2017 S3 will not pass readiness test.

[Elvir]

All,

I just purchased a 2017 S3 stage 2 with IE tune and hi flo down pipe. The car has been driven several days and over 700 miles have been accumulated.

I took in for emissions and the person told me "I got good/bad news!"

Good- car passed emissions
Bad- car failed readiness

I have not cleared the codes nor removed the battery, nor does the car have a CEL, and to my understanding by now, if they were cleared they should be set by now.

Has anybody had this happen to them?

[nick1980]

Same thing just happened to me
2012 a7 ,I bought it outta state so it needed emissions to be registered
It failed readiness because the cars battery was replaced and I scanned the car with vcds and reset all codes and drove it for afew hundred miles
I guess it needs several key cycles and cold starts
Mix of city and highways rpms etc
I went back afew days later and passed

700 miles is plenty to set those monitors. You need to check with IE to make sure their tune doesn't disable any of those sensors. My bet is on the tune disabling some of those sensors that's preventing readiness.

IE fucks with emissions even though they say they dont... They LIE.

It wont pass inspection. Flash back to stock and then you'll pass.

Even their stage 1 does it.

Dont bother talking to their Tech Support... those clowns dont even know what their tune does.

Thanks for the heads up. I figured it had something to do with the tune. I did speak with them and they insisted that I turn the car back to stock and that it should pass even with a hi flow cat. I am waiting to receive the dongle to flash it back to stock and will test after that.

I figured it might be coded out by IE that is causing it to not be ready, as it should have been reset by now.

[Spinnetti]

This is common with most (all?) stage II tunes. Flash back to stock, wait for readiness to set, then retest, and reflash. In my case, using APR DP and Uni tune, I also needed a simple O2 spacer. Fun, but its just once a year

The car isn't the problem.
Why the fuck does your car need to pass any test?

Because some states require emissions and inspections annually... thats why.

Mine passed readiness just fine once I flashed to stage 1 and drove it for a few days.

Just to calm the waters, this is all normal stuff folks.... Just part of the stage II experience. There's only so much the tuners can do.

[Gberg888]

Agreed with Spinni but... most stage 1 tunes pass. That is not the case with IE.

[Elvir]

thank you for the input all. Im feeling better now. I am waiting to get my powerlink to get the car back to stock tune. I did go ahead and just for good measure buy o2 spacer since the hi flo cated downpipe will remain on.

[BCap]

Can confirm. Stage 1 IE doesnt pass. It wont set 2 of the 8 emission readiness. Flash to stock for test and then reflash.

[Elvir]

I got a checkengine light with the catted hi flo down pipe. made it 60 miles with 2 codes to go. I added a 02 spacer and testing now. Still got EGR as only code that needs to clear.

[sbruno624]

You can force readiness through the Output tests with VCDS. You just need to do all the tests for anything related to O2 sensors and Cats. You run the test. It will tell you to hold the brake and floor it. It should hold revs for some but some may just sit there and then it will say complete and the car will ready up. Unsure about stage 2 but this will work for stage 1

Have you tried that? How long does it take to complete the test? Do you need to do all tests or selectively?

passed emissions. I learned that there is a fast track to getting the EGR code co reset faster. Not sure how much of it is true or how much of it is woo-doo, but all good to go.

I’ve done it multiple times. It takes a few minutes once the car is warmed up but I could never get my car to get ready even after flashing back to stock so I had to do this.

Just out of curiosity what is the fast track method? I have stage 1 IE tune and had to flash to stock and drive like 100 miles before readiness reset.

Also, are you saying your are stage 2 and flashed back to stock? IE told me that would trigger Cel which I was concerned would not let me pass inspections. Did Cel clear itself away?

Found a several videos where they mentioned the following: Drive car up to 65mph and let it naturally slow down to below 20mph without touching the brakes. Do it twice and its ready. I did it while checking the reader and it worked. the scary thing is that it takes the car a long time to slow down to that speed. so I made sure i was out in back roads where there is no traffic lights, intersections or neighborhoods.

To answer your second question, yes my car is stage 2. and I did indeed get a CEL when I when I flashed back to stock. I anticipated this was going to be an issue so I had already ordered an O2 Sensor Spacer. After Installing it, I cleared all the codes and it just would not get the last readiness cleared, so I searched online and found several videos about the fast track.

[Elvir]

ok, Looks like I am back at this again. If anybody has any input, please pitch in, but Im mainly using this as a log.

*I detuned the car to factory setting while having a hi-flow cat. I did add a o2 spacer last year which helped me pass emissions. I was able to make it to 60miles.
*Now, I am only able to get 10-13miles before CEL. which isn't adequate enough to pass readiness.
*Two codes that I get are as follows:
-P2270 - O2 Ban1, Sensor 2 (Which I kind of Expected)
-P0230 - Fuel Pump Primary Circuit Malfunction. Not sure what the cause of this is or if its relevant. I do not have fueling problems.

Note, when I got the O2 spacer, it came as a two piece system. One straight extension and one Elbow. I used Straight extension, trying to think if i should add the elbow to push out the O2 sensor further from the flow stream. Not sure if that would help any with the Triggering of CEL.

7/27/2022 Attempt to reset codes
Beginning Procedure
10 minute warm up (5 codes)
-Fuel System Mon – INC
-Catalyst Mon – INC
-EVAP System Mon – INC
-Oxygen Sensor Mon – INC
-EGR System Mon – INC

• Cool Down (several hours)
• Highway 5min (55-65mph), and stop without using brakes. (Reset EVAP at 15 miles in)
• Drive to 45 and stop multiple times, (Reset OXYGEN SENSOR MON at 20miles in)
• CEL at 23 miles.

