APR Stage 2 on 4.0 TT 2013 (Failed Emissions)

[2012S4]

I have the APR Stage 2 on 4.0 TT on my 2013 S8. 29,000 miles

Failed emissions test seven months ago. My original APR dealer closed so I had to choose another APR dealer.

Back and forth to an APR dealer four times. Six calls to APR. Failed emissions test five times during this six month period. Six calls to APR.

Finally after $1200 of work finally passed emissions.

I am really pissed at APR. They gave bad information on how to resolve this multiple times. To the most outrageous idea of putting my old downpipes backon, flashing back to stock and then going to the emissions test. This would cost almost $2000 in labor just to pass emissions.

Has anyone else lived thought an issue like this? Has anyone just passed emissions with Stage 2 on a 4.0 TT?

After spending $6,000+ to get to Stage 2. Spending $1200 to pass the test was a waste.

Just felt they did not take it seriously.

People going with APR downpipes who are concerned about emissions are not doing their due diligence in terms of research. O2 spacers MAY help, but not a guarantee. AMS downpipes supposedly have not had an issue due to the cats being in the stock location.

[arrivalanche]

This is a joke, right?? You seriously thought you could go crazy with engine mods and have no issue passing smog? Bwhahahahha. Id SERIOUSLY be surprised if I passed even with O2 sensor extensions. Be realistic and dont blame everyone else. Its pay to play.

My understanding as to why some folks fail after flashing APR back to stock is that they haven't driven enough cycles of different types of driving to be able to set the O2 sensors back to the 'ready state'- not sure of your location, but most places in the US simply use OBD2 testing rather than a 'sniffer' at the tailpipes, and as long as the O2 sensors are read as ready and functional, you should be good to go. If you are in a location that actually tests the exhaust, you are likely out of luck with APR downpipes, and potentially with AMS as well, as the high flow race cats just aren't doing the same job as the stock cats. If this is the case, then yeah, putting the stock downpipes back on temporarily will do the trick, but clearly painful.

If you truly have a Chiron in your garage, another option would be to keep a stock S8 on hand just for emissions testing!

[Dasquade]

I will know in a month (Belgium).
What i did was mounting back the stock exhaust (for sound in the first place), but removed the stock first mufflers. Cutted them open and placed 200cell cats in them and welded the stock muffler shields back on (barely fits but it fitted). Already did one garage emission test as test. As long you keep a steady 2000rpm, it keeps CO just under the tresshold. Running 10% bio ethanol aswell that helps lower emmissions aswell. Since the second sensors are written out if goes up and down a little in my case but on 2000rpm all seam to be good (crossing finguers). Swapping exhausts is definatly less work then swapping downpipes!

[Chris Morales]

Are you complaining about an emissions (sniff) test or just a plug-in OBDII inspection?

If just a plug-in test, there is a procedure for passing that has been posted here many times. Basically, switch to the stock program, start the car, drive it 30 miles, check for "ready" status with a handheld OBD II reader, and drive straight to the inspection station without turning the motor off.

If an actual sniff test, it's unrealistic to expect no difficulties passing after switching from massive stock cats to the tiny ones in the APR units.

[ryanlada]

I have stage 2 on my 2016 S6 and to prove to myself that the ODB will show ready, I have switched to stock mode this morning. I have secondary o2 spacers so i should be able to run indefinitely this way without codes and ready on all the emissions tests. I have about 60 miles of driving to do today and i will report back.

[jsmonet]

OP must be trolling. It's too silly to think that reducing the efficacy of your catalysts would have no effect on your emissions and ability to pass a sniff test.

If it's a readiness test, that's been covered to death.

The simple fact is that you should always be prepared to go back to stock exhaust components for smog tests. I've done that with every car, and where it was prohibitively annoying, I didn't install downpipes.

46 miles and three restarts since selecting APR Stage 2 "Stock" mode on my program switching. No codes. I will run for next couple days for a few hundred miles. I have the APR downpipes connected to stock sports exhaust. Vibrant J 02 spacers with smallest restrictor installed.

Can someone confirm the "coded out" secondary 02 sensors show ready here? I'm not sure how this compares to a stock readiness report. Maybe someone with a Stock ECU can post their readiness readings?

[carx7]

wow. Tough crowd. He said APR gave bad advice. I won't speculate what was or wasn't said to him but I had a similar experience in getting advice for resolution that didn't work. Mine came from my APR dealer and it included a pitch to install the APR DPs on my car. While it may be obvious to some that an APR DP with cats won't pass emissions out of the box that certainly isn't obvious to the world. I was given other advice from APR through the dealer that included spacers, drive cycles, etc, etc.

