please go easy on me!

I finally have another Audi and have been getting it ready for this winter.
This is an 06 S4 that I am trying to revive from being slightly under appreciated.

This 06 S4 has the Corsa Exhaust and the Catalytic converters have been removed.
I have replaced the rear O2 sensors. The previous rear 02s had been frayed and cut. The rear 02 Sensors have spacers.

I am hoping to get some direction on these codes, I am super frustrated and feel better discussing before throwing more parts at it.

Here is some data. Please let me know if you would like any more.

Mode 03: Emission related fault codes

Interesting that there are faults for both sensors on Bank 2. Have you pulled the plugs to see if perhaps Bank 2 really is running rich for some reason?

Thanks so much for the quick reply sir! I am going to be pulling the plugs this weekend to install new ones.

I am going to look at the condition and compare to bank 1. I wasn't sure if this was super common on cat less cars. I was in doubt this was a result of no Cat when I saw the code for sensor 1.

Maybe the fact the spacer is set at an improper angle than stock or water pooling causing an amplitude that appears to be a diluted reading and causing both codes or even a slight vacuum leak?

Remove FOD and install stock programming is an option?

I really want to check for a vacuum leak this weekend. I dont have any equipment to do that but im sure I can figure something out.

When I pulled both downstream 02 sensors, they were backed out by many threads, almost as if it were intentional.

I apologize for noobing out too hard but what is FOD?
Do you mean install back to stock and then go from there?

Thanks so much jack.

No problem OP, did you know I'm the resident asshole, but in a nice joking and loving way? :p

Did you JPPSG yet?

Maybe this is why in RED below?

I do understand sometimes there really needs to be the resident asshole haha. Its probably super common for people to hop into a message board with hopes of other people doing all the work with minimal effort the OPs end.

I read through the JPPSG guide, super professional. I felt posting my thoughts would open a bit of dialogue to get my gears turning. I do all my own car work but am still learning the data side of diag.


About the downstream 02s. The old ones were backed out but upon installing new Bosch 02s, I fully tightened them into the threads.

Perhaps backing them out will help, I usually refrain from hack-type solutions.

Yeah me personally I don't believe the deletes are very helpful compared to doing a repair correctly.
The CAT cleans up the rear OXS by exothermic reaction and when the amplitude drop isn't seen between the forward and rear OXS you get stupid problems with spacers. Also the rear OXS is superior for mixture control, however, the tuners remove it to get rid of CAT but negate the heater circuit most of time due to laziness.
Did you check the N80 isn't dumping fuel or an air leak too?
In cases where programming and things are altered, mechanical tests will be far more a reliable means than the OBD since it is impaired for VCDS to only show what ECU spits out.

I will have to check that valve, I had those fail in both of my b5s but they threw a code .

Is there a definitive way to tell if my ECU was programmed?

again, thanks a lot for taking the time. I hope to learn quite a bit.

Hey dudes! I apologize for going quiet for a short time. This is not my daily driver and have been busy with my Fiat 500turbo :thumbs:

I checked the EvapPurgeValve (n80) and it was completely shot. It did not hold vacuum at all, I felt no resistance whatsoever introducing vacuum to it.

I replaced it with a ghetto AutoZone part ($40) for the time being as the local audi dealer was closed and then had to order it.

Here is the autoscan after Clearing Codes and running for 5 min.
