System not ready-Emissions

[jerseyboosted91]

Hey guys so I’ve been up for inspection in jersey for some time now and have stopped being lazy and finally have taken my car to get the car inspected. Everything checked out except the part where the guy was asking me if I had work done on my car recently or if my battery died because on the computer it comes up as system not ready so he failed me for inspection right then and there.

Fast forward to a week later and I had asked my shop where I take my car and they told me to just drive it for a few miles and my car will be fine. I put on about 220 miles on my car and it still says system not ready. I’m stage one with an x pipe and an intake but I really don’t think those would be causing the issues. I even flashed the car back to stock for the heck of it and it still says system not ready.

Can anyone shed some light on this matter? Thanks

Is it throwing any codes? Can you post the output of auto-scanning with VCDS?

Have you cleared the code and it came back? If so, how long between intervals?

[Chris@EPL]

Any time you flash a car or clear codes it rests all of the readiness monitors and it takes time, miles and hot and cold starts to reset all of them. That is assuming that the tune does not have them turned off as that will be an auto fail every time.

Yeah I’ve cleared the codes and it’s come back. I could try posting a pic today but need to go back to my office first since I left my carista in my desk lol

That’s what I was thinking at first however I flashed it back to stock and I’m still having the same issue.

Probably referring to the readiness not being set.

http://www.ross-tech.com/vcds/tour/readiness.php

There is 8 of them and they need to be all set (most states) in order to pass inspections. Flashing the car, changing battery, or any issues with that related code can cause it not all be set. Usually takes a couple drive cycles to have them all set on a properly running car (tuned or not). I would make sure your CEL is not on and check for any pending codes in the car. Clear codes (especially after flashing a tune) and run the car and then check readiness again.

That is 100% my issue but I’ve tried resetting it already and drove about 4-500 miles the first and said it still wasn’t ready so I reset it right then and there. On the second time currently and I’ve done about 300 miles currently but will check it today.

Odd. When you get your Carista I would see if there are any codes. Some soft codes shouldn't prevent readiness from being set. I have a soft code for my coolant pump, but that's because I have the AWE kit with their coolant pump and never had issues on inspections/readiness. Check engine light on?

Nope check engine light was not on. When I scanned for codes only 3 of them came up. Two for my gas door solenoid where now I have to physically turn off my car open my door and use my key fob to unlock my gas door whenever I’m at the gas station which is a problem for a different day lol and then the third code was for tire pressure

Which readiness modules are showing as not ready? Who tuned your car?

Stop re-flashing and clearing codes. Every time you do that the readiness monitors reset and you have to go through drive cycles again. Soft codes that don't trigger a CEL shouldn't effect the readiness monitors and inspection. I believe the EVAP system is what takes the longest to go ready. If you drive 400 highway miles on say 3 or 4 start ups the monitors might not all be ready so just be patient.

that's why its fucked up. Guarantee whoever DIY tuned it either has the some of the readiness modules coded out or just not set up properly. Again, which modules are not showing as ready?

[Tuning@VelocityAP]

You can drive hundreds of miles for weeks and still not complete the OBD drive cycles required to complete the OBD Readiness Codes.

The OBD Readiness codes are NOT fault codes indicating an issue is present, their mainly for emissions stations and to verify a repair has completed.

So, for example lets say your Secondary Air Pump eats the dust and a code is stored. A tech diagnoses and flags the pump as the fault and replaces. The only way this tech is going to know the Secondary Pump issue is resolved, is by clearing the faults and completing the drive cycle monitors to show readiness is complete and OK. Otherwise the tech would just be replacing a part and hoping for the best...if the readiness monitor failed for the secondary pump and it's been replaced, this would prove the pump was not the fault or main reason for the fault and issue is still present.

The reason emissions stations look at the readiness status, is to know if the vehicle is running as designed. Meaning if the emissions components are working on your vehicle, then all the readiness monitors will show completed/passed status (OBD C.A.R.B Approved). If you have a flat battery or reset your engine fault codes (even with no codes stored), this will clear out all readiness monitors and sometimes wipe out fuel adaptions and misfire profile corrections. In order to learn all this drive cycle gunk again, you have to follow a step-by-step list of what the ecu needs to see in-order to run the next drive cycle.

Snap-on has a good guide to follow, https://www.snapon.com/Files/Diagnos...CodeCharts.pdf

Look at pages 2 and 3, temps of engine, speeds, times of run and off soak need to be followed. Some emissions stations will allow 1-2 readiness not complete and others will require all be OK status to pass inspection.

Try the link posted to complete the monitors status, then use a scan tool to check your readiness monitor and/or drive cycle status, just make sure to not clear any codes, btw if you get an engine fault code/DTC , you will not be able to complete the readiness until fault code is addressed/repaired/resolved.

If your still not completing a particular drive cycle even after the guide in link was followed, it's possible your tune is stopping a monitor from completing. If you can flash back stock on your own and have no issues with any parts added, that would be the best bet to attempt completing the monitors(with stock file loaded back). If you cannot flash back stock on your own, contact your tuner and inquire about the exact readiness monitors not completing and inquire with them for further guidance.

x2 it can take weeks sometimes for readiness to be set. Stop resetting and keep driving they will be set eventually. That is if the tuner didn't mess with any of them and turned them off.

[jerseyboosted91]

Duly noted guys thanks for info. Going to check to see if works today with my carista. If not I’ll just take it out NOT RESET IT and continue to drive lol

Aren't there VCDS tests to check and set each of the readiness monitors?

[fx_warrior]

A few years I did the Audi thing where you drive and do certain maneuvers over like 20 miles of drive and it worked fro me, everything was ready I'll see if I can find it. Although that was for a b6 a4, but I've read it works for all of them.



EDIT.... Boom found it https://www.snapon.com/Files/Diagnos...CodeCharts.pdf Go to page 3.


Yes I did this twice in fact and worked both times. A little tip I found out the hard way, after you're done with the last step you have to pull over put the car in park and the final monitor should ready. I forget which one it was that took the longest.


The old b6 a4's had this torque converter CEL that wouldn't go away. So for two inspections I had to do this, since the only way to get rid of the CEL was to disconnect the battery and get the inspection done before I turned the car off and back on LOLLLLL.

It worked though and again I read this is SUPPOSED to work for all years and makes.

Yeah there is ways to force readiness and run the readiness tests while stationary, but I don't think this guy has VCDS.

[TC_S4]

Each time I go to the dealer, I flash back my tune to stock and back to stage 2 after, therefore emission not ready. I did it like 4-5 times and every time it’s ready. Just make sure you don’t have codes or soft codes otherwise it will never be ready, no matter how long you drive. You don’t need to drive the car a lot, just follow the steps, it’s 12 to 15 minutes process . Do it when there are no traffic because you need to maintain 55mph for 3 min on step 3 and 5 min on step 6.

I don’t need emission test, just doing it for the fun of it.

Thanks for all the help guys. I’m out of town for work until next Monday night so I’m going to have to play with it then. Hopefully it solves my issue.