As to the post " go crazy with engine mods"... seriously? A tune and an exhaust hardly qualifies as crazy. Really, that barely scratches the surface.

Pay to play? Maybe. But there are other platform tunes that can readily pass emissions without uninstalling the tune and while utilizing catless exhausts.

I love the car and what a tune does, but I've struggled more with emissions on this car than I have others I have modified in similar ways. It doesn't need to be that way.

Every turbo car I’ve experienced has been the same when regarding messing with the stock downpipes. Putting the stock parts back on is sound advice.

Another 20 miles today, no CEL.

Does running in stock mode on the APR Stage 2 Tune and downpipes lead to a CEL without spacers for anyone?

Not sure I understood this question. I have an APR stage II car and have tried numerous combinations with zero success.
I have tried with and without spacers from 034 and from Fabspeed. I have tried with and without APR catted downpipes and all combinations of that. no luck.
I tried stage II stock map and stage II removed entirely. No luck.

I keep reading that people are successful with the vibrant J spacers as you are finding success. My next path was to purchase my 3rd set of spacers (Vibrant J) and give those a whirl when my car was totaled. The new car is getting Russian catted DPs to ride on the theory(and guarantee from my the DP supplier) that pipes with a factory location cat will work without spacers for no CEL.

Agree with this...downpipes and a tune is not "going crazy" on engine mods, that's a joke

[bhamcarnut]

Anytime you change an emissions part with a non OEM part there is a risk of not passing the test. A tune changes so many aspects of how the motor runs with fuel delivery and timing among other things. Most performance cars have to be de-tuned so they actually pass emissions testing in the US. Add the two together and your probability gets much lower of passing. I am originally from California and have had many cars that had to be adjusted to pass smog. It’s a PIA but when I passed and put the parts back on, I immediately remembered why it’s worth it. You can also just move to Alabama where we don’t have to deal with emissions testing.

I was wondering if the apr tune would throw a cel for the secondary 02 sensors in "stock" mode if you were to drive it indefinitely. I drove 100 miles over 3 days with about 6 driving cycles and no cel. Wanted to make sure the apr stock tune wasn't hiding the problem from me. I'm not sure how else to check, I ran an EPL tune for thousands of miles on the apr pipes and no issues using the secondary 02 spacers (they don't code out the secondary sensors). Really just wondering what the difference is. Maybe something with the model year difference? 2014 vs 2016? It's always struck me as odd the different results, makes me worry that I'm on some ragged edge and i may battle this when it comes time next year for me to pass the scanner based test.

[ryanlada]

How many miles on your apr down pipes? Maybe the catalysts are bad? Mine have about 20k on them now.

I would expect that your car won't throw a CEL at all, given that you were fine running the EPL tune. What I'm uncertain of is to whether your secondary O2 sensors are able to achieve a 'ready' state, or whether they are still 'coded out' even in APR stock mode. I'd previously read from others that in order to be able to get both the primary and secondary sensors in a 'ready' state, that you need to go back to your APR dealer to have the APR tune completely removed. Hopefully this is incorrect, and you can achieve ready state by simply choosing the 'stock file' map on your own at home, which would be incredibly more convenient. Would you mind sharing how you come up with that readiness test in VCDS? I've not seen that one before.

The sequence of Failures: Car has selectable stage 2 (4.0 TT): Stock/91/93/100/Valet mode

5000 miles on APR downpipes about 1.5 years old.

1- Car tuned in 93 Mode: FAILED

2- Car tuned in Stock Mode: FAILED (Engine light on, started throwing errors)

3- Car tuned in Stock Mode & Spacers added: FAILED (Engine light on, started throwing errors)

3a- APR said maybe put old downpipes back on. Cost almost $2000k to remove and replace. < I did not take this option

4- Car flashed back to stock tune removed: FAILED (Engine light on, started throwing errors) (LOGS Below)

5- Car flashed back to stock & different set of spacers added: Passed

6- Car tuned back to Stage 2 (No Engine Light)


Total - Six months of trial and error. Many days and dollars wasted.

Thank you for the people who shared the same issues. No thanks to "pay to play" and MOD trolls.

My experience was VERY similar to above.
My APR pipes has less than 5k miles on them.
I too was told that the car would not pass "ready state" with the tune installed even when in stock mode and that I had to remove the tune entirely.
I tried this with various spacers on the APR DPs and was not successful. The 034 spacers looked nice but acted the same as stock. The fabspeed catted spacers threw the "slow response" code.