Get the CTS spacer for the o2 sensor and flash back to stock… run it for a while and if the code doesn’t come back you’re fine…. The only downpipe that supports no tune with the emissions pass is the AWE… but you’re going to pay for that privilege… the easy out is the spacer…

I didn’t read the last post lol…. Get the fueling issue checked out… it may be triggering an automatic emissions cel if the car thinks you’re dumping fuel down there.

I'm not sure what the Fuel code was, but with all this testing, its not coming back up.

Can somebody confirm if P2270 code is indeed the code that pops up due to hi-flow cat. I just want to make sure I'm not chasing wrong things.

7/27/2022
-Removed the straight spacer for 90 degree spacer
Test 1: Made it 13 miles before CEL
Test 2: Made it to 23 miles, driving very casually not to emit too much emissions. all IM Readiness codes still active.

Note: If CEL pops up again, I will add the straight spacer to the 90 degree spacer to push the O2 sensor even further out.

I was under impression that these spacers would keep the CEL from coming at all, but so far they don't seem to be helping, which is the reason i wanted to confirm the code above, to make sure im not chasing wrong issues.

[Spinnetti]

On mine, I had to add a small straight spacer, but that's it. Have never got a cel, but still have to flash back to stock to pass (uni tune, APR downpipe so not apples to apples)

[Elvir]

7/28/2022
Test 1: made it to 26miles before CEL
Test 2: made it to 33 miles before CEL

this is so frustrating.

does anybody have any experience with this spacer?

P2270 is the code for the O2 sensor signal stuck lean

Meaning the 02 sensor spacer is causing the 02 sensor to not get full reading.

The S3 is a ULEV. Ultra Low Emission Vehicle. You cant trick fuck it into passing emissions.

Only way to pass is with the stock cat in place.

I passed emissions last year, so i know it can be done. I was thinking about that code last night and had some thoughts.

As mentioned above P2270 means its not getting full reading or spacer is pushed too far out, so Adding more gap as mentioned in post above would not be the answer.

My car runs an aggressive tune with Crackles and pops which means it dumps a little more fuel. When I took the sensor out, it looked to be quite a bit dirty with noticeable carbon buildup.

I cleaned it up and am hoping it works.

If it does not work, I would expect a different reading, maybe even P2271 (stuck rich). If I do not get a different reading, I will place the sensor directly onto the downpipe. If nothing happens still, then I have to assume that its a bad sensor.

Test 1:
*Cleaned sensor, and started over.
*Drove 10 miles, Car cooled off for several hours
*Drove to 43.5 miles, (EVAP System Mon – OK). * Longest Distance so far w/o CEL.
*Drove to 45 CEL (P2270)

Test 1:
*Placed the cleaned O2 sensor Directly into the Hi-Flow Downpipe
*Drove 80 miles w/o CEL.
-EVAP System Mon – OK
-EGR System Mon – OK


Note: No CEL, but pulled codes to see if anything is showing up and sure enough P2270 is still showing, Im assuming as a soft code.


8/1/2022
Test2:
Drove to 82 miles, CEL. (P2270)

[Elvir]

My expectation with a hi-flow cat would be that a sensor would throw a different code when it is directly in downpipe versus spaced out.(if it does it)
I am getting same code regardless of where I put the sensor.

Last year, when I put the spacer on, I was able to get through readiness and pass on first try.

Is it possible all this testing is with a bad sensor, regardless of downpipe?

[MikTip]

In had to replace my 02 sensor after it was behind the high flow cat. Not sure what it does to the 02 sensor, but a new one fixed my issue.

[Elvir]

Thank you. Which brand did you get? I see that ECStuning has “oe” for $75

Test1:
* Took the O2 sensor out. Night before, I dipped it into fuel for 4 hours and to get cleaned and installed it back in with a straight spacer.
*Warmed up the car
*Drove to 7.4 miles.
*(EGR System Mon - OK)
*Pulled a Soft code: P2271 - Bank 1, Sensor 2, Signal Stuck Rich. (Finally something different)
*I did drive the car a bit more aggressively, not redlining it, but not noodling and certainly above 55-60mph on highway.
*I did order a new sensor for testing in case this one ended up with same P2270 code, but I think I will try a few more tests now that I got a different code.

Test 1: Continued.

*Lunch Time Drive: Let car warm up for 4 minutes. (until oil temps started to get a reading)
*Drove to highway, and put it on cruise control for 10 minutes at 56mph.
*checked Readiness and ALL CODES WERE CLEAR at 10 miles of driving.
*Next 25 miles I was scrambling to make it to Emissions, and Passed!

*Cold Start: Made it to 45 miles an CEL. (P2270)

[Elvir]

PASSED

Ok, now I would like to have a dialog and am open to inputs. From the time I put the car into stock mode it was CEL after CEL. I managed to drive from 13 - 80 miles in between those CEL and my distance kept getting longer but not all codes were reset. I have tried Different spacers and no spacers and still received the same P2270 (lean) code.

After dipping the sensor into gas for 4 hours, that must have cleaned it up to get a soft code of P2271 (rich) but no CEL, at which point my car set all I/M readiness codes in only 10 miles.

Now, I am curious if it was dumb luck or if reading lean was just going to postpone the inevitable. I want to know if something about that code kept the readiness from not setting as the P2271 code did.

Any thoughts For future?

[texasboy21]

I thought most people left $100 on the dash during the inspection process. That usually helps getting the monitors to pass.