Counter to my personal experience: A local contact installed APR DPs on his S6 and used Vibrant J spacers. He is running GIAC tune (IIRC) and had no issues with CEL or readiness. Apples and Oranges with the tune difference I suppose, but it is an interesting data point compared to my experience.

[iamredeer]

Listen, I went through this same issue last month. I went ahead and bought the APR Mobile. I literally cleared all my codes and went into stock mode (Drove Like Shi*). Drove roughly 20 miles to the Testing facility and I passed with flying colors. Didn't have to pull any mods off to pass.

Mods:
Downpipe
Stage 2 tune
TCU Tune
Resonator delete

[iamredeer]

FYI to pass ready state you need to switch the car to stock mode. Do NOT go over 3.5K rpms until you get to the facility. The Stage 2 tune does not allow you to be in the ready state when being checked for codes. Also pull your dongle out of the Plug when arriving to the testing so the tester can plug up.

[ryanlada]

I can't figure out how to tell if the secondary sensors are enabled or not. I have not yet found a difference between apr stock and 93 modes. May need to compare to someone else's car.
Anyone know where to look in vcds to see the secondary sensor status?

Why stay under 3.5K? Curious.

Not sure I follow.
Moving back to the stock map codes does not magically show readiness on the sensors. A drive cycle must be completed and the instant this is completed, the CEL comes on (at least in my car). There is no in-between period whereby all sensors show "ready state" and there is no CEL. If you cleared all your codes and then drove straight to an inspection station it seems unlikely that your sensors are in a "Ready state"

Plenty of people have commented that their state allows 1 sensor to be "not Ready" but in Texas, we must show all sensors Ready.

If you haven't yet, try the Vibrant J-shaped spacers using the restrictors with the smallest hole. A bunch of folks including myself have had good luck in not throwing a CEL while using the APR downpipes (it obviously doesn't matter when you're running the APR tune, but this ought to let you drive around on a stock file long enough to get your sensors ready and not throw a CEL).

[carx7]

That was going to be my next step, but I've moved onto an Akra system and have some of Mike's downpipes in my garage. He's guaranteed me no CEL issues, no spacers, no hassle... so I'm going to try that. Hope to get car back and install pipes this weekend.

To the OP's comments, I'd like to see APR advertise in bold letters that their setup WILL NOT pass emissions as they are.... In my mind,what's the point of selling a catted system if it won't pass emissions? Either go catless, or include the spacers required to make it work.

I'm in Texas and we can have one test show as "not ready" and still pass. I am confident you can get the car to pass if you do what I have done. I've passed inspection twice with the APR downpipes. You don't need to change hardware. Clear all codes and switch to the stock map right before starting the car cold, start the car and drive it for about 30 miles, and pull into the inspection station without turning the car off. Scan while the car is running to see if your tests are ready. There is an "in-between" period and you're just not finding it.

"For vehicles year model 2001 and newer, we allow one (1) non-continuous monitor to be Not Ready and still pass the test, but two (2) or more Not Ready's will cause the vehicle to fail."

[arrivalanche]

Another 20 miles today, no CEL.

Does running in stock mode on the APR Stage 2 Tune and downpipes lead to a CEL without spacers for anyone?

Yes. I didnt realize when I took mine home after getting stage 2 and downpipes that I was still in stage 1 mode and I got a CEL twice. Once I activated stage 2 it never came back.

[arrivalanche]

Id like to tack on to this conversation and ask if using spacers on non-catted downpipes will allow you to take your car in with the DPs still installed and no tune installed and no get you flagged on a scan? I know this is opening the tune/TD1 can of worms so lets set that aside. Ive had mine scanned 10+ times after taking off my Stage 1 APR tune and never got flagged so lets not go into that.

[hmuller]

Another 20 miles today, no CEL.

Does running in stock mode on the APR Stage 2 Tune and downpipes lead to a CEL without spacers for anyone?

Yes. I switched to stock mode last night to see how long it would take to get the CEL. After my 10 mile commute home no CEL but two readiness bits were still not set (EVAP and O2 sensors). Drove another 2 miles this morning and parked the car to bring my kid to school. On my way from school to work the CEL came on. So a total of about 18 miles with an overnight stop and a short stop did it. I still have three years to go before my first inspection so that should be time enough to work out the right driving distance and timing to get readiness for OBD testing or to install the spacers.

[TROTTERS4]

You can't expect to pass emissions with catless downpipes. Now they have updated the emissions testing where 3 sensors need to read ready, not just the O2 sensors... Good luck.
